Main article: Cannabis (drug)

Cannabis (Marijuana) is a popular psychoactive plant that is often used recreationally. Cannabis is also unique in that it contains a psychoactive substance, THC, which contains no nitrogen and is not an indole, tryptamine, phenethylamine, anticholinergic (deliriant), or a dissociative drug. Cannabis plants tend to vary, with different strains producing dynamic balances of psychoactive cannabinoids (THC, CBD, etc.) that cause different strains to produce markedly different effects, popular strains often being hybrids of both Cannabis sativa and Cannabis indica. Currently, certain universities and research firms are studying the medicinal effects of cannabis. Many jurisdictions have laws regulating (or outright prohibiting) the sale and use of medical cannabis to treat pain, insomnia, and stimulate appetite.



Many of the psychedelic plants contain dimethyltryptamine (DMT), which is either snorted (Virola, Yopo snuffs), smoked, or drunk with MAOIs (Ayahuasca). It cannot simply be eaten as it is not orally active without an MAOI and it needs to be extremely concentrated to be smokable.
