"If you don't ask "why am I here" or "what's this all about" then things get pretty bland pretty quickly."I agree with you. I've always thought the drug problem should be a medical matter handled by doctors and that the law, drug enforcement and cops ought to keep out one's lives when it comes to drugs, but things are never that simple.
The range of drugs is phenomenally broad from essentially harmless to extremely dangerous—some drugs you're never going to OD on to others such as Fentanyl that kills thousands evey year.
How one controls all this and brings order to it in a modern complex society seems overwhelming complex. You can't blame non-drug using people for not wanting intoxicated people driving or in charge of machinery etc. And there are just so many variables involved, the problem seems almost insurmountable.
For example, the effect on those who are around a drug user, family, friends, etc. can be devastating. About a year ago a colleague and friend of mine died from long-term alcohol abuse. What made matters worse he was an organic chemist and he knew what the alcohol was doing to him. We couldn't stop him drinking and many of us tried. Yes, he had the right to do with his life what he wished but at the same time we, his friends and colleagues, had to suffer too by watching him deteriorate.
Essentially, drug taking is not a thing people can do in isolation, drug takers are not decoupled from society, their actions flow-on to the broader community in very complex ways.
I don't have a solution, but I certainly know that banning drugs and treating drug users as degenerates and criminals as we have been doing for over 100 years is stupid and very counterproductive.
