Wondering if a mod could make this a sticky (if they feel it may be used often by forum members). Just wanted to post links to the info. so people wouldn't have to search all over every time they wanted to look up which drugs are scheduled by the DEA.
DEA Scheduling, Comprehensive List. This link is to the U.S. Code of Federal Regulations, section 1308 (Schedules Of Controlled Substances). Drugs are specifically categorized e.g. opiates, hallucinogens, etc. It also contains other interesting substance-related info, such as exempted chemicals and prescription products.
Controlled Substance Schedules in a different format. Includes scheduling actions from 1971 to present, showing what was scheduled and when.
DEA Drugs and Chemicals of Concern - self-explanatory, not very useful but included here for the sake of completeness. It does give cause for depression when one's favorite substance shows up there unexpectedly.
