The Airport Rules and Regulations also prohibit drug possession at Detroit Metro Airport. Michigan law states that it is against the law to possess or intend to possess controlled substances, whether at an airport or any other location. Violations of the law may lead to convictions for any drug offense, which can be a misdemeanor or a felony. The level of an offense will depend on the type and amount of controlled substance that the individual has in their possession. For the worst felony drug offenses, getting caught at the airport could mean life imprisonment and/or a large fine that could go up to $1,000,000.
