A biotic suppressant is a drug that reduces or neutralizes the ability of a biotic individual to generate mass effect fields. They are commonly administered to detained biotics as a means of control, but are also sometimes taken voluntarily by biotics that struggle to control their abilities. Long-term use of certain biotic suppressants can cause permanent damage to an individual's biotic capability.
