It's less "here's a bag of free drugs, wander off and enjoy" and more frequently "yo, wanna do some blow with me?" I'm sure you've encountered SOMETHING like this.

Maybe if you lived in poverty in a housing project where many dealers are competing with each other and moving heroin, crack, meth, and fentanyl to desperate people who want to escape.

I did grow up in relative poverty, though not in a housing project. The area I grew up in, at the time, had lots of Crack but no Meth/Heroin etc. Still, never heard of it.

I'm quite sure it's an urban myth :-)

Wow, the username here really checks out, especially with the misspelling.

"throwaway-burnout" was taken IIRC
