With the legalization of marijuana in some states, companies are adopting new policies on marijuana in the workplace. Even the FBI was reportedly reconsidering its policy against hiring marijuana users. Why the proposed switch? The realization that many successful computer hackers are also marijuana smokers came to light. Excluding marijuana users could be costing the agency some of the most able hackers in an age of spiraling cyber-crime. The public talk about changing FBI policy has led some marijuana users to think that drug use and job security are no longer mutually exclusive \u2013 but that still remains a pretty big leap. Marijuana: State Policy vs. Company Policy Several states have legalized marijuana for both medicinal and recreational use, and the number grows every day. People living in those states may assume that this means they cannot lose their job for smoking pot. However, just because the state grants permission does not mean that employers must also grant permission to use the drug. State law does not abrogate company policies that require employees to remain drug-free. In fact, the Colorado law, which eased prohibitions against marijuana, specifically states that employers retain the right to a drug-free work environment. So just because it is legal in the state does not mean workers are protected on the job if they decide to light up on the weekend. Marijuana in the workplace remains the domain of your employer. The state grants permission, but the boss can still fire you on Monday morning if you don\u2019t pass a drug test. The Problem of Testing for Marijuana in the Workplace To make matters more confusing, neither Washington nor Colorado has yet established a reliable test for measuring marijuana-induced impairment. Most companies use a simple test that shows whether or not marijuana is in a person\u2019s system, not whether or not it is currently at a level to cause impairment. And traces of marijuana can remain in a person\u2019s system for more than a week. That means testing for marijuana in the workplace really means testing for any marijuana exposure in the past week. The kinds of tests used by police officers to measure alcohol impairment in drivers are not yet available. Safety and Legal Concerns of Marijuana Since employers are responsible for workplace safety, they may not be willing to give employees the benefit of the doubt on the issue. And since they are also the ones who would have to deal with potential lawsuits, it isn\u2019t likely that a company that had a drug-free policy before legalization is ready to lift those prohibitions just because the state says it\u2019s okay. In certain fields that involve dangerous work, or where an error could put others at risk, no marijuana in the workplace will likely be tolerated. Marijuana Addiction Marijuana continues to hold a spot on the government\u2019s Schedule 1 list, which means that the government views it as substance with no proven medical benefit and a high risk for addiction. Thus, even though the state may decide to remove penalties for using pot, the addiction risks still remain. Even if your employer holds a loose stance about marijuana in the workplace, an addiction will eventually lead to unacceptable behaviors. The bottom line is that some employers may be willing to overlook marijuana use in places where it\u2019s legal \u2013 but employers are not required to allow employees to use pot. Doing so still involves multiple risks. Just because the state grants permission is no guarantee that a boss will do the same.
