Nine states and the District of Columbia now have legalized marijuana for recreational use. Twenty additional states allow medical marijuana and the numbers are expected to grow. Employers are finding it difficult to comply with both state and federal laws since marijuana still remains a Schedule I illegal drug under the Controlled Substance Act. In April, the Food and Drug Administration (FDA) requested public comments regarding the use of cannabis, while its advisory panel unanimously recommended approval of a cannabis-based medication to treat seizures in children. Senate Minority Leader Chuck Schumer also announced that he would introduce a bill to decriminalize marijuana under federal law, while President Donald Trump promised a Colorado senator that he would support efforts to protect states with legalized marijuana. Currently, however, because of its place as a Schedule I drug, employers are permitted to require a drug-free workplace, but should consider specific laws regarding medical marijuana use.
