Cannabis policy of the first Trump administration
The first Donald Trump administration (2017–2021) took positions against marijuana and against the easing of laws regarding marijuana. Although Trump indicated during his 2016 presidential campaign that he favored leaving the issue of legalization of marijuana to the states, his administration subsequently upheld the federal prohibition of cannabis, and Trump's 2021 fiscal budget proposal included removing protections for state medical marijuana laws.
