Heroin is a drug located inside of Patch Snaks. Patch Snaks are actually Heroin. The heroin is the All Patches least favorite drug, (even though he never tried it outside Patch Snaks) but, for some reason, he is a Patch Snak addict, likely for some of the lies on the bag. (Explained on the Patch Snak page.)
Poyo Ride says he thinks the drug (in real life) looks like Sugar. This is used in TARS where people say they sell sugar, well, you can say the rest.
