You think all the drugs in America are coming overland across the Mexican border?
NO, Only 85%, which is more than enough to End the War on Drugs if it was closed. NEVER GONNA HAPPEN, Way too much Money and Power involved.
You’re delusional.
Marijuana is grown here in the US. Mexican weed is universally despised.
Meth? a lot of meth comes in over the border. a lot more is manufactured in the US.
Cocaine has been flown in and been brought in by boat since the 1970s.
There are a lot of drugs that come over the border from Mexico. They are a tiny amount of what the US consumes.
