Americans Are High On Weed Approximately 288 Million Hours A Week

DISTRICT OF COLUMBIA:  How much do Americans love weed?

According to Jonathan Caulkins, a professor of public policy at Carnegie Mellon University, Americans spend about 15 billion hours a year high on marijuana. He doesn’t believe this is a good number to have arrived at.

Caulkins, author of “Marijuana Legalization: What Everyone Needs To Know,” which will soon be out in a new edition, derived the figure by analyzing the 2013 National Survey on Drug Use and Health, which surveys 70,000 individuals.
