From our allies at the Marijuana Policy Project (MPP): 

MPP's new Potentially Deadly Alcohol and Marijuana Quiz will let you test how much you know about the relative harms of these two substances. If you get a question wrong, the quiz will have you "take a shot" of alcohol. At the end, the quiz calculates your blood alcohol content based on the number of shots you had to take. Ace the quiz and you will be "stone cold sober." But if you flounder, you could wind up dead.

Of course, we don’t recommend really taking shots while you play. We’re serious, though, about the need to educate people on this subject. So after you take the quiz, please spread the word. When you’re done, the quiz makes it easy for you to send an e-mail to friends or post a message on Facebook or Twitter. (The Twitter post will actually be personalized with your quiz result!)

If you can help us get hundreds of thousands of people to take the quiz, we can chip away at the image of marijuana as a "dangerous" drug – an image that has hindered the cause of reform for decades.

You can take the quiz here. Good luck!
