How can I tell if a work colleague is misusing drugs?

Signs of drug misuse include:

  • sudden mood changes;
  • unusual irritability or aggression;
  • confusion;
  • unusual changes in concentration and energy;
  • impaired job performance;
  • being late for work;
  • taking more time off sick;
  • worsening relationships with colleagues or customers; and
  • dishonesty and theft.

Remember that all these could be signs of other problems, including stress.
