Mood drug

Mood drugs were chemical-releasing cellophane patches used by the people of New Earth from some time before 5,000,000,023 until 5,000,000,053, typically in the New New York Undercity, including Pharmacytown. They generally produced emotions, such as Happy, although others affected the mind in other ways, such as Sleep, Honesty, Anger and Forget. In the Undercity, they were mainly sold by the pharmacists. They were usually harmless.

One mood drug, however, Bliss, was only found in the upper levels of New New York. It was extremely addictive. An airborne virus mutated in it. This spread and killed the entire population of the upper levels within seven minutes, except the Face of Boe in his life-support tank and Novice Hame, whom Boe surrounded with his smoke. The inhabitants of the Undercity and those in the Motorway survived. With no one to feed on, the virus eventually starved to death and became extinct. (TV: Gridlock)

A conversation between a Pharmacist and a pale woman suggests some if not all of the mood patches came in different degrees of strengths or duration up to at least forty-three.

 * Bliss - An addictive drug which caused a blissful mood; eventually it mutated into a fatal virus.
