Narrow-leaflet and wide-leaflet drug accessions, southern and eastern Asian hemp accessions, and feral Himalayan populations were assigned to C. An investigation of genetic, morphological, and chemotaxonomic variation among 157 Cannabis accessions of known geographic origin, including fiber, drug, and feral populations showed cannabinoid variation in Cannabis germplasm. Several studies of random amplified polymorphic DNA (RAPD) and other types of genetic markers have been conducted on drug and fiber strains of Cannabis, primarily for plant breeding and forensic purposes. This taxonomic interpretation was embraced by Cannabis aficionados who commonly distinguish narrow-leafed “sativa” strains from wide-leafed “indica” strains. Sativa subspecies into 13 varieties, including four distinct groups within subspecies culta.

A 2022 Gallup poll concluded Americans are smoking more marijuana than cigarettes for the first time.
Some research suggests that the ancient Indo-Iranian drug soma, mentioned in the Vedas, sometimes contained cannabis. Marihuana prensada (‘pressed marijuana’) is a cannabis-derived product widespread among the lower classes of South America, especially in the 1990s. Marijuana or marihuana (herbal cannabis) consists of the dried flowers and fruits and subtending leaves and stems of the female cannabis plant. The added drugs are meant to enhance the psychoactive properties, add to its weight, and increase profitability, despite the increased danger of overdose.d After revisions to cannabis scheduling in the UK, the government moved cannabis back from a class C to a class B drug.
A Quick Take on Cannabis and Its Effects
- These statistics include visits in which the patient was treated for a condition induced by or related to recent cannabis use.
- Native to Central or South Asia, cannabis has been used as a drug for both recreational and entheogenic purposes and in various traditional medicines for centuries.
- The oldest written record of cannabis usage is the Greek historian Herodotus’s reference to the central Eurasian Scythians taking cannabis steam baths.
However, its use medically has gathered some concern, as while certain patients may experience benefits, some medical professionals have said that there is not enough research to determine if the positives outweigh any future negatives. Many marijuana users first come to Das for help coping with something else, like alcohol use disorder. According to the latest version of the National Survey on Drug Use and Health, 7% of all people 12 or older had cannabis use disorder in 2024 and most had a mild form.
Cannabis is a popular recreational drug around the world, only behind alcohol, caffeine, and tobacco. Globally, in 2013, 60,400 kilograms of cannabis were produced legally. Cannabinol (CBN) was the first compound to be isolated from cannabis extract in the late 1800s. In 1545, cannabis spread to the western hemisphere where Spaniards imported it to Chile for its use as fiber.
There is limited research on the health effects delta-8-THC and other intoxicating cannabinoids and related compounds, including delta-10-THC, THC-O-acetate, THCV, THCP, HHC, HHC-O-acetate, HHCP, and CBN. Cannabis sativa L plants containing very small, non-intoxicating amounts of delta-9 THC, which are also called hemp, are mainly used for textile fiber and for their edible seed oils. Cannabis, which some people call marijuana, refers to the dried leaves, flowers, stems, and seeds of the Cannabis sativa L plant. Not all hospital systems and healthcare providers certify medical marijuana in states where it’s legal.

This suggests secondhand cannabis smoke from bongs may present a health risk to non-smokers. At one Colorado medical center following legalization, approximately two percent of ER admissions were classified as cannabis users.
Mental Health Effects
The highest risk of cannabis dependence is found in those with a history of poor academic achievement, deviant behavior in childhood and adolescence, rebelliousness, poor parental relationships, or a parental history of drug and alcohol problems. Few high quality studies have been performed on the long-term effects of cannabis on cognition, and the results were generally inconsistent. Some immediate undesired side effects include a decrease in short-term memory, dry mouth, impaired motor skills, reddening of the eyes, dizziness, feeling tired and vomiting. Acute negative effects may include anxiety and panic, impaired attention and memory, an increased risk of psychotic symptoms,b the inability to think clearly, and an increased risk of accidents.

How to identify signs of cannabis use disorder
It has been suggested that the presence of monoecy can be used to differentiate licit crops of monoecious hemp from illicit drug crops, but sativa strains often produce monoecious individuals, which is possibly as a result of inbreeding. Cannabis also has a long history of being used for medicinal purposes, and as a recreational drug known by several slang terms, such as marijuana, ganja, pot or weed. It is illegal to smoke hash in public, and anyone caught doing so can be arrested and charged with a range of offenses, including drug possession and public nuisance. It’s easy to see why so many people are drawn to the city’s cannabis culture.
What is the active ingredient in marijuana?
Hirata in 1924 that an XY sex-determination system is present. Based on studies of sex reversal in hemp, it was first reported by K. Many models have been proposed to explain sex determination in Cannabis. Dioecious varieties are preferred for drug production, where the fruits (produced by female flowers) are used. As a result of intensive selection in cultivation, Cannabis exhibits many sexual phenotypes that can be described in terms of the ratio of female to male flowers occurring in the individual, or typical in the cultivar.
It’s possible to get addicted to pot. Here’s what to know
In 2021, 35.4% of people aged 18 to 25 (11.8 million people) reported using marijuana in the past year. Marijuana is one of the most used drugs in the United States, particularly among young adults. In other words, marijuana is cannabis, but not all forms of cannabis are marijuana (contain THC). Other names for marijuana include weed, pot and dope. It has several short-term and long-term effects, many of which scientists are still studying.
On 1 January 2013, the first cannabis “club” for private marijuana smoking (no buying or selling, however) was allowed for the first time in Colorado. Simple possession can carry long prison terms in some countries, particularly in East Asia, where the sale of cannabis may lead to a sentence of life in prison or even execution. Many jurisdictions have lessened the penalties for possession of small quantities of cannabis so that it is punished by confiscation and sometimes a fine, rather than imprisonment, focusing more on those who traffic the drug on the black market.

Legalization of cannabis in Canada (as of 17 October 2018update) may help spur private-sector research, especially in terms of diversification of strains. One laboratory at the University of British Columbia found that Jamaican Lamb’s Bread, claimed to be 100% sativa, was in fact almost 100% indica (the opposite strain).
