Does Smoking Marijuana Make You Smarter?

According to an article regarding cannabis and the brain at the website, NORML:

“Preclinical data recently published in the Journal of Clinical Investigation demonstrating that cannabinoids may spur brain cell growth has reignited the international debate regarding the impact of marijuana on the brain…Researchers at the University of Saskatchewan in Saskatoon found that the administration of synthetic cannabinoids in rats stimulated the proliferation of newborn neurons (nerve cells) in the hippocampus region of the brain and significantly reduced measures of anxiety and depression-like behavior.”

NORML’s tag line is “working to reform marijuana laws,” so their articles are going to admittedly not veer far from the message “marijuana is good for you.”

On the other hand, the U.S. Drug Enforcement Agency webpage on marijuana states that habitual use of marijuana can lead to impairment of critical skills related to attention, memory, and learning.

So, who’s right?  Does pot destroy your brain or make it better?  There may be something to the University of Saskatchewan research, but if I have to judge by people I’ve known who are heavy pot smokers, I’d have to say it definitely didn’t make them smart.  Although they weren’t that bright to begin with, so my data may be skewed.

The only thing I do know for certain, is that you should never have Federal Express deliver your marijuana for you.
