KATV Channel 7 - The Spirit of Arkansas: Addiction Effects

There's new medical evidence that drug use at an early age changes brain development.  New research presented at the annual meeting of the Society for Neuroscience confirms there is long-lasting effects on the brain from substance abuse in the teenage years.  Researchers have found that using marijuana at a young age leads to adult cognitive problems in focus and attention.  Doctors say the teenage brain is only about 80-percent developed. 

Research presented shows a important difference in memory and retention in those kids who drink alcohol and kids who don't.  Through brain imaging, doctors can actually point to the damaged part of the brain in teenagers who drink alcohol.

According to the Society for Neuroscience, more than 4,300 U.S. teens try an illicit drug for the first time every day.  And, for many teens, the drug of choice is prescription drugs or alcohol found right at home.  Many kids say they look to see what they can find around their own house, when they're looking for something to use to get a high. 

Researchers say it is imperative that parents understand the effect of drugs and alcohol on the brain during the teenage years.  They also say it is critical for parents to keep an eye out for signs of trouble.  Last, but not least, they advise parents to keep all alcohol and prescription medication under lock and key, at home.
