Don't take it too seriously. My favorite two-panel cartoon, ever:

Girl: Having a joint now and then throughout the day really helps me relax. I mean, without it, I don't know how I would deal with all my problems.

Boy: What problems?

Girl: Are you kidding? I'm behind in my schoolwork, I'm forgetting everything, I'm way too tired, I need to keep borrowing money to pay for this stuff....

Boy: Are you sure that one joint is going to be enough?
