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.
