The thing is, cannabis is literally a non-lose situation. It's absolutely fine unless you totally abuse it to shit, and if you're half sensible that won't happen.
Studies have failed to really show it as something harmful in the short term, and therefore you may as well give it a try if it's dark, you're deindividuated, and are offered some. Live your life bitches!
Just don't get caught with it obviously. Although to be honest, it's a bit of a joke it hasn't been legalised, especially with the benefits it can bring medically, and especially when considering how harmless it is compared with cigarettes.
