IMPACTS OF MARIJUANA
on the teenage brain By NICOLE HACKLEY, Prevention Technical Assistance Leader
ately, the topic of marijuana is being brought up in more and more conversations. Federal laws still classify it as a Schedule 1 Drug, meaning it is a substance or chemical with no currently accepted medical use, a high potential for abuse and the ability to create severe psychological and/or physical dependence. As 11 states with recreational marijuana laws have legalized its use for adults over 21, and medicinal marijuana can only be obtained by a medical professional in 33 other states, the perception of risk in using marijuana has decreased among youth-meaning they do not see using the drug as risky. According to the 2018 National Survey on Drug Use and Health (NSDUH), youth ages 12-17 have reported a significant decrease in the perception of harm of weekly marijuana use from 40.6% in 2015 to 34.9% in 2018. Substance abuse prevention professionals work to increase perception of risk of drug use, with the goal of reducing usage rates. They do this because the effects of marijuana on the developing teen brain can have lifetime repercussions. The Substance Abuse and Mental Health Services Administration states that one in six youth who try marijuana will become addicted. Affecting the
hippocampus part of the brain, it impairs attention, memory and concentration. When people begin using marijuana as teenagers, the drug may impair thinking, memory, and learning functions and affect how the brain builds connections between the areas necessary for these functions. At a time when mental health is at the forefront of problems being discussed in America, it is important to point out a clear relationship between youth marijuana use and the increase of major psychiatric episodes. Those who used cannabis more than ten times before age 18 were 2-3 times more likely to be diagnosed with schizophrenia. This statistic alone is disturbing, but is compounded by the knowledge that the average concentration of THC, the active drug in marijuana, has more than tripled from about 4% in 1995 to 13.18% in 2017. Higher doses can lead to acute toxic psychosis, including hallucinations and delusions. Parents and caregivers want their kids to grow up and be the healthiest, best versions of themselves. Marijuana greatly restricts that, so it’s imperative parents talk to their kids about how dangerous this drug is, and that its effects can lead to a lifetime of problems.
