Right - I have two issues with this - my first being we really should, if not legalise, at least declassify & decriminalise all drugs - for many reasons.
My second, if we're going to make them illegal & classify them I would ramp the skunk you can buy today as a class B, if not a class A, it's fucking hideous, pernicious shite, I wouldn't want my 15 year old child smoking it thinking it was innocuous. It's not.
