Marijuana, also known as cannabis, weed, pot, or ganja, is a psychoactive drug derived from the Cannabis plant. 🪴
It is typically composed of the dried leaves, flowers, stems, and seeds of the plant, most commonly from the species Cannabis sativa, but also from Cannabis indica and, more rarely, Cannabis ruderalis[1][8].
Legally, "marijuana" refers specifically to plant parts with more than 0.3% THC by dry weight—this distinguishes it from hemp, which has very low THC and is not psychoactive[9].
Marijuana is used recreationally, for some medical purposes, and has an extensive history as a traditional medicine and for spiritual purposes in different cultures[1][8].
In summary: Marijuana is a psychoactive drug from the Cannabis plant, most known for THC, and is used for recreational, medical, and other purposes. It comes with notable mental and physical effects, and a wide variety of methods for consumption.[1][2][8]
In summary: Marijuana is statistically less dangerous (in terms of public health costs and addiction) than alcohol or tobacco, but poses unique risks—particularly for young users, who are more susceptible to long-term cognitive and psychiatric effects.[1][2][5][8][3]
