Was it the Two Circles?
You draw two circles - one large, one small. The large circle represents your brain now, the small one is your brain on drugs. Got that?

Then - drugs are illegal. The same two circles also represent - small, your arsehole now. Large, your arsehole in prison.

SEE what damage drugs can do!
