Right, I'm putting this here first to get some general opinions and if it eventually gets moved to a biology/medical section, that would be good. Basically there has been a lot of debate between my housemates about whether or not cannabis and marijuana are better for you to consume than alcohol. Now I know nothing about these drugs so my questions are: 1. Is there evidence showing they are no worse than alcohol or even less damaging than alcohol? As many claims by my housemates are that cannabis and marijuana are less damaging to the body and less adictive than alcohol. 2. Do you think they should be classified as illegal? What are your views on the drugs (perhaps even a few more than just those three)? As I say initially, although I would like claims to have evidence behind them I will accept general opinions to get things going and get an overall view of the situation.
