The brain controls all the functions of the body. When drugs or alcohol are introduced to the body and get into the brain they interrupt how the brain works and actually change how the brain performs its work. These changes are what lead to compulsive drug use and ultimately addiction.

So what is addiction and can teenagers actually become addicted or dependant on drugs? Addiction is the overwhelming need to have a substance to function on a day to day basis. Yes, teenagers can become addicted. The part of the brain that controls judgment is not fully developed until a person is in their 20’s. Teens are natural risk takers and thrill seekers so they are definitely curious to experiment with drugs.

Drugs are chemicals and different drugs affect the brain in various ways because each drug has a different chemical structure. Some drugs change the way the brain processes information which can either be permanent or last long after a person as stopped using drugs.

Any kind of drug that is abused whether it be nicotine, marijuana, cocaine, alcohol, prescription medication, huffing, methamphetamines, etc. affect the brain’s “reward” circuit which responds to pleasurable experiences by releasing dopamine. Drugs take over this part of the brain and cause a lot of dopamine to be released into the body. This large amount of dopamine in the body is what causes the “high” or euphoria associated with drug abuse.

Continual use of drugs changes how the brain works and alters how a person thinks and also how a person feels without the drugs in his/her body. This contributes to addiction.

Do you think your teen has a drug problem? It is important to get treatment. Often it is better to remove them from their current environment, away from friends that influence their drug abuse, so they can focus on healing.
