Today there is continued, and in some cases growing, availability of psychoactive substances, including treatments for mental health disorders such as cognitive enhancers, which can enhance or restore brain function, but also 'recreational' drugs such as novel psychoactive substances (NPS). The use of psychoactive drugs has both benefits and risks: whilst new drugs to treat cognitive symptoms in neuropsychiatric or neurodegenerative disorders could have great benefits for many patient groups, the increasing ease of accessibility to recreational NPS and the increasing lifestyle use of cognitive enhancers by healthy people means that the effective management of psychoactive substances will be an issue of increasing importance...

Synthetic Cannabinoids (SC) are the widest and most diffused class of Novel Psychoactive Substances. SC are chemically heterogeneous and structurally dissimilar from delta-9-tetrahydrocannabinol, being full agonists of the endocannabinoid system receptors CB1 and CB2. Desired effects include euphoria, talkativeness, feelings of joy and laughter, relaxation. With respect to cannabis, SC intake may also be associated with quicker arise of the effects, shorter duration of action, and larger levels of hangover...

BACKGROUND: The emergence of new psychoactive substances (NPS), including synthetic cannabinoid receptor agonists (SCRAs) poses novel challenges for drug regulation and public health. Misconceptions of safety and legality, coupled with the fact that NPS are undetectable on routine drugs screens contributes to their popularity. Concerns over the unpredictable toxicity and abuse potential of NPS has led to a variety of legislative responses worldwide. We wish to describe Australian trends in SCRA use, examining the effects of legislative changes on calls to Australia's largest poisons centre...

The psychoactive properties of lysergic acid diethylamide (LSD) have fascinated scientists across disciplines and the exploration of other analogs and derivatives has been motivated by deepening the understanding of ligand-receptor interactions at the molecular level as well as by the search for new therapeutics. Several LSD congeners have appeared on the new psychoactive substances (NPS) market in the form of blotters or powders. Examples include 1-propionyl-LSD (1P-LSD), AL-LAD and LSZ. The absence of analytical data for novel compounds is a frequent challenge encountered in clinical and toxicological investigations...

Electronic cigarettes (e-cigarettes) are increasing in popularity with 19% of UK smokers reporting to have used them. The ability to regulate the evaporation temperature in newer electronic nicotine delivery systems (ENDS) facilitates the potential for use of these devices to 'vape' cannabis, novel psychoactive substances (NPS) and other recreational drugs. Vaping cannabis does have the potential to reduce tobacco use and combustible cannabis/tobacco-related disease, but with over one-third of UK adults reporting life-time use of recreational drugs and increasing e-cigarette uptake in adolescent groups the misuse of these devices poses a serious potential public health risk...

Hundreds of new psychoactive substances (NPS) have emerged in the drug market over the last decade. Few drug surveys in the USA, however, ask about use of NPS, so prevalence and correlates of use are largely unknown. A large portion of NPS use is unintentional or unknown as NPS are common adulterants in drugs like ecstasy/Molly, and most NPS are rapidly eliminated from the body, limiting efficacy of urine, blood and saliva testing. We utilized a novel method of examining prevalence of NPS use in a high-risk population utilizing hair-testing...

This case report details an individual arrested for drug-impaired driving after leaving the scene of multiple motor vehicle collisions and evading police. The driver was examined by a drug recognition expert and failed the drug recognition evaluation. The driver admitted to using cocaine, marijuana, an antidepressant medication and "N-bomb," a novel psychoactive substance that possesses hallucinogenic properties. Toxicological analyses at the Centre of Forensic Sciences' Toronto laboratory revealed only the substance 2-[4-chloro-2,5-dimethoxyphenyl]-N-[(2-methoxyphenyl)methyl]ethanamine (25C-NBOMe) in the accused's urine...

BACKGROUND AND AIMS: There is a growing use of novel psychoactive substances (NPSs) including synthetic cannabinoids. Synthetic cannabinoid products have effects similar to those of natural cannabis but the new synthetic cannabinoids are more potent and dangerous and their use has resulted in various adverse effects. The purpose of the study was to assess whether persistent use of synthetic cannabinoids is associating with impairments of executive function in chronic users. METHODS: A total of 38 synthetic cannabinoids users, 43 recreational cannabis users, and 41 non-user subjects were studied in two centers in Hungary and Israel...

Hallucinogenic phenethylamines such as 2,5-dimethoxyphenethylamines (2C-X) and their N-(2-methoxybenzyl) derivatives (25X-NBOMe) has seen an increase in novel analogues in recent years. These rapidly changing analogues make it difficult for laboratories to rely on traditional targeted screening methods to detect unknown new psychoactive substances (NPS). In this study, twelve 2C-X, six 2,5-dimethoxyamphetamines (DOX) and fourteen 25X-NBOMe derivatives, including two deuterated derivatives (2C-B-d6 and 25I-NBOMe-d9 ), were analysed using ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-QTOF-MS)...

Nonpsychoactive phytocannabinoids (pCBs) from Cannabis sativa may represent novel therapeutic options for cachexia because of their pleiotropic pharmacological activities, including appetite stimulation. We have recently shown that purified cannabigerol (CBG) is a novel appetite stimulant in rats. As standardized extracts from Cannabis chemotypes dominant in one pCB [botanical drug substances (BDSs)] often show greater efficacy and/or potency than purified pCBs, we investigated the effects of a CBG-rich BDS, devoid of psychoactive [INCREMENT]-tetrahydrocannabinol, on feeding behaviour...

Amphetamine and its derivatives gained high popularity on the illegal drug market. In the last few years, a lot of new psychoactive compounds structurally related to amphetamine, such as 4-fluoroamphetamine and 4-fluoromethamphetamine swamped the drug market. They were designed to circumvent prohibition of amphetamine and N-methylamphetamine and are distributed via the Internet. Often, a halogen atom is introduced into the phenyl ring of amphetamine to turn the illegal amphetamine legal. Since amphetamines possess a chiral centre, two enantiomers are available, which might differ in activity...

The NBOMe derivatives are phenethylamines derived from the 2C class of hallucinogens. Only a few human pharmacologic studies have been conducted on these drugs, and several cases of intoxication and deaths have been reported. Presently, NBOMe are not a part of the routine drugs-of-abuse screening procedure for many police forces, and there are no rapid immunoassay screening tests that can detect the presence of those compounds. In this Article, the voltammetric behavior of 25B NBOMe and 25I NBOMe were investigated and their electroanalytical characteristics determined for the first time...
