Mood drug

Mood drugs were chemical-releasing cellophane patches used by the New Humans of New Earth from sometime after 5,000,000,023 until 5,000,000,053, typically in the New New York Undercity, including Pharmacytown. They generally gave 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. All in all, they were generally harmless.

A conversation between a Pharmacist and a Pale Woman suggests some of not all of the mood patches come in different degrees of strengths or duration up to at least 43.

One mood drug, however, Bliss, was only found in the upper levels of New New York and extremely addictive. An airborne virus mutated inside, which 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 it eventually began to starve to death, until it became extinct. (DW: Gridlock)


 * Given the near instant effect Sleep and Forget had on the on-screen individuals, it's fair to assume all Mood Drugs take affect that quickly.

Types

 * Happy - When the patch was placed on a person it would put them in a happy mood.
 * Sleep - Once placed on a subject, it will put them to sleep for an indeterminate amount of time.
 * Forget - Forget made people forget certain lengths of time. One of the last patches bought at Pharmacytown was bought by a Pale Woman so that she could forget the disappearance of her parents on the motorway.
 * Retcon also had the power to grant amnesia. It is unclear whether they have the same ingredients as Forget patches.


 * Honesty - When placed on a person, it would not let that person lie and only say the truth.
 * Bliss - An addictive drug which caused a blissful mood and eventually a fatal virus.
