Signs and Symptoms of Drug Use

How do you know if someone is using drugs, and why is it important to know? It’s not just the harm can be done to family and friends if an addict is using, there can actually be liability issues if he or she is impaired by drugs while at work. The DOT mandates rigorous drug testing for persons involved in the transportation industry, but any workplace can be adversely affected by drugs.

If you’re a supervisor who is responsible for ensuring a drug-free workplace, a Non-DOT Supervisor Signs & Symptoms Training Course – Drugs & Alcohol can help you to do your job more effectively. If you’re not a supervisor, taking the course might help you earn the position. In the meantime, here are some of the signs and symptoms of drug use as identified by Narconon.

Every illegal drug has different effects, but virtually all drugs will cause:

  • Changes in eye appearance (redness or glassiness)
  • Sudden behavior changes and mood swings
  • Lack of interest in personal grooming
  • Loss of interest in sports, hobbies, and other activities
  • Withdrawal from friends and family
  • Changes in sleeping patterns

This is by no means a comprehensive list of recreational drugs, nor is it a full list of side effects, which can vary from person to person and may depend on the frequency of use or level of addiction. As recreational drug use in the workplace continues to be a problem, there will always be people needed to identify drug users and attempt to get them the help that they need in order to stop endangering themselves and others through the use of illicit substances.
