This is just a simplistic model of human behaviour. People assume that the guilty are making these choices independently and the prudent are doing the same. In each case wider societal factors are at play.

I was raised christian and was therefore deeply scared of drugs until age 21, luckily for me by the time I was mature enough to enjoy drugs at around 25 my brain had developed fully and I was able to try MDMA & LSD with positive life-altering consequences. Some of my friends who didnt have the same fear ended up trying hard drugs at far too early an age and became addicted. Not all of them, but at least those who had self-control issues and mild ADHD.

Things often come down to a genetical and circumstantial lottery, the more we do to minimise negative consequences of bad luck and level the playing field the more we will benefit from everyones talent collectively
