A list of glanded drugs available to Culture citizens, as mentioned in the novels, together with my interpretation of their effects. Ordered by novel. Some drugs are unnamed, but the effects are described, or at least hinted at.
Note that the capitalization of drug names is inconsistent in the books, although they all appear in italic font. I have retained the original cases here.
