Adolescent brains on drugs......

Here is a little bit of information that I found at sciencedaily.com.  It regards the use of Cannabis and how it affects the adolescent brain.
When kids hit adolescence the brain starts to rewire on a very significant level.  The brain connections between the higher-order areas of the cortex start connecting with the deeper brain areas that are related to emotional processing.  This re-connection works with the cognitive functions, such as working memory, decision making, and impulsivity control.  This is why they are having a hard time with getting their life working in a smooth way.  If they use cannabis then this is causing problems with the circuits that are trying to rebuild. 
In one of the studies that was conducted at the University of Montreal, the young people where followed for two years starting in the 7th grade (12 year-olds).  They found that the 19% of the population that were using cannabis had problems with working memory (there go the school grades and doing the chores), inhibitory control, memory recall and perceptual reasoning (what? I didn't get that concept).  This was found to have a increase in the male population..  Along with some of the other studies, there was found a defect in working memory, self control and motivation. 
So if you want your child to succeed, find a way to keep them off of the drugs.

LENS neurofeedback helps the brain to smooth out and work better.  It makes you feel good without the use of other substances and will cost less in the long run.
