I live in a high cost of living area and I was just telling my coworker, who lives in another state, that I know several people my age (mid-40s) who either still live with their parents or who live with several roommates of the same age, and I don’t blame them a bit because it’s fucking insane out there, dude, and only getting worse.
For me, it totally depends on frequency of their use. Everything in moderation is fine to me (but let’s face it, have you ever known anyone to casually smoke crack once in a while? Some drugs are more dangerous than other).
