The “gateway” drugs are merely those that are available at an earlier age than the harder drugs. Researchers have noted in an extensive review that it is dangerous to present the sequence of events described in gateway “theory” in causative terms as this hinders both research and intervention. There are concerns surrounding memory and cognition problems, risk of addiction, and the risk of schizophrenia in young people. A number of trials in humans were conducted by Guy and colleagues to explore administration route efficiency of sprays, an aerosol, and a nebuliser containing CBD or CBD and THC (Guy and Flint, 2004; Guy and Robson, 2004a,b).

Bloor RN, Wang TS, Spanel P, Smith D. Ammonia release from heated ‘street’ cannabis leaf and its potential toxic effects on cannabis users. Epilepsy centers provide a team approach to caring for people with seizures Delta-8 and epilepsy. Comprehensive testing is available to diagnose whether a person has seizures and the type of epilepsy they may have. It causes seizures that stem from the medial or lateral temporal lobes of the brain.

Between 15 to 30 percent of children with intellectual disabilities have epilepsy. Between 30 and 70 percent of people who have epilepsy also have depression, anxiety, or both. One treatment that may be available in the future is deep brain stimulation. It’s a procedure in which electrodes are implanted into your brain. The generator sends electrical impulses to the brain to help decrease seizures.

Cannabis was introduced to the New World by the Spaniards in 1530–45. Following an 1836–1840 travel in North Africa and the Middle East, French physician Jacques-Joseph Moreau wrote on the psychological effects of cannabis use; he was a member of Paris’ Club des Hashischins. CBD PODS In 1842, Irish physician William Brooke O’Shaughnessy, who had studied the drug while working as a medical officer in Bengal with the East India Company, brought a quantity of cannabis with him on his return to Britain, provoking renewed interest in the West.

In January 2019, the UK Food Standards Agency indicated it would regard CBD products, including CBD oil, as a novel food having no history of use before May 1997, and stated that such products must have authorisation and proven safety before being marketed. The deadline for companies with existing products to submit a full and validated novel foods application with the FSA is 31 March 2021; failure to do so before this date will exclude those companies from selling CBD. New products containing CBD after this deadline will require a fully approved application. Prescription medicine for therapeutic use containing two percent (2.0%) or less of other cannabinoids commonly found in cannabis (such as ∆9-THC). Currently, Uruguay and Canada are the only countries that have fully legalized the cultivation, consumption and bartering of recreational cannabis nationwide.

At higher concentrations, CBD acts as an inverse agonist of 5-HT1A receptors. It is an allosteric modulator of the μ- and δ-opioid receptors as well. The pharmacological effects of CBD may involve PPARγ agonism, inhibition of voltage-gated cation channels, and intracellular calcium release. Some studies state that while there is no proof for the gateway hypothesis, young cannabis users should still be considered as a risk group for intervention programs. Other findings indicate that hard drug users are likely to be poly-drug users, and that interventions must address the use of multiple drugs instead of a single hard drug.

In the USA and other territories there are, however, numerous veterinary nutraceutical products available OTC. The lack of clarity in the regulations governing veterinary hemp food supplements allows for products of questionable quality to flood the Ava market, which may pose a risk to the wellbeing of pets and owners. Many claims are made for the therapeutic benefit of cannabidiol that are not backed by sound evidence. Cannabis research is challenging since the plant is illegal in most countries.

This study showed that the addition of CBD to a traditional seizure medication decreased the frequency of drop seizures significantly in children and adults with LGS. The most common side effects were sleepiness, decreased appetite, diarrhea, change in liver function, fatigue, malaise, asthenia , rash, insomnia, sleep disorder, poor quality sleep, and infections. In controlled trials, the rate of stopping the medicine due to any side effect was small and happened most in people taking the higher dose of Epidiolex. In controlled and uncontrolled trials in people with Lennox-Gastaut syndrome and Dravet syndrome, 689 people were treated with Epidiolex , including 533 people treated for more than 6 months and 391 people treated for more than 1 year.

In December 2012, the U.S. state of Washington became the first state to officially legalize cannabis in a state law , with the state of Colorado following close behind . On 1 January 2013, the first marijuana “club” for private marijuana smoking was allowed for the first time in Colorado. The California Supreme Court decided in May 2013 that local governments can ban medical marijuana dispensaries despite a state law in California that permits the use of cannabis for medical purposes. At least 180 cities across California have enacted bans in recent years. In Uruguay, President Jose Mujica signed legislation to legalize recreational cannabis in December 2013, making Uruguay the first country in the modern era to legalize cannabis. In August 2014, Uruguay legalized growing up to six plants at home, as well as the formation of growing clubs, and a state-controlled marijuana dispensary regime.

But there isn’t enough research to show that the whole plant works to treat or cure these conditions. The U.S. Food and Drug Administration has not approved the marijuana plant as a medicine. For others who are looking to lose weight, this effect could be considered a disadvantage, although epidemiological studies suggest cannabis users don’t have increased risk for diabetes or obesity compared with nonusers. No matter how you use cannabis, it can cause immediate and long-term effects, such as changes in perception and increased heart rate.

The surgeon makes cuts in the brain to interrupt the nerve pathway. In order to diagnose epilepsy, other conditions that cause seizures should be ruled out. Your doctor will probably order a complete blood count and chemistry of the blood. Your medical history and symptoms will help your doctor decide which tests will be helpful.

It may be useful in adjusting your medications or exploring other treatments. Myoclonic seizures cause spontaneous quick twitching of the arms and legs. Clonic seizures are characterized by repeated, jerky muscle movements of the face, neck, and arms.

Onset of effects is felt within minutes when smoked, but may take up to 90 minutes when eaten. The effects last for two to six hours, depending on the amount used. At high doses, mental effects can include anxiety, delusions , hallucinations, panic, paranoia, and psychosis.

Forty-four percent of American 12th graders have tried the drug at least once, and the typical age of first-use is 16, similar to the typical age of first-use for alcohol but lower than the first-use age for other illicit drugs. In the US, men are over twice as likely to use marijuana as women, and 18–29-year-olds are six times more likely to use as over-65-year-olds. In 2015, a record 44% of the US population has tried marijuana in their lifetime, an increase from 38% in 2013 and 33% in 1985. On 17 October 2015, Australian health minister Sussan Ley presented a new law that will allow the cultivation of cannabis for scientific research and medical trials on patients. In December 2013, Uruguay became the first country to legalize growing, sale and use of cannabis.

Cannabis tea is made by first adding a saturated fat to hot water (e.g. cream or any milk except skim) with a small amount of cannabis. Vaporizer, which heats any form of cannabis to 165–190 °C (329–374 °F), causing the active ingredients to evaporate into vapor without burning the plant material (the boiling point of THC is 157 °C (315 °F) at atmospheric pressure). The mission of the Epilepsy Foundation is to lead the fight to overcome the challenges of living with epilepsy and to accelerate therapies to stop seizures, find cures, and save lives. Learn about the Epilepsy Foundation’s state and federal advocacy efforts on removing barriers to cannabis research and supporting access to medical cannabis in consultation with the treating physician. While the carry-on quantity of liquids is less than 3.4 ounces/100mL, TSA allows larger amounts of medically necessary liquids in reasonable quantities for your trip. However, you must declare them to security officers at the checkpoint for inspection.

How Genetics Affect Cannabis Treatment For Epilepsy

What happens during a seizure is one of the most important pieces of information. And, since seizures rarely happen in a doctor’s office, the information given to the doctor and other health care professionals by you or other witnesses is extremely important. That includes about 3 million people in the United States, where there are 150,000 new cases of epilepsy diagnosed each year. Dozens of other avenues of research into the causes, treatment, and potential cures for epilepsy are ongoing.

Plant Breeding

The most common side effects of CBD included sleepiness, diarrhea, fatigue, and decreased appetite. Within the 25 included studies, Cmax was reported on 58 occasions , Tmax on 56 occasions and area under the curve (AUC0−t) on 45 occasions. These data from plasma/blood are presented in Figures 2A–C. The AUC0−t and Cmax of CBD is dose-dependent, and Tmax occurs between 0 and 5 h, but does not appear to be dose-dependent. The causes of psychosis are complex and researchers are still trying to understand them fully.

A study in 14 male and female cannabis smokers reported 15.4% detection in frequent smokers with no CBD detected in occasional smokers in whole blood analysis (Desrosiers et al., 2014). In plasma however, there was a 53.8 and 9.1% detection in the frequent and occasional groups, with corresponding Cmax of 1.1 ng/mL in the frequent group, and below limits of detection in the occasional group. THC was demonstrated effective in a small crossover clinical trial versus placebo in 11 agitated dementia patients with Alzheimer’s disease (Volicer et al., 1997). THC was also observed to be an acetylcholinesterase inhibitor in its own right, as well as preventing amyloid β-peptide aggregation in that disorder (Eubanks et al., 2006).

People mistakenly believe that marijuana is completely safe because it is a plant or oil from a plant. Marijuana or cannabis in general has a number of side effects depending on how it is used. For example, if smoked, the negative effect of smoking on a person’s lungs and heart also apply to marijuana. A number of clinical trials are active and recruiting people, including studies using Epidiolex in people with Tuberous Sclerosis Complex and Sturge-Weber Syndrome. The study measured the change in the number of convulsive seizures over the CBD treatment period, as compared to baseline period.

Cannabis Drug

Only 1 study reported the bioavailability of CBD in humans (31% following smoking). Overall, considerable variation was observed between studies, although they were very heterogeneous, and further work is warranted. Various cannabis component combinations or cannabis extracts should be examined via high throughput pharmacological screening where not previously accomplished. Another goal is the investigation of the biochemical targets of the cannabis terpenoids, along with their mechanisms of action, particularly in the central nervous system. Possible techniques for such research include radio-labelling of select agents in animals with subsequent necropsy.

CBD also displays therapeutic promise in other disorders such as schizophrenia and post-traumatic stress disorder. If we are to understand the actions of CBD in those disorders and increase the success rate for treatment, these groups of patients and their distinct characteristics must be assessed as they may not be comparable to a healthy volunteer population. From previous investigations including animal studies, the oral bioavailability of CBD has been shown to be very low (13–19%) (Mechoulam et al., 2002). It undergoes extensive first pass metabolism and its metabolites are mostly excreted via the kidneys . Plasma and brain concentrations are dose-dependent in animals, and bioavailability is increased with various lipid formulations (Zgair et al., 2016).

After single doses of 5 and 20 mg CBD, mean Kel (1/h) was reported as 0.173 and 0.123 (Stott et al., 2013a). Following 20 mg CBD administration through a nebuliser and pressurized aerosol, mean Kel was reported as 0.98 and 0.43, respectively, while 20 mg CBD administered as sublingual drops was reported as 0.37 . Ligresti A, Moriello AS, Starowicz K, Matias I, Pisanti S, De Petrocellis L, et al. Antitumor activity of plant cannabinoids with emphasis on the effect of cannabidiol on human breast carcinoma. Various sources highlight the limited therapeutic index of pure THC, when given intravenously (D’Souza et al., 2004) or orally (Favrat et al., 2005), especially in people previously naïve to its effects. CBD modulates the psychoactivity of THC and reduces its adverse event profile , highlighted by recent results above described.

Their yield is less than 1% in most cannabis assays, but they may represent 10% of trichome content . Evolutionarily, terpenoids seem to occur in complex and variable mixtures with marked structural diversity to serve various ecological roles. Terpenoid composition is under genetic control , and some enzymes produce multiple products, again supporting Mechoulam’s ‘Law of Stinginess’. CBG , the parent phytocannabinoid compound, has a relatively weak partial agonistic effect at CB1 and CB2 (Gauson et al., 2007). Older work supports gamma aminobutyric acid uptake inhibition greater than THC or CBD (Banerjee et al., 1975) that could suggest muscle relaxant properties. Analgesic and anti-erythemic effects and the ability to block lipooxygenase were said to surpass those of THC .

United Kingdom

Minimal evidence of plasma accumulation has been reported by chronic dosing studies over 5–9 days (Sellers et al., 2013; Stott et al., 2013a). A dose of 20 mg/day resulted in a mean Cmax of 1.5 ng/mL and mean AUC0−t of 6.1 h × ng/mL while 60 mg/day equated to a mean Cmax of 4.8 ng/mL and AUC0−t was 38.9 h × ng/mL (Sellers et al., 2013). In another study, Cmax increased dose-dependently from 0.4 to 1.2 and 2.2 ng/mL following 5, 10, and 20 mg single doses, respectively, and from 0.5 to 1.1 and 3.2 ng/mL, respectively following chronic dosing over 9 consecutive days (Stott et al., 2013a).

Using cannabis during pregnancy can also affect the developing baby. The child may have trouble with memory, concentration, and problem-solving skills. THC can also lower pressure in the eyes, which can ease symptoms of glaucoma for a few hours.

As of September 2019, 1,085 people contacted US poison control centers about CBD-induced illnesses, doubling the number of cases over the 2018 rate and increasing by 9 times the case numbers of 2017. Of cases reported in 2019, more than 33% received medical attention and 46 people were admitted to a hospital intensive care unit, possibly due to exposure to other products, or drug interactions with CBD. Studies conducted by the FDA from 2014 through 2019 have determined that a majority of CBD products are not accurately labeled with the amount of CBD they contain. For example, a 2017 analysis of cannabidiol content in oil, tincture, or liquid vape products purchased online in the United States showed that 69% were mislabeled, with 43% having higher and 26% having lower content than stated on product labels. Research indicates that cannabidiol may reduce adverse effects of THC, particularly those causing intoxication and sedation, but only at high doses.

A recrudescence of interest accrues to this compound, which is a CB1 antagonist at lower doses (Thomas et al., 2005), but is a CB1 agonist at higher doses . THCV produces weight loss, decreased body fat and serum leptin concentrations with increased energy expenditure in obese mice (Cawthorne et al., 2007; Riedel et al., 2009). THCV also demonstrates prominent anticonvulsant properties in rodent cerebellum CBD Gummis – Was ist meine perfekte Dosis? and pyriform cortex (Hill et al., 2010). THCV appears as a fractional component of many southern African cannabis chemotypes, although plants highly predominant in this agent have been produced . THCV recently demonstrated a CB2-based ability to suppress carageenan-induced hyperalgesia and inflammation, and both phases of formalin-induced pain behaviour via CB1 and CB2 in mice (Bolognini et al., 2010).

Should A Person With Epilepsy Pursue Medical Cannabis If All Other Medications Do Not Work?

About half of adults who try the modified Atkins diet experience fewer seizures. For adolescents and adults with epilepsy, a modified Atkins diet may be recommended. This diet is also high in fat and involves a controlled carb intake. The ketogenic diet is often recommended for children with epilepsy. The diet forces the body to use fat for energy instead of glucose, a process called ketosis. If medication can’t decrease the number of seizures, another option is surgery.

Following single acute doses through oromucosal spray administration, apparent volume of distribution was reported as 26,298, 31,994, and 28,312 L (Stott et al., 2013a). Plasma apparent clearance, CL/F (L/h) has been reported to range from 2,546 to 4,741 in a fasted stated following 10 mg CBD administered via oromucosal spray (Stott et al., 2013a,c). This value decreases to 533 following the same concentration in a fed state (Stott et al., 2013b).

Medical cannabis, or medical marijuana, refers to the use of cannabis to treat disease or improve symptoms; however, there is no single agreed-upon definition (e.g., cannabinoids derived from cannabis and synthetic cannabinoids are also used). The rigorous scientific study of cannabis as a medicine has been hampered How to Use CBD Cream by production restrictions and by the fact that it is classified as an illegal drug by many governments. There is limited evidence suggesting cannabis can be used to reduce nausea and vomiting during chemotherapy, to improve appetite in people with HIV/AIDS, or to treat chronic pain and muscle spasms.

When the area of the brain responsible for seizures is too vital or large to remove, the surgeon can perform a disconnection. This involves interrupting the nerve pathway by making cuts in the brain. One type, called resection, involves removing the part of the brain where seizures originate. Teach the people closest to you about seizures and what to do in an emergency.

It is unclear, however, whether the increase in THC content has caused people to consume more THC or if users adjust based on the potency of the cannabis. It is likely that the higher THC content allows people to ingest less tar. At the same time, CBD levels in seized samples have lowered, in part because of the desire to produce higher THC levels and because more illegal growers cultivate indoors using artificial lights.

However, this should only be considered after a thorough evaluation at a specialized epilepsy center to look at whether all possible treatments (including FDA-approved new and add-on medicines, dietary therapy, devices, and surgery) have been reasonably tried. Providers do not need a special license or certificate to prescribe Epidiolex. Epidiolex is the first and only plant-based treatment derived from cannabis for use as a treatment for seizures with FDA approval.

People with LGS who had had two or more drop seizures each week during a 28-day baseline period were included. They were randomly selected to receive CBD oral solution at a dose of either 20 milligram per kilogram of body weight (20-mg cannabidiol group) or 10 milligram Is CBD Oil Legal in London? per kilogram of body weight (10-mg cannabidiol group) or matching placebo. These studies used a control group with some people taking a placebo while others were given CBD at different doses. Researchers did not know who was getting the placebo and who was getting CBD.

The United Nations’ World Drug Report stated that cannabis “was the world’s most widely produced, trafficked, and consumed drug in the world in 2010”, and estimated between 128 million and 238 million users globally in 2015. After revisions to cannabis scheduling in the UK, the government moved cannabis back from a class C to a class B drug. They believe skunk accounts for between 70 and 80% of samples seized by police . Extracts such as hashish and hash oil typically contain more THC than high potency cannabis infructescences. Australia’s National Cannabis Prevention and Information Centre states that the buds of the female cannabis plant contain the highest concentration of THC, followed by the leaves.

About 50 percent can stop taking medications after two to five years without a seizure. They can’t stop a seizure that’s already in progress, nor is it a cure for epilepsy. Your treatment plan will be based on severity of symptoms, your health, and how well you respond to therapy. In December 2020, the Federal Trade Commission initiated a law enforcement crackdown on American companies marketing CBD products as unapproved drugs. The warning also applied to hemp CBD capsules and oil that were being marketed illegally while not adhering to the federal definition of a dietary supplement.

What Studies Exist To Support The Use Of Cbd In Epilepsy?

The chemical formula of CBD was proposed from a method for isolating it from wild hemp. The oral bioavailability of CBD varies greatly across species and it is linked to the presentation and the time of administration. A 24-hour kinetic examination in dogs showed that the absorption of the cannabidiolic acid does occur, and that this molecule is absorbed least twice as well as CBD post oral ingestion. The number of research projects and scientific publications on cannabidiol and other cannabinoids in pets has surged in the late 2010s.

Smoking cannabis has also been shown to increase the risk of myocardial infarction by 4.8 times for the 60 minutes after consumption. Cannabinoid hyperemesis syndrome is a severe condition seen in some chronic cannabis users where they have repeated bouts of uncontrollable vomiting for 24–48 hours. Reviews in 2019 found that research was insufficient to determine the safety and efficacy of using cannabis to treat schizophrenia, psychosis, or other mental disorders. Addiction experts in psychiatry, chemistry, pharmacology, forensic science, epidemiology, and the police and legal services engaged in delphic analysis regarding 20 popular recreational drugs. Cannabis was ranked 11th in dependence, 17th in physical harm, and 10th in social harm. So far, the medical use of cannabis is legal only in a limited number of territories, including Canada, Belgium, Australia, the Netherlands, New Zealand, Spain, and many U.S. states.

Multiple deaths have been attributed to cannabinoid hyperemesis syndrome. Capsules, typically containing cannabis oil, and other dietary supplement products, for which some 220 were approved in Canada in 2018. In June 2018, the FDA approved Epidiolex allowing medical providers to prescribe this medication for Lennox-Gastaut and Dravet syndromes, similar to how they are able to prescribe other seizure medications. In late September 2018, the DEA rescheduled Epidiolex to Schedule V and all states and the District of Columbia have created pathways so that it can be brought to market for consumers. It is important to know that even though marijuana is a plant, it is broken down in a person’s liver like many medicines.

Certainly, the anti-anxiety and anti-psychotic effects of CBD may be of additional benefit (Zuardi et al., 1991; 2006; Zuardi and Guimaraes, 1997). A recent study supports the concept that CBD, when present in significant proportion to THC, is capable of eliminating induced cognitive and memory deficits in normal subjects smoking cannabis (Morgan et al., 2010b). Furthermore, CBD may also have primary benefits on reduction of β-amyloid in Alzheimer’s disease (Iuvone et al., 2004; Esposito et al., 2006a,b;). Psychopharmacological effects of limonene, pinene and linalool could putatively extend benefits in mood in such patients.

What Is Medical Marijuana?

This feature could counteract short-term memory deficits induced by THC intoxication . Phytocannabinoids and terpenoids are synthesized in cannabis, in secretory cells inside glandular trichomes that are most highly concentrated in unfertilized female flowers prior to senescence (Potter, 2004; Potter, 2009). Geranyl pyrophosphate is formed as a precursor via the deoxyxylulose pathway in cannabis (Fellermeier et al., 2001), and is a parent compound to both phytocannabinoids and terpenoids . After coupling with either olivetolic acid or divarinic acid, pentyl or propyl cannabinoid acids are produced, respectively, via enzymes that accept either substrate (de Meijer et al., 2003), a manifestation of Mechoulam’s postulated ‘Nature’s Law of Stinginess’.

Legalization has increased the rates at which children are exposed to cannabis, particularly from edibles. Children are at risk for encephalopathy, hypotension, respiratory depression severe enough to require ventilation, somnolence and coma. Short-term use increases the risk of both minor and major adverse effects. Edibles, where cannabis is added as an ingredient to one of a variety of foods, including butter and baked goods. In May 2019, the Transportation Security Administration updated its guidelines on traveling with CBD products.

The sentiment was repeated by Calkins , who noted the suggestion of a friend in Tunis that lemon retained the confidence of cure of overdoses by cannabis users in that region. This is supported by the observation that lemon juice, which normally contains small terpenoid titres, is traditionally enhanced in North Africa by the inclusion in drinks of the limonene-rich rind, as evidenced by the recipe for Agua Limón from modern Morocco . In his comprehensive review of cannabis in the first half of the 20th century, Walton once more supported its prescription . Caryophyllene oxide is a sesquiterpenoid oxide common to lemon balm , and to the eucalyptus, Melaleuca stypheloides, whose EO contains 43.8% (Farag et al., 2004). In the plant, it serves as an insecticidal/anti-feedant (Bettarini et al., 1993) and as broad-spectrum antifungal in plant defence . This agent also demonstrates anti-platelet aggregation properties in vitro (Lin et al., 2003).

An absence of studies has led to failure in addressing the bioavailability of CBD despite intravenous formulations being available. This is of critical importance due to the popularity of CBD products and will help interpret other PK values. Standardized and robust formulations of CBD and their PK data are required for both genders, with consideration of other factors such as adiposity, genetic factors that might influence absorption and metabolism, and the effects of disease states. Cherniakov et al. examined the pharmacokinetic differences between an oromucosal spray and an oral capsule with piperine pro-nanolipospheres in 9 men. The piperine-PNL oral formulation had a 4-fold increase in Cmax (2.1 ng/mL vs. 0.5 ng/mL), and a 2.2-fold increase in AUC0−t (6.9 vs. 3.1 h × ng/mL), while Tmax was decreased (1.0 vs. 3.0 h) compared to the oromucosal spray (Cherniakov et al., 2017a). This group further developed self-emulsifying formulations and reported again an increased bioavailability and increased Cmax within a shorter time compared to a reference spray (Atsmon et al., 2017a,b).

Higher doses of CBD (30–50 µM) induced sebocyte apoptosis, which was augmented in the presence of AEA. The effect of CBD to increase Ca++ was blocked by ruthenium red, a TRP-inhibitor. RNA-mediated silencing of TRPV1 and TRPV3 failed to attenuate CBD effects, but experiments did support the aetiological role of TRPV4, a putative regulator of systemic osmotic pressure (T. Bíró, 2010, pers. comm.). Given the observed ability of CBD to be absorbed transcutaneously, it offers great promise to attenuate the increased sebum production at the pathological root of acne.

Foods And Beverages

Caryophyllene, as a high-potency selective CB2 agonist (Gertsch et al., 2008), would likely produce similar effects, and have the advantage of being a non-toxic dietary component. All factors considered, CBD, with caryophyllene, and possibly other adjunctive terpenoids in the extract, offers significant promise in future addiction treatment. Over 100 phytocannabinoids have been identified (Brenneisen, 2007; Mehmedic et al., 2010), but many are artefacts of analysis or are produced in trace quantities that have not permitted thorough investigation.

Lebanon has recently become the first Arab country to legalize the plantation of cannabis for medical use. Marijuana or marihuana consists of the dried flowers and fruits and subtending leaves and stems of the female Cannabis plant. This is the most widely consumed form, containing 3% to 20% THC, with reports of up to 33% THC. This is the stock material from which all other preparations are derived. Although herbal cannabis and industrial hemp derive from the same species and contain the psychoactive component , they are distinct strains with unique biochemical compositions and uses.

Hemp has lower concentrations of THC and higher concentrations of CBD, which gives lesser psychoactive effects. The Duquenois–Levine test is commonly used as a screening test in the field, but it cannot definitively confirm the presence of cannabis, as a large range of substances have been shown to give false positives.
