I legitimately did this when I was homeless for about a year. Cigarettes were a forum of currency and I always had one in my hat or behind my ear, I would just tell people hey it’s my last one if they asked for it as well

Depends on the person. If it’s just someone that uses a PC for the browser and doesn’t want to learn anything something like popOS or mint would do. If they are ok with learning some Linux/Arch basics, BTRFS + EndeavorOS + KDE is hard to beat and would be my first recommendation

Manjaro bad.

It’s important to make a distinction between drugs that cause substance addiction (alcohol, opioids, tobacco) and things that trigger some people’s behavioral/impulse addictions, Cannabis, food, sugar, porn.

I find it quite odd anyone would have them in the same category, even if you are not or have ever been a durg user.
