I tested positive for marijuana on a DOT/FAA drug test, but recreational use of marijuana is legal in my state. Will my test be cancelled?
No, your test will not be cancelled. Although some states have passed laws that permit the recreational use of marijuana, the Medical Review Officer (MRO) who reviews your test results will not verify your drug test as negative based on recreational use.

Please review the Department of Transportation's Office of Drug and Alcohol Policy and Compliance's position on this issue.

Aside from any state law pertaining to the use of marijuana within a state, it is important to be aware that the FAA's regulation [14 CFR § 120.33(b)], expressly prohibits you from performing a safety-sensitive function for a certificate holder while having a prohibited drug, which includes marijuana and marijuana metabolites, in your system. If you are a pilot, a verified positive drug test result for marijuana on a required DOT/FAA test will make you unqualified to hold an FAA-issued medical certificate.
