Facts About Drug Use

Drug addiction does not occur suddenly. It usually begins by abusing small amounts, and over time progresses into dependency.

Drug abuse takes many different forms, and the signs can vary greatly from person to person. You can begin to tell if someone is using drugs through a few physical, behavioral, and social changes.

Physical Signs of Drug Use

Some of the most telling signs of chronic drug use are physical changes to the body, both externally and internally. Some physical changes associated with drug use include:

  • Eyes that are often red, bloodshot, or glassy
  • Unusually widened or tiny pupils
  • Sudden weight loss or weight gain
  • Constantly runny or bloody nose
  • Change in hygiene habits

Though more difficult to determine, internal changes such as unexpected heart or organ problems can also be signs of chronic drug abuse.

Behavioral changes associated with drug abuse include:

  • Decreased and/or increased appetite
  • Unusual sleep patterns and chronic fatigue
  • Mood swings and general personality changes
  • Decreased interest in his or her personal appearance
  • Depression or anxiety

Some people suffering from drug addiction may begin to shift their social circles or change their daily habits. Different friends, separation from family, and unexpected changes in their activity, work, or school performance are all signs of drug abuse.
