There are so few states that have legalized marijuana that the answer to your question is probably yes.
Nevada is one but I don’t think it was, before the election.
The 2016 United States presidential election in Nevada of November 8, 2016 was part of the 2016 General Election, and was won by Hillary Clinton with a 47.92% popular vote plurality over Donald Trump’s 45.50%.
All of Nevada’s 6 electoral votes were assigned to Clinton.
Trump became the first Republican since 1908 to win the presidency without Nevada.
