WASHINGTON (CBSDC) A new study finds that longtime marijuana use lowers motivation and reward-seeking behavior as the brain produces less dopamine.
In a small sample test, researchers in the United Kingdom scanned the brains of 19 long-term marijuana smokers along with 19 nonusers of the same age and sex, measuring the distribution of chemicals throughout the brain via positron emission tomography.
Marijuana smokers were found to produce less of the feel good chemical dopamine than their counterparts over time.

Um, I’ve never needed any ‘help’ for sexual intercourse. Worst thing about weed is that it’s illegal. But it does have a few other side effects which I avoid, so I’ve stayed away from the stuff. As to the scotch, well, I drank an entire fifth of J&B 8 year old on my 21st birthday. Haven’t been able to even smell the stuff since then. Having spent time as a bartender in college, I am a light social drinker ... I never drink in the dark and tend to get social when I imbibe.
“19 users and 19 non users? I hope they dont call this science”
thanks for that; though in here it likely falls on deaf ears

Trudat!
19 users? 19 non users? That’s not a study, that’s my neighborhood block party!
Gambling at “Rick’s”? “I’m shocked, shocked to find that gambling is going on in here!”

Probably should have compared the dope smoker’s brain scans with mouse brain scans (non-dope smoking mice of course).
“19 users and 19 non users?”
Did you know that 4 out of 5 dentists surveyed recommend sugarless gum? Big study.
“Mau Mau-y Wowie”
That’s the winner!

No sh*t!
Keep ‘em stoned and stupid...Alinsky/ Obozo
You know, this is rather surprising. One would think marijuana smokers would be so much more active and alert.
Wonder how much this stupid information cost us?
