Many of them had elaborate theories about changing synthesis or chirality or cutting agents or active impurities. They would even have theories about modern prescription Adderall or prescription opioids being 1/4 as powerful as in the past due to conspiracies by manufacturers.
The drugs may have changed slightly over the years, but the sad reality is that the real change was their accumulated tolerance and long term damage from drug abuse had blunted their response so much that they could barely feel the drugs any more. For some, this blunted reward response carried over to daily life, with depression and a hedonic being pervasive among the long term users.
A sobering reminder that the negative effects of recreational drugs last long after the hangover. I’m seeing an alarming trend of young people reading “harm reduction” material online and assuming they know the full picture of the risks of drug use. Seeing addicts (most of whom assumed they were using intelligently and practicing “harm reduction”) discuss their long term effects is a sad look into the realities of drug use. There is no free lunch.
