Just to play devil's advocate here, what if we compared two countries: one where the citizens didn't partake in ANY recreational drug use, and one where the citizens were allowed to delve into as many drugs as they pleased. Which do you think would have a more productive economy, have more jobs, and innovate more science and technological inventions?

From the standpoint of the individual, obviously no-one wants the government telling them what to do. But from the standpoint of the government, citizens getting high all the time is no way to maintain a country.
