The Controlled Substances Act (CSA) is the statute establishing federal U.S. drug policy under which the manufacture, importation, possession, use, and distribution of certain substances is regulated. It was passed by the 91st United States Congress as Title II of the Comprehensive Drug Abuse Prevention and Control Act of 1970 and signed into law by President Richard Nixon. The Act also served as the national implementing legislation for the Single Convention on Narcotic Drugs.
Propylhexedrine, commonly sold under the brand name Benzedrex, is an alkylamine primarily utilized as a topical nasal decongestant. Its main indications are relief of congestion due to colds, allergies, and allergic rhinitis.
HU-210 is a synthetic cannabinoid that was first synthesized in 1988 from (1R,5S)-myrtenol by a group led by Raphael Mechoulam at the Hebrew University. HU-210 is 100 to 800 times more potent than natural THC from cannabis and has an extended duration of action. HU-210 has a binding affinity of 0.061 nM at CB1 and 0.52 nM at CB2 in cloned human cannabinoid receptors compared to delta-9-THC of 40.7 nM at CB1. HU-210 is the (–)-1,1-dimethylheptyl analog of 11-hydroxy- Δ8- tetrahydrocannabinol; in some references it is called 1,1-dimethylheptyl- 11-hydroxytetrahydrocannabinol. The abbreviation "HU" stands for Hebrew University.
In the United States, the removal of cannabis from Schedule I of the Controlled Substances Act is a proposed legal and administrative change in cannabis-related law at the federal level. It has been proposed repeatedly since 1972. The category is the most tightly restricted category reserved for drugs that have "no currently accepted medical use."
Tiletamine is a dissociative anesthetic and pharmacologically classified as an NMDA receptor antagonist. It is related chemically to ketamine. Tiletamine hydrochloride exists as odorless white crystals.
Zolazepam (Flupyrazapon) is a pyrazolodiazepinone derivative structurally related to the benzodiazepine drugs, which is used as an anaesthetic for a wide range of animals in veterinary medicine. Zolazepam is usually administered in combination with other drugs such as the NMDA antagonist tiletamine or the α2 adrenergic receptor agonist xylazine, depending on what purpose it is being used for. It is around four times the potency of diazepam but it is both water-soluble and un-ionized at physiological pH meaning that its onset is very fast.
Meprodine is an opioid analgesic that is an analogue of pethidine (meperidine). It is closely related to the drug prodine, the only difference being that meprodine has an ethyl group rather than a methyl at the 3-position of the piperidine ring.
Eutylone is a stimulant and empathogenic compound developed in the 1960s, which is classified as a designer drug. It was first reported to the EMCDDA in 2014 and became widespread internationally in 2019-2020 following bans on the related compound ephylone. It is not a natural, but a synthetic cathinone. In 2021, eutylone was the most common cathinone identified by the Drug Enforcement Administration in the United States.
THJ-2201 is an indazole-based synthetic cannabinoid that presumably acts as a potent agonist of the CB1 receptor and has been sold online as a designer drug.
α-Pyrrolidinohexiophenone is a synthetic stimulant drug of the cathinone class developed in the 1960s which has been reported as a novel designer drug.
4-Methylphenethylacetylfentanyl is an opioid analgesic that is an analog of fentanyl and has been sold as a designer drug.
5F-MDMB-PICA (MDMB-5F-PICA) is a designer drug and synthetic cannabinoid. In 2018, it was the fifth-most common synthetic cannabinoid identified in drugs seized by the Drug Enforcement Administration.
5F-EDMB-PINACA is a designer drug and synthetic cannabinoid. In 2018, it was the fourth-most common synthetic cannabinoid identified in drugs seized by the Drug Enforcement Administration.
4F-MDMB-BINACA (also known as MDMB-4F-BINACA, 4F-MDMB-BUTINACA or 4F-ADB) is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family. It has been used as an active ingredient in synthetic cannabis products and sold as a designer drug since late 2018. 4F-MDMB-BINACA is an agonist of the CB1 receptor (EC50 = 7.39 nM), though it is unclear whether it is selective for this target. In December 2019, the UNODC announced scheduling recommendations placing 4F-MDMB-BINACA into Schedule II throughout the world.
Serdexmethylphenidate is a prodrug of dexmethylphenidate created by the pharmaceutical company KemPharm. The compound was first approved by the FDA as one of the active ingredients in Azstarys for the treatment of attention deficit hyperactivity disorder (ADHD) in children, adolescents, and adults in March 2021. Serdexmethylphenidate is a prodrug which has a delayed onset of action and a prolonged duration of effects compared to dexmethylphenidate, its parent compound.
Thenylfentanyl is an analogue of fentanyl where the phenethylamine side-chain has been replaced by a thiophenylmethyl group. It was temporarily scheduled by the Drug Enforcement Administration in 1985, due to fears it would be used as a designer drug. But in 2010 the DEA acknowledged it was essentially inactive. Subsequently, the substance was since deregulated.
