True, but the point is, smoking weed can bring out problems people never realised they had before. Maybe not a huge amount of people but it's still more than smoking or alcohol will do. Admittedly alcohol and cigarettes kill far far more people than drugs but to declassify a drug that can leave people mentally scarred without even realising it does that is bad.
I mean people say it should be class c not b, well then, surely fags and booze should be class c or b as well. I personally wouldn't mind if fags were cos i cant give em up without more help.
