Is 'Reefer Madness' preferable to Drunken Debauchery?

I hear about how awful marijuana is all the time. In health we're told I'm not telling you not to smoke pot, but you'll die if you do!, and I can't even use the bathroom in peace without being bombarded with biased statistics (I'm looking at you, Tinkle Times). Okay, maybe "80% of NT students didn't smoke pot the last time they hung out with their friends," but what if they were with their friends at the mall and didn't have the opportunity to smoke? 

This Pew Research Survey reveals that every demographic (at least the ones they tested) believes that alcohol is more harmful and dangerous to society than marijuana. 

After the disastrous prohibition era of the 1920's, alcohol has been a cultural staple for American social gatherings. Despite its widespread use, however, majority of Americans consider it to be more harmful than marijuana. Even 45% of those who don't believe in its legalization answered that it is less harmful to a person's health than alcohol. Hell, even Obama agrees!

So why, then, is alcohol legal and weed illegal? Alcohol itself has always been accepted by the general population, but propoganda against the use of marijuana has made people demonize it. Just look at Reefer Madness, for example. The film, released in 1936, is filled with unintentionally hilarious scenes of teenagers commiting manslaughter and descending into madness (and having a nervous breakdown while listening to piano music).

We do have to remember that public opinion isn't always scientifically accurate. At one point in history, the popular opinion was that slavery was just fine.

Knowing this, I still can't help but agree with the results of the survey. There are thousands of deaths due to alcohol poisoning every year, but how many deaths due to marijuana overdose have occured? 

Do you agree with the results of the survey? Which do you believe is more dangerous: weed or alcohol?
