Edit: to be clear, I am not advocating that anyone use meth. It's a horrible drug that will fuck your life. I do however find its particular properties interesting in the abstract.
As far as the word choice, you are probably right. It’s probsbly better to say “most easily accessible to the DIY community” :)
A bunch of seeds and a pot of compost?
Speaking from experience, fwiw.
I suppose in the states where it’s been decriminalized, you can grow it outdoors and not worry about some of that stuff, but that certainly seems like more work than tossing some Sudafed and whatever else in an empty can and shaking it a bunch.
Again, not advocating anyone try meth. Do not try meth.
...and a location with proper sun. Outdoor-sun-grown weed... that brings back memories.
Cartels can run large labs supplied with drums of industrial chemicals instead of taking the "easy" but difficult-to-scale route that starts with OTC pills. And if they used to be able to turn a profit on smuggling product with a mass-to-value ratio as low as cannabis, they should surely be able to manage the same with methamphetamine.
This line of thinking feels like a hold over from the 80s and the notion of drug pushers.
High school kids aren't going to just start doing meth.
I would guess though that meth (a la Breaking Bad) is too easy to make inside the US for import competition, while heroin has been hit by the dual availability of Pharma delivered Oxy and China delivered Fentanyl/Carfentanil... the combination makes for a bad time in the cartel industry. Of course that makes them more desperate to import other things for pay.
