Well, as far as 'cannabis' goes, what's not to like. No hangover. It's very enjoyable, I don't know why you wouldn't want to smoke it frequently/regularly after trying it once. It would be weird to think "Well, that was really nice but I'm not doing that again." Plus it's not addictive, unlike those other two 'drugs' you mentioned.

I'm wondering what role that word 'suddenly' plays in that sentence. Juices it up, I guess, tries to make it sound scary.

It does have a hangover when you smoke too much, and the stupefying effect that lingers for days in some people is also something to dislike.

But when the drugs you actually need are locked behind a retarded system, you use what you can get.

I don’t see why not. Anyone can get addicted to drugs.
