I think most people who get busted for drugs (personal use type situations) end up in that position secondarily, after stupidly getting caught breaking some other law while in possession of drugs.
Unless you're a high level dealer who's being watched, I don't think a person should have any concern about whether they'll get busted for smoking a joint or something in their basement.

Personally, I think people that use legality as their sole excuse for not doing drugs are actually more afraid/unsure of the drug itself than they are of possible legal consequences. I don't think most functional, intelligent people really think their chances of getting busted are anywhere near as high as let on.
