Drug Addiction: Signs of Substance Abuse

Drug addiction occurs when the repeated use of an addictive substance produces certain brain changes in a region known as the pleasure center. Even without developing full-blown addiction, regular drug users can develop both clear and relatively subtle indications of substance abuse. Let’s look at some of the potential signs of substance abuse in both adults and teenagers.

Drug Addiction vs. Abuse

Every time you consume an addictive drug, this substance changes the chemical balance inside your pleasure center. In fact, the alteration of chemical levels in this brain area is responsible for the euphoria that often motivates inappropriate drug intake. Over time, your brain will get used to the changes in its chemical makeup. When this adjustment occurs, you must take more of a given drug to feel “high.” At a certain point, your brain will consider a drug-altered state as normal instead of an exception to the rule. This tipping point is the onset of addiction.

The term drug abuse is used in a couple of ways. First, it describes any illicit/illegal or inappropriate consumption of a street drug or a mind-altering medication. Doctors and addiction specialists also use the term more specifically to describe a pattern of excessive drug or medication intake that sets the stage for the eventual development of drug addiction.

Signs of Substance Abuse

There are a broad range of outward signs that may point to the presence of serious substance abuse. Things to look for include:

  • A level of substance intake that frequently leads to clear intoxication
  • Recurring intake of a substance in a setting that presents an obvious danger to the user or other people
  • Reliance on substance use as a main or favored recreational activity
  • Frequent intake of a mind-altering street drug
  • Excessive consumption of a mind-altering medication
  • Association with a social group that uses drugs
  • Job loss as a result of substance use
  • Job absences that stem from substance use
  • Repeated intake of any combination of mind-altering substances (including alcohol)
  • Reliance on substance use for stress relief
  • Intentional hiding of substance use from others
  • Relationship problems caused by substance use
  • Concern from loved ones regarding your level of substance intake
  • Anger or defensiveness when confronted with issues of substance use
  • Social isolation that appears to stem from substance intake
  • Spending money earmarked for bills or other financial obligations on substance use
  • Recurring involvement in substance-related behavior that could result in arrest
  • Recurring run-ins with the law as a result of substance use or substance-related behavior
