Substance use disorder (or addiction) is a psychiatric disorder in humans. In this condition, people uncontrollably consume a substance (legal or illegal drugs or medicines) despite adverse consequences. Excessive use of the substance by a person interferes with their normal functioning at school, at home or at work. These addictive substances include recreational or illegal drugs, tobacco, alcohol, and even some prescription drugs.

Initially, a person may start using a particular substance for pleasure, such as experiencing something for the first time or to manage symptoms, such as pain (as seen in opioid abuse). Over time, the use of the substance can increase so much that they become dependent on it.

Not everyone who participates in activities such as drinking or smoking develops a substance use disorder. The exact cause of substance use disorders remains unknown. However, studies show that people who have peers and family members with attitudes or behaviors that encourage substance use and who inherit related genes from their parents are more likely to develop the disease.

Many of those who develop substance abuse disorder already suffer from depression, attention deficit disorder, post-traumatic stress disorder, or some other psychiatric problem.

A stressful lifestyle and low self-esteem can also lead to addiction.

How do you recognize someone with a substance use disorder?

If someone close to you has a substance use disorder, you may notice one or more of the signs and symptoms, including

  • Have a strong desire to use the substance several times a day
  • Ensure there is an adequate supply of the substance
  • Get agitated if they can’t find the substance when the urge is felt
  • Need more medicine to produce the same effect
  • Suffering from withdrawal symptoms after stopping the substance
  • Be prepared to do anything (even criminal activity) to get the drug in case there is no money to buy it
  • Engaging in risky behavior while under the influence of the substance
  • Adopting secret behavior to hide drug use
  • Feeling powerless in multiple attempts to stop using substances
  • Show episodes of violence
  • Continue to use the substance even when they know it affects their daily life and responsibilities
  • Neglect their appearance
  • Avoiding social gatherings and other recreational activities due to substance use

Besides these symptoms, you may also notice other signs in the person depending on the substance. For example, marijuana and hashish can cause red eyes, slow reaction, and paranoid thoughts.
