Legal cocaine?

With Trump's eagerness to control violence from the south, wouldn't the best way to damage their core be to outsource their main source of money?
Now as crazy as it sounds legalizing cocaine wouldn't be as damnging to a political career as it would seem. Logically cocaine and alcohol aren't so different in health damaging effects. If cocaine was legal the tax money we would make would do wonders for the economy and cripple the gangs. Of course fellow republicans might not agree with me this does seem more like a liberal idea but it could work.
