Cannabis is a plant that grows much like corn or wheat, not some powdered drug produced in a clandestine laboratory. It has many other uses besides being the lowest risk recreational substance used in society. People from middle teens, to seniors, in all walks of life, in every country around the globe. Cannabis produces a feeling of well being, promotes the facilitation of interpersonal behaviour, and reduces aggressive behaviour. In other words, it usually makes people happy, sociable and peaceful.
Cannabis produces no withdrawal symptoms no matter how heavily it is smoked.
For a drug to be physically addictive, it must be reinforcing, produce withdrawal symptoms, and produce tolerance. Marijuana is reinforcing, because it feels good, but it does not do the other two things. Caffeine, nicotine and alcohol are all physically addictive. Cannabis is nontoxic. No deaths from a cannabis overdose have ever been verified.
