Since the dawn of human existence we have been putting things into our bodies to see what they do, then repeating be cause we either liked, got addicted, or simply wanted a bigger sample size (yay science). Drugs aren’t even a human phenomenon, cats like catnip, and other animals have been chewing mildly hallucinogenic leaves for millennia. Somewhere in the trail of human history we developed the artificial idea of an acceptable drug, as science developed we were able to categorise them, and more recently the state has taken an interest in substance consumption.
I’m not by any means arguing that many drugs, used in many ways, aren’t harmful to health and society. My core position in that there will never be zero harm as a result of drugs, instead of targeting impractical zero drug futures, it would be more pragmatic, compassionate and successful to think about ways in which we can reduce the harm of drugs. We must recognise the complexity of a human diaspora. No single factor solely relates to the harm caused by drugs. There are no magic theories, that cover the individual and a massive population with equal accuracy, only suggestions that something might help.
