I didn’t write about Mexico but you are right, they are now growing poppies in their mountains and probably processing it in-country before shipping it into the U.S.
Mexican heroin used to be known as “black mud”. I don’t know what they call it today, but it is bad stuff and the cartels and the street gangs of the Democrat-ruined cities of LA and S.F., Oakland, etc. are the delivery boys.
I sent my kids to private school 12 years ago because I saw what was happening. It worked until 3 years ago and now the private school has 5 dealers. Kids can’t escape it ...they have to know what it does and stay away from it. Most students are clueless.
