Substance Use

According to the CDC, the majority of adults who meet the criteria for having a substance use disorder started using substances during their teen and young adult years.  Common drugs used by teens include: tobacco, alcohol, marijuana, synthetic marijuana, amphetamines (Adderall), prescription painkillers, inhalants, cough medicine, sedatives, tranquilizers, hallucinogens, MDMA (ecstasy), and salvia.

The more risk factors a person has, the greater the chance that taking drugs can lead to addiction. Risk factors include:

  • Biology – genetics, gender, ethnicity, presence of other mental disorders

  • Environment – peer pressure, lack of parental guidance, physical and sexual abuse

  • Young Age – the earlier drug use begins, the more likely it will progress to addiction due to brain development still occurring

Drugs and the Brain

Signs of Drug Use

According to NIDA, if an adolescent starts behaving differently for no apparent reason it could be a sign they are developing a drug-related problem.  Parents may overlook such signs, believing them to be a normal part of puberty.  Other signs include:
•    A change in friends
•    Carelessness with grooming
•    Decline in academic performance
•    Missing classes or skipping school
•    Loss of interest in favorite activities
•    Changes in eating or sleeping habits
•    Deteriorating relationships with family members and friends

According to NIDA, most drugs affect the brain's reward circuit by flooding it with the chemical messenger dopamine. Surges of dopamine in the reward circuit cause the reinforcement of pleasurable but unhealthy activities, leading people to repeat the behavior again and again.  Over time, the brain adjusts to the excess dopamine, which reduces the high that the person feels compared to the high they felt when first taking the drug—an effect known as tolerance. They might take more of the drug, trying to achieve the same dopamine high.
