Weed is natural, that is true, but so are various other plants which are poisonous and do, in fact, kill us. Just because something is "found in nature" does not make it good.

However, it should be are choice given what we know about the damage marijuana can cause whether we think smoking it is still a worthy activity. The government restricting us is wrong for this reason.

Don't be stupid, marijuana definately has negative effects- and all smokers have to deal with that fact.
