“It’s Just Weed” – Why Marijuana in the Workplace is a Serious Concern

With the growing acceptance and legalization of marijuana across the country, many employees and even some employers have adopted a more relaxed attitude toward its use. A common phrase heard in workplace discussions is: “It’s just weed.” However, when it comes to the workplace, this mindset can be problematic, particularly when safety, productivity, and compliance are on the line.

The Misconception of “It’s Just Weed”

Marijuana is often viewed as a harmless substance, especially compared to other drugs or alcohol. However, in a professional setting, the impact of marijuana use is not harmless. While it may be legal for recreational or medicinal use in certain states, that does not mean it is risk-free—especially in industries where alertness, decision-making, and motor skills are critical.

The Risks of Marijuana in the Workplace

1. Impaired Cognitive Function and Productivity

Unlike alcohol, which leaves the system relatively quickly, a one time use of THC—the active compound in marijuana—can stay in the body for hours or even days. And with regular use – THC accumulates in the body.  THC affects cognitive functions such as:

• Memory and concentration
• Decision-making and problem-solving
• Reaction time and coordination

Even if an employee isn’t visibly high at work, lingering effects can reduce productivity and increase mistakes, especially in high-pressure environments.

2. Workplace Safety Hazards

For jobs that involve operating machinery, driving, or handling hazardous materials, marijuana use poses a safety risks, which can lead to workplace accidents, injuries, and even fatalities. Even in office settings, impaired judgment can cause costly errors or poor decision-making that negatively impacts business operations.

3. Legal and Compliance Issues

While laws vary state to state, in some states like Ohio where marijuana is legal, employers still have the right to enforce a drug-free workplace policy. Many industries, especially those regulated by the Department of Transportation (DOT) or federal contracts, require strict drug-testing policies. Failing to enforce these policies can lead to:

• Legal liability for the company if an impaired employee causes harm
• Loss of contracts and funding due to non-compliance
• Increased insurance costs due to higher workplace risk

Employers need to remember that federal law still classifies marijuana as an illegal substance, and in many cases, this overrides state legalization in workplace policies.

4. Workplace Culture

A workplace that conveys a casual attitude toward marijuana use risks creating a culture of complacency. If employees believe they can show up under the influence without consequences, it may lead to:

• Lower morale among non-using employees who feel unsafe or uncomfortable
• Increased absenteeism and tardiness
• Difficulty enforcing policies on other substances, such as alcohol or prescription misuse

Employers must clearly communicate their stance on marijuana to their employees and be consistent with their policy and procedures.

How Employers Can Address the Issue:

1. Update and Communicate Policies

• Ensure your drug-free workplace policy clearly outlines rules on marijuana use.
• Communicate the consequences of impairment at work, even if marijuana use occurs outside of work hours.

Make sure you understand your state-specific laws regarding these policies.

2. Train Supervisors and Employees

• Teach managers how to recognize signs of impairment and handle situations professionally.
• Provide education to employees on how marijuana and other drugs can affect performance, safety, and employment status.

3. Implement Fair and Consistent Testing

• Ensure all drug testing policies align with state and federal laws.
• Treat all positive test alike with the same corrective action, regardless of what drug(s) were found.

4. Provide Support for Employees

• Offer Employee Assistance Programs (EAPs) for employees struggling with substance use.
• Promote your assistance options and their contact information, including posting information about the services in multiple places where employees can easily see it and access it.

As marijuana’s legal status is changing, attitudes toward marijuana are also changing. More people think that since it is legal, it must be safe – when in fact marijuana is much more potent than it has ever been and is now available in concentrated forms with as much as 40 – 80% THC. The idea that “it’s just weed” downplays the risks it can pose to workplace safety, productivity, and compliance. Employers must take a proactive stance in educating employees, enforcing policies, and ensuring a safe work environment for all.

At the end of the day, the workplace should be a space where employees can perform their best—without the risk of impairment.
