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.
People who regularly use oxycodone recreationally or at higher than prescribed doses are at even higher risk of severe withdrawal symptoms. The symptoms of oxycodone withdrawal, as with other opioids, may include "anxiety, panic attack, nausea, insomnia, muscle pain, muscle weakness, fevers, and other flu-like symptoms". [51] [52]

[citation needed] The Norman strain of P. somniferum, also developed in Tasmania, produces down to 0.04% morphine but with much higher amounts of thebaine and oripavine, which can be used to synthesise semi-synthetic opioids as well as other drugs like stimulants, emetics, opioid antagonists, anticholinergics, and smooth-muscle agents.
The truth is that it requires years of consistent strength training, plus a mix of genetics and a high-calorie diet, to build a considerable amount of muscle mass that people will notice.
Strength training is far more important for long-term health than people realize, says exercise researcher Dr. Tommy Lundberg. He shares why in a Q&A with CNN.
