The motivation behind its exclusion from the CSA was that under the CSA, all optical isomers of listed Schedule II opiates are automatically Schedule II substances.

Opiates and opioids: Available by prescription for pain relief. Commonly used opioids include oxycodone, hydrocodone, codeine, fentanyl, heroin, methadone, and morphine. Opioids have a high potential for addiction and have the ability to induce severe physical withdrawal symptoms upon cessation of frequent use.

While other opioids of recreational use produce only morphine, heroin also leaves 6-MAM, also a psycho-active metabolite.

Bath salts usually contain cathinones, typically methylenedioxypyrovalerone (MDPV, also known as "monkey dust", although this term can refer to MDPHP as well [8]), methylone or mephedrone; however, the chemical composition varies widely [6] [9] and products labeled with the same name may also contain derivatives of pyrovalerone or pipradrol.
