You think there’s a “War on Drugs” now, just wait until the government starts getting a cut of the action.
Fedgov has been less heavy-handed with alcohol since Prohibition was repealed, so why would it be any different with mj? Prohibition is the most onerous and intrusive regulatory scheme there is.
Also, I don’t get the point about searches for untaxed pot. People can grow their own in most legalized states. You don’t have to pay a tax on what you grow or carry around with you, provided you’re within the legal amount.
