It is estimated that 2.7 million Americans are dependent on marijuana.
A Pew Charitable Trust investigation found that marijuana addiction does exist and is growing. While hard numbers are hard to come by, data suggests about 9% of all users become addicted to marijuana (17% among those who start as adolescents). Some treatment centers report increases in those requesting help which may be due to higher concentrations of THC levels. Selective breeding has increased the potency today to 20-30%, up from 2-4% of several decades ago.
PositiveTip: The best policy is to never start, but if you are dependent, get qualified help immediately.
The marijuana industry wants to grow its profits while downplaying the health risks.
After marijuana was legalized in Washington and Colorado, teens perceived it less harmful and use of the drug in this group increased--especially in the younger teens. A large national survey has found even in states without laws allowing recreational use, the perception of the harmfulness of marijuana declined significantly following passage of these laws. While these laws are aimed primarily at adults, they also effect the younger generations.
PositiveTip: Don't let the rising popularity of marijuana blind you from the adverse effects.
Smoking pot precipitates narrowing of brain vessels and probably risk of stroke.
As marijuana (cannabis) use increases, particularly in the young, there is growing concern that younger (under 50) users are at higher risk for ischemic strokes. French research had found regular cannabis users were 3 times as likely to experience intercranial stenosis (narrowing of brain arteries) as non-pot smokers. More research is needed to determine if this finding is causally linked to cannabis use.
PositiveTip: Many think marijuana use is safe, but it does carry serious health risks.
