As an increasing number of people underestimate or discount the effects of drugs, drug abuse has skyrocketed.
This makes it more important than ever before for employers to identify the signs of drug abuse and take appropriate action.
Armed with the proper knowledge, employers can reduce or eliminate the impact of drug abuse on employee safety, productivity, or morale.
Fortunately, identifying the signs of drug abuse in the workplace is relatively simple for an attentive employer once you know what to look for. Below are several common signs:
Changes in behavior
There may be a cause for concern if an ordinarily level-headed employee suddenly begins acting irrationally or aggressive. Likewise, a formerly talkative and outgoing employee who suddenly becomes reclusive for no apparent reason would raise a red flag.
Reduced focus/performance
Drugs have a negative effect on mental acuity, so if an employee’s performance rapidly declines, they seem disinterested in their job, or begin making frequent mistakes; it’s a good idea to evaluate them more closely.
Poor hygiene
Employees who are preoccupied with drugs tend to let their normal hygiene standards fall by the way side. Showing up for work with messy hair, dirty, rumpled clothes, or body odor is a common sign of drug abuse.
Frequent absenteeism
Drug use gives abusers a quick and intense high resulting from a rush of endorphins, but when the effects wear off, the abuser suffers a crash that can last from hours to days. This often produces symptoms of depression, fatigue, and aches and pains that cause them to call in sick or simply not show up.
Health issues
When an ordinarily healthy employee has a major change in their health, absent a legitimate medical condition, it could be a sign of drug abuse. This could include rapid weight gain or loss, anxiety, fatigue, nausea, or skin conditions.
