so, i've been a crack and heroin user in the uk since 1999 at which time the quality of both drugs were a hell of a lot better than they are now. i know that more people are selling both of the substances mentioned above nowadays and that it has gotten harder to get drugs into the uk, but how has that had such an impact on quality ? i get that this will seem like a stupid qeustion, but it's been annoying me for a couple of years now. anyone have a constructive answer ?
