>if you wanted to try heroin and if you did it, it would automatically addict you

I have no idea. Lots of people experiment with things and it's no big deal and they insist that must be a universal experience. There's a selection effect. If you try something at 20 and don't survive, you're not around at 40 or 80 to tell people it's no big deal.

When I was young, I enjoyed alcohol a lot, but didn't really struggle giving it up when I had to. Nor did I ever drink until blackout or vomiting, which you know, whether or not it's pathological/alcoholism, is common. I am certain that the level of compulsion is very different for some people.

I have a sibling, who I believe smoked cigarettes off and on but it never became a permanent habit. But a lot of people find them extremely addictive. I never smoked my first one, just because there was never an anticipated reward that seemed worth it. I might have been wrong, or right. Some people seem to get substantial cognitive benefits from nicotine.

Occasionally having a negative reaction to a prescription drug makes me wary of recreational or unregulated stuff, too. Seeing homeopathic stuff in the drug store makes me fearful that a CBD product might be fake too. So when I had wisdom teeth pulled and I was given a bottle of big pink pills (I think it must have been oxycodone/paracetamol based on a quick google) I didn't use a single one.
