Exercise: Cutting Pot Usage 50%

Here's a little gem.  Weed arrests since the 1960's.  According to my research about 1% of users are arrested (from here).  There are probably 100 million or so in the US that have used pot.  Fewer, but not a lot fewer, are regular users.

Pot use has been on the rise since the early 1960s.  Prior to that it was the domain of thugs, crooks and jazz musicians (at least that's what they say)...

Not much surprise here.

What is surprising is the relationship to obesity (from here):

Now this chart goes to 2030 but over all there's a correspondence at least superficially.

But wait, as they say, there's more!

Spark up a doobie and think about this:

Runners World (http://www.runnersworld.com/special-report/the-runners-high) published the following (study here):

"In 2011, researchers at Vanderbilt University in Nashville set a dozen heavy-using pot smokers on treadmills and, over two weeks, had them run ten 30-minute sessions at 60 to 70 percent of their maximum heart rate. The result? A more than 50-percent decrease in sparking up. In London, in 2004, researchers showed that even 10 minutes of moderate exercise dulled the craving for a drink among recently detoxed alcoholics. A 2013 study out of the University of Colorado at Boulder even showed a possible reversal of cognitive brain damage in recovering alcoholics who exercised aerobically."

Hmmm...

I wonder if there is some sort of causal relationship here?

Is it the post smoke munchies or a more insidious affect on the brain's dopamine system?

This extends to cigarettes as well, at least according to the article.

Running is apparently an excellent dopamine replacement system.
