I'm Switzerland they had basically two groups of convicted people, the violent and the drug ones. It's sad but true that non violent drug offenders make a major incarcerated group and once in its basically impossible to escape the downward spiral unless one manages to completely get brainwashed change your life to being sober. For example you won't drive a car again anytime soon but the worst thing is the spiral of conviction.
I stopped counting how many fines I've paid for drug related issues, either straight possession or then dumb shit done while high. They convict you to fines if it's personal use only, once they searched and seized all my digital devices and stuff of value like an inherited gold coin I was saving for hard times, just because a fucking police dog signalled on a legal chem bought over ebay, granted I wanted to make GHB but they didn't even get that, they thought it was intended as a cutting agent. Sodium hydroxide, sad lol.
But last time they told me I would get sentenced to therapy if I continued that way and that's Bad, you're bweucskky sentenced to in time in a high security psych ward for years, then every two years or so next evaluation whether you need more in time and most people stay in for years because they rather keep you than allowing somebody to relapse. All with non violent stuff.
