Brolamfetamine (also known as DOB, bromo-DMA, and 4-bromo-2,5-dimethoxyphenylisopropylamine) is one of a vast number of compounds used recreationally to achieve hallucinogenic effects. Brolamfetamine is one of the most potent hallucinogens, with its hallucinogenic potency directly linked to its abuse potential. Brolamfetamine acts as a partial agonist of 5HT2A, 5HT2B, 5HT2C, and TAAR1 receptors, but it’s psychedelic effects are mainly mediated by its agonistic properties at the 5-HT2A receptor. Animal studies have shown physiologic effects including hypertension, tachycardia, hyperpyrexia, pupillary dilatation, and peripheral vasoconstriction. In general, Brolamfetamine having a similar effect to LSD, with slower onset (up to 3–4 h to peak intoxication) and longer duration of effect (up to 36 h). Brolamfetamine is not commonly available, through periods of higher circulation were reported in Australia in 1983, Ireland in 2003, and in Italy in 2015. Brolamphetamine, as well as many other synthetic hallucinogens, are increasingly being sold as LSD. Internationally Brolamfetamine is a Schedule I drug under the Convention on Psychotropic Substances. Due to its selectivity, Brolamfetamine is often used in scientific research when studying the 5-HT2 receptor subfamily.

Normorphine is an opiate analog, specifically the N-demethylated derivative of morphine. It was first described in the 1953 as part of an effort to characterize N-substituted morphine analogs. Normorphine has relatively little opioid activity, but it is a useful intermediate for the production of more potent morphine analogs. It is also a major metabolite of morphine.

Formebolone is an orally active anabolic-androgenic steroid that is included in the list of prohibited substances by the World Anti-Doping Agency. Formebolone was used in Italy and Spain for infants with malnutrition.

Tenocyclidine (TCP) is a dissociative anesthetic drug with psychostimulant and hallucinogenic effects. This drug shows a broad spectrum of pharmacological activity including antidotal effect in organophosphorus compounds poisoning, radioprotective and anticancer effects. It was studied that the antidotal potency could protect acetylcholinesterase (AChE) in the case of organophosphate poisoning. However, the controversial role of TCP in brain protection should be studied further. Tenocyclidine has a high affinity for the N-methyl-D-aspartate (NMDA) receptors. This property allows using of TCP binding (association rate) as a marker of channel opening and thereby permitting measurement of NMDA receptor activation and ligand binding under identical conditions.

Delorazepam is a benzodiazepine with anxiolytic effects. It is a metabolite of the designer drug diclazepam that can be detected in either the serum or urine. Delorazepam can also be produced by enzymatic treatment of lorazepam with β-glucuronidase. It is indicated for the treatment of anxiety, tension and other somatic or psychiatric manifestations associated with anxiety syndrome, insomnia. The side effects and precautions for use of delorazepam are the same as for all benzodiazepines, in particular as regards the development of dependence (mental and physical) and tolerance. Prolonged use may lead to difficulties remembering recent names and events (anterograde amnesia). It has been approved for marketing in Italy.

N,N-Dimethyl-5-Methoxytryptamine (aka 5-MeO-DMT) is a psychedelic of the tryptamine class. It is found in a wide variety of plant species, and a single psychoactive toad species, the Colorado River toad. Like its close relatives DMT and bufotenin (5-HO-DMT), it has been used as an entheogen in South America. It can also be found in the dart poison traditionally used by the Yanoama Indians of Upper Orinoco. It acts as a non-selective serotonin (5-HT) agonist. -MeO-DMT is O-demethylated by polymorphic cytochrome P450 2D6 (CYP2D6) to an active metabolite, bufotenine. 5-MeO-DMT is classified as a controlled substance in China, Australia, Sweden, Turkey, and the USA.

Cyprenorphine is a mixed agonist-antagonist of opioid receptors. In clinical trials, administration of cyprenorphine induced psychotomimetic effects in pre-operative patients.
