Many of the older designer drugs (research chemicals) are structural analogues of psychoactive tryptamines or phenethylamines but there are many other chemically unrelated new psychoactive substances that can be considered part of the designer drug group.
Most substances that were sold as "research chemicals" in this period of time are hallucinogens and bear a chemical resemblance to drugs such as psilocybin and mescaline. As with other hallucinogens, these substances are often taken for the purposes of facilitating spiritual processes, mental reflection or recreation.
U-47700 is an agonist of the μ-opioid receptor (K i 11.1 ± 0.4 nM) and possesses significantly lower affinity for the κ-opioid receptor (K i = 287 ± 24 nM) and δ-opioid receptor (K i = 1220 ± 82 nM). U-47700 is approximately 10-fold more potent than morphine in rats, although the binding of U-47700 is 2–4 times weaker than morphine at ...
All listed chemicals [5] as specified in 21 CFR 1310.02 (a) or (b). This includes supplements which contain a listed chemical, regardless of their dosage form or packaging and regardless of whether the chemical mixture, drug product or dietary supplement is exempt from regulatory controls. For each chemical, its illicit manufacturing use is ...

The opioid epidemic took hold in the U.S. in the 1990s. Percocet, OxyContin and Opana became commonplace wherever chronic pain met a chronic lack of access to quality health care, especially in Appalachia. The Centers for Disease Control and Prevention calls the prescription opioid epidemic the worst of its kind in U.S. history.
This appears to largely be a result of actions of opioid drugs at targets other than the three classic opioid receptors, including the nociceptin receptor, sigma receptor and Toll-like receptor 4, and can be counteracted in animal models by antagonists at these targets such as J-113,397, BD-1047 or (+)-naloxone respectively.
