Well our government has once again put media hysteria before science and slapped a ban on mephedrone, miaow miaow, or whatever it is known as.... clearly they have been so impressed with the effect that criminalisation has had on the quantity and safety of consumption of other drugs that it just can't wait for the scientific evidence to deliberate one way or another. It may very well be that this drug is harmful, certainly I wouldn't want to be sticking plant food in my body - but all the evidence of past mistakes would suggest that the act of criminalisation will simply make it more attractive, put the profits up for the black market, and encourage even more dangerous substances to be sold masquerading as mephedrone, or indeed diluting it. ...
Not that I have any confidence that the other lot would have acted any differently.....
