Someone said :
So, if people were allowed to test their drugs before using them, wouldn't that make class A drugs legal?
There's an important point here. It wouldn't strictly make it legal, but it would carry an implication in some people's minds of tacit approval or tolerance of drug-taking.
And that's at the heart of the debate on providing safer supports for drug addicts and / or recreational drug users. On the one hand, some people think offering needle exchanges and suchlike are really enabling drug use and giving an implied social sanction. Other people say, as Ziggy says, make drug use safer, improve education. Move away from
criminalisation to public health and safety issues.
