Banned or Restricted Substances
- Alcohol (Inconsistent)
- Tobacco - importation / posession of tobacco is forbidden except in an authorised Smokatorium, 
- Uncle Ump's Umpty Candy - a confectionary sold in Mega-City One which became known as "the sweet that was too good to eat." Although not a narcotic, it tasted so good that it was impossible to stop eating it once it had been tasted. People who tried to give it up experienced severe withdrawal syndromes. Black market Umpty is made by criminals and those that sell it are known as "Umptybaggers".
- It still remains unclear wheather or not Block Mania should be considered a Drug or a Chemical. In the Comic books its stated that this substance was placed into the Watersuply of mega city one by the East megians during The Atomic wars (2070 -2104). if its true that its just a chemical compound that was placed in the water supply then it remains unclear if the substance was ever produced in pill form and thus be considered a drug.
