Alcohol baaaaad

I hope that the wonderfully-aptly named professor Nutt, in studying the relative effects of alcohol, heroin, crack and other drugs, took into account the fact that more or less anyone can buy alcohol cheaply in the supermarket.   While I agree that other, less legal drugs are by no means impossible to obtain, I believe the process is not quite as simple as dropping in to Tescos for a slab of tinnies.

I venture to suggest that were it either as easy to obtain heroin, or as difficult to obtain alcohol, the results might, just possibly, have been a teensy bit different.
