How does addiction affect the teen brain?

Worse than adults: The teen brain is still in a period of tremendous growth and that growth predisposes teens towards riskier behaviors. In addition they are at the period in life where peer pressure still has stronger pull. They are at greater risk for developing addiction and doing so at an early age makes it much harder to resolve. The brain becomes wired for the substance and less able to produce naturally.

Addiction: That depends on the substances abused, length of time using them, amounts used, tolerance, genetic susceptibility, general health. The list of substances is indeed endless.

Never good: The most common teen addiction is marijuana abuse. Mj use has been shown to increase risk for schizophrenia, decrease frontal lobe function, & impact language function. Alcohol use has deleterious effects on brain cell growth.Tobacco abuse is inherently harmful to entire body. Opioids impact frontal lobe function, particularly motivation & logic. As dr ali discussed the list is endless. Don't drug.
