You know when you meet someone for the first time and suspect they might get high, but you don't feel comfortable asking them directly? You kind of have to hint at it and know that they'll pick up on the hints if they like to smoke? I find that odd. It's taboo, even though you are essentially asking someone, "Hey, do you like to get happy?" or "Hey, do you enjoy thinking about cool shit, appreciating things more and laughing a lot?" Odd that society feels that has to be hidden.
