Drug Use in the Workplace, Risks, and Support for Addiction

Drug use in the workplace is a growing concern that affects employee safety, job performance, and organizational productivity. It involves the use or influence of illicit drugs, prescription drug misuse, or alcohol consumption by employees during work hours or while on company property.

In many cases, employees arrive at work already impaired, leading to serious safety risks and legal consequences. Addressing workplace substance abuse is crucial—not just from a productivity standpoint, but also from a health and addiction recovery perspective.

Common Substances Involved

The most common substances linked to workplace drug use include,

  • alcohol,
  • cannabis,
  • cocaine,
  • opioids (such as oxycodone and fentanyl),
  • amphetamines (like Adderall and meth), and
  • sedative medications, particularly benzodiazepines.

Often, individuals struggling with addiction or substance use disorders turn to these substances to cope with high stress, anxiety, burnout, or other mental health challenges. In some industries, access to drugs is easier—especially in healthcare or construction settings.

Reports indicate that about 3 in 10 (33%) construction workers and managers in safety-sensitive positions, and 2 in 10 (18%) construction workers and managers in non-safety-sensitive positions, reported consuming alcohol or other drugs within two hours before or during work, or being hungover, intoxicated or feeling high while at work.

Warning Signs

Drug use in the workplace and addiction can be difficult to detect. Warning signs may include

  • frequent absenteeism,
  • lateness,
  • mood swings,
  • sudden changes in appearance or hygiene.

It often includes,

  • decreased productivity,
  • poor concentration, and
  • workplace accidents.

These red flags may signal an underlying substance use issue that requires professional addiction treatment or intervention.

Impacts on the Workplace

The consequences of substance abuse in the workplace are serious. Safety is compromised, particularly in environments that involve heavy machinery, driving, or hazardous materials. Drug and alcohol impairment can lead to on-the-job injuries, legal liability for employers, and diminished team morale.

Productivity often suffers as employees miss work, make mistakes, or fail to meet deadlines. Co-workers may feel overwhelmed or unsafe, leading to further stress and a toxic work environment.

Some sectors are especially vulnerable to workplace addiction, including the oil and gas industry, transportation, warehousing, and hospitality (such as restaurants and bars). These industries tend to involve long hours, physical demands, and high-pressure environments, all of which can increase the risk of substance misuse.

Prevention and Response

To address drug use in the workplace and support employees dealing with addiction, organizations should implement clear drug and alcohol policies. They should provide education on substance use disorders and promote mental wellness. Drug testing policies—such as pre-employment, random, and post-incident testing—may be necessary in safety-sensitive jobs.

Employers should also offer access to Employee Assistance Programs (EAPs) or refer employees to reputable private drug rehab centers or addiction treatment facilities.

Supervisor training is key to identifying early signs of substance use and guiding employees toward help. Creating a workplace culture that supports recovery, mental health, and healthy coping strategies can reduce the risk of relapse and improve long-term outcomes.

The results include better employees, higher productivity and group cooperation.

Legal Considerations

In Canada and other regions, addiction is legally recognized as a disability under human rights laws. Employers have a duty to accommodate employees who are seeking help for a substance abuse.

This should be done in such a way as not to cause undue hardship or compromise workplace safety. Understanding these legal obligations and offering compassionate support can lead to better recovery outcomes and a safer workplace for all.

In conclusion

Ultimately, tackling drug use in the workplace is not just about discipline—it’s about prevention, education, and access to addiction recovery resources.

By fostering a supportive environment and connecting employees to professional addiction help, companies can play a meaningful role in addressing substance use disorders and promoting long-term recovery.
