Okey doke.
You needn't worry. Drugs will never be legalized, so you have little to fear of drugged hordes overrunning your home any time soon.
There's just too much money in it, for both sides of the law. The gangs that control the cities, and the law enforcement that lives off them, will never allow legalization even of things as harmless as pot.
The gangs don't want it because it would kick the legs out from under them and they'd have a lot harder time recruiting new members.
The druggies don't want it because then they would become harder to get and more expensive.
The cops don't want it because then they wouldn't be able to seize houses, cars and other nice toys without due process.
So... it works well for everybody. Nothing will change. No worries.
Huh? That's 100% wrong. It would be easier to get and would be much cheaper.
You could stop right there! What has ever been legalized, besides alcohol a long time ago? Will absinthe ever be legalized? Carrying a nail clipper into an airplane? Serving a hamburger done rare?
