“Medical Review Officers will not verify a drug test as negative based upon information that a physician recommended that the employee use “medical marijuana.” Please note that marijuana remains a drug listed in Schedule I of the Controlled Substances Act. It remains unacceptable for any safety‐sensitive employee subject to drug testing under the Department of Transportation’s drug testing regulations to use marijuana.” For more information, please visit the DOT’s website here.
