Heroin supply disappearing? See what DEA (Katherine Pfaff) says near end of article.
Photo of Eastern Baltimore Health District & ECA area rowhouses I took from the train in early 1980s, looking over the RR track berm and up the hill toward Hopkins Hospital.
Corresponding approximate view in 2019 via Google Earth 3D, without obstruction of weeds and trash on RR berm:
Other parts of our Baltimore ECA Survey’s neighborhoods, also early 1980s:

Time to pull out Frank Zappa’s PSA?
This image of Zappa often appeared with the sideways quotation.

Great example of how ‘synergy’ differs from ‘interaction’
I think this example might be a case of a departure from an ‘inverse interaction on the additive scale’ for people who would give negative signed ratings to (1) rancid sweat, (2) cabbage, and (3) vinegar, and a positive sign on the dark chocolate. In that case, it is a clear departure from additivity and more ‘infra-additivity’ rather than ‘supra-additivity’ (for many people). I happen to like the smell of most vinegar (positive sign on that rating), some cabbage, but not rancid sweat.
