I'm not against it, but I'm against people who believe that it's no side effects what so ever. That it is harmless in any way. Sure cigarettes and alcohol is more harmful, but at least we are willing to understand that it is a side effect that isn't good for us. Weed smokers who are aware of the side effects I'm supporting because he/she knows that it's still not good for them, but do it of own free will. As long as it don't take over their lives of course
