God's medicine

Street slang for a potent, high-purity form of heroin, often implying a particularly dangerous or premium-branded batch. The name gained wider cultural recognition through 'The Wire,' where it referred to a premium drug product. The 'blue' may reference the drug's color or simply be an evocative brand-style name used by dealers to signal quality.

Slang for heroin. One of many coded terms used to refer to the drug without using the word itself — a survival strategy in environments where direct naming carries risk. Likely used in specific subcultural circles; less widely documented than terms like 'smack' or 'H.'

An older, euphemistic street name for heroin — the kind of cheerful-sounding label that early 20th-century drug culture used to cloak something dangerous in innocent packaging. The 'joy' half promises pleasure and escape, while 'powder' refers to the drug's physical form. Like many vintage drug slang terms, joy powder has been largely displaced by newer terminology but still appears in historical accounts of addiction, jazz-age drug culture, and noir fiction.

Street slang for crack cocaine, combining the demonic imagery of 'devil' with 'smoke' to capture both the drug's reputation for destroying lives and its method of use — smoked through a pipe. The name reflects the morally charged language that drug culture often uses, either as a warning or as an ironically exciting label. Like many crack cocaine nicknames, it's rooted in the 1980s epidemic period but remains recognizable in contemporary urban slang.
