How can addiction harm other people?
These effects account for the euphoric or intensely pleasurable feelings that people experience during their initial use of alcohol or other substances, and these feelings motivate people to use those substances again and again, despite the risks for significant harms.

Forming an individualized treatment plan with your healthcare provider’s help is likely to be the most effective approach. When chronic substance use occurs over a long period, these short-term physical effects may cause long-term changes to a person’s brain and body.

Adolescents diagnosed with an SUD show more acute and potentially chronic health problems than teens without SUD. Of the almost two million treatment admissions reported by TEDS,14 less than 40,000 were accounted for by those 60 or over. While many adults “mature out” of heavy drinking and illicit drug use during the second half of life,15 prevalence rates among older adults are also affected by higher mortality rates among drug users.
