Physical Indicators of Drug Addiction

Drug addiction, also known as substance use disorder, can manifest itself in various ways.

One of the first things people often notice are changes in the physical appearance of drug users struggling with addiction.

These changes can range from alterations in body weight to slurred speech, poor coordination and unusual body odours.
