Document Summary
Marijuana is a preparation of leafy material from the cannabis plant that is smoked. Marijuana is classified separately because its effects are varied and complex. Effects it produces in most users are sufficiently different from the effects of depressants, narcotics, and hallucinogens to merit its separate classification. Health canada does not endorse the use of marijuana and is taking the necessary steps to protect public safety while providing reasonable access to marijuana for medical purposes, as ordered by the courts. Originated in asia but now grown worldwide. Grown primarily for its fibres, from which hemp rope is made. Grows as a weed in the us and canada. A lanky plant up to 18 ft high: cannabis indica. Cultivated in many areas of the world. Potency varies depending on plant genetics and environmental conditions: cannabis ruderalis. Primary psychoactive agent in cannabis is delta-0-tetrahydrocannabinol (thc) Thc is concentrated in the resin, most of which is in the flowering tops.
