It’s difficult to keep up with America’s rapidly changing marijuana laws, but this knowledge is critical, both for employers and their employees. Employers need to stay on top of things because they want to ensure a safe and productive workplace while complying with employment law. Their employees—who may want to partake in marijuana on their own time, either medically or recreationally—don’t want to risk losing their jobs.
So we’ve created a handy interactive map to show you which states marijuana is legal in. We’ve even broken it down by medical and recreational marijuana. Below, you’ll also find state-specific information and additional resources.
States where medical marijuana is legal
States where recreational marijuana is legal
This should help you to avoid a lot of the myths and misconceptions going around today about the laws regarding marijuana. For example, a lot of people mistakenly believe that drug testing is no longer allowed in places like Denver, Colorado where marijuana has been legalized, but what most don’t realize is that the US Supreme Court has ruled repeatedly that an employer is well within their rights to test their employees for marijuana use. Likewise, many don’t know employers that are regulated by the Department of Transportation, like those found in busy transportation hubs like Atlanta, Georgia, don’t have the option of not testing for marijuana use because of federal DOT drug testing guidelines.
Eighteen states and the District of Columbia currently allow for recreational marijuana use.
- South Dakota
- New Jersey
- New York
In these states, marijuana is regulated and laws are enforced much like those for alcohol. For example, several states provide that only individuals over the age of 21 may buy and possess marijuana. It’s a crime in those states to buy or give marijuana to those under the age of 21. In each of these states, it still remains a crime to drive while impaired by marijuana.
Forty-eight states have legalized some form of medical marijuana. There are extreme variances in the permitted use and amount of medical marijuana even within the states with more liberal regulations.
Some states, such as Connecticut, require patients to register with the state and have one of eleven qualifying conditions and only allow the sale of medical marijuana from a licensed dispensary. Other states are more liberal in their regulation of medical marijuana and simply require a recommendation from a certified physician in order to obtain medical marijuana.
Still, other states, such as North Carolina and Georgia, do not currently allow for the use of medical marijuana but do allow for the limited use of cannabidiol (“CBD oil”).
The only two states that, as of yet, haven’t legalized medical marijuana use in some form are Idaho and Nebraska.
Some states have “decriminalized” marijuana use and possession. Be very wary of this categorization, however, because what may constitute “decriminalized” in one state, resulting in a purely civil penalty or fine, is actually a misdemeanor in another state and may carry with it a permanent mark on your criminal record.
For example, Connecticut imposes a maximum possible fine of $150 for possession of less than half an ounce of marijuana for first-time offenders. This is purely a civil penalty, resulting in no criminal record. Similarly, Maryland has decriminalized small amounts of marijuana. Possession of fewer than 10 grams will constitute a civil offense punishable by a $100 fine for first-time offenders.
North Carolina, is another story entirely. Despite claims that it has “decriminalized” marijuana, the state still counts possession of less than half an ounce of marijuana as a class 3 misdemeanor. Conviction of a class 3 misdemeanor in North Carolina will go on your criminal record.
Employer rights in medical/recreational use states
While employment law has not shifted as dramatically as the drug laws over the years, the Colorado Supreme Court has recently upheld, in Coats v Dish Network, the firing of an employee who legally smoked marijuana. Because marijuana is still illegal under federal law, employers are well within their rights to test for illegal substances, even in states where marijuana is legal for recreational or medicinal purposes.
For instance, the statutes of the State of California specifically provide that employers may still enforce policies that include marijuana screening.
Arguments in favor of including marijuana in workplace drug screening
Those who support the inclusion of marijuana as one of the screened substances in pre-employment drug testing in those states where marijuana is legal for either recreational or medicinal purposes primarily cite safety standards in support of their argument. Safety-sensitive industries such as the trucking, railway, transportation, and aviation industries are also the most federally regulated employers.
Marijuana remains illegal under federal laws. Because these employers are bound by federal regulations and testing is mandatory under these regulations, these employers lack discretion in their drug screening policies.
Other employers, those not bound by the federal regulations, oppose changing their pre-employment drug screening policies because they wish to remain autonomous in dictating their employment policies. Because marijuana is illegal under federal law, they are well within their rights to screen for all illegal substances and they simply choose to exercise their rights.
Another argument in favor of testing is that some studies show that even though an employee may have used a couple of days before work—their reaction times are still slowed down months after their last use. In fields where reaction time is vital, like nursing and emergency care, supporters argue that it’s a life or death type of situation.
Arguments in favor of removing marijuana from workplace drug screening
In states where marijuana is legal for recreational purposes, it’s treated like alcohol under the statutes. However, there’s one major difference between testing for alcohol and marijuana—detection time.
Alcohol disappears from the user’s system several hours after consumption. Marijuana stays in the user’s system and is detectable on tests up to a month or more after the user’s last use.
Those who argue that marijuana should be dropped from pre-employment drug screening in recreational and medicinal use states contend that the test is not a good test for safety purposes because the user may have smoked while off-duty, just as a person who consumed alcohol off-duty but is now completely free from the influence of any impairing substance. Therefore, advocates proclaim that the presence of marijuana in an employment drug screening could be a poor indicator of any workplace safety issues and creates an unwarranted and unnecessary distinction between the marijuana user and the alcohol consumer. Because there is no such distinction in the state’s statute, they argue, no such distinction should exist in pre-employment drug screening.
Changes in workplace drug policies due to changes in drug laws
In cities such as Denver, where marijuana is legal for recreational purposes, many employers—not mandated by the DOT—have simply removed marijuana from the list of drugs for which pre-employment drug screening is required. The reasoning behind this is largely due to widening the applicant pool for available jobs.
In Colorado, there is a less than 3% unemployment rate, meaning there are sometimes more jobs available than employers can fill. Further limiting the pool of available workers is not something some employers are willing to do. The result is that they have altered their drug-screening process to specifically exclude marijuana.
Some employers, those mandated by the federal government, remain bound by its regulations. Therefore they are unable to change their drug-screening policies. It’s because of this that marijuana remains on standard 5 panel, 10 panel, and 12 panel drug tests.
