Think this will fit here.

Why are drugs illegal? Because the govt. can't figure out a way to tax it. If they could, it wouldn't have been demonized and outlawed.

Face it, the only way they get revenue is through fines and siezed assets.

As for winning the "War on Drugs". They can't win it because there would go the revenue. And we all understand revenue is something the govt. has to have.
