Background and Purpose: Clophedrone (3-chloromethcathinone, 3-CMC) belongs to the methcathinone subclass of ring-substituted cathinones, a prominent group of new psychoactive substances (NPS) present in the illicit drug market. To date no studies have assessed concentrations and acute effects of 3-CMC in humans after self-administration. Experimental Approach: A total of 16 psychostimulant...
Alpha-pyrrolidinopentiophenone (α-PVP) is a commonly consumed analogue of pyrovalerone, a synthetic cathinone with psychostimulant properties similar to those of 3,4-Methylenedioxypyrovalerone (MDPV) and cocaine. Since the pharmacology of α-PVP remains scarcely studied, we aimed to evaluate the acute pharmacological effects and its abuse potential in humans after intranasal administration. We...
Methylone is one of the most common synthetic cathinones popularized as a substitute for 3,4-methylenedioxymethamphetamine (MDMA, midomafetamine) owing to its similar effects among users. Both psychostimulants exhibit similar chemistry (i.e., methylone is a β-keto analog of MDMA) and mechanisms of action. Currently, the pharmacology of methylone remains scarcely explored in humans. Herein, we...
Introduction and objective: Assessing the abuse potential of new substances with central nervous system activity is essential for preventing possible risks of misuse and addiction. The same methodology is recommended for the evaluation of the abuse potential of recreational drugs. This systematic review aims to assess the pharmacological effects related to the abuse potential and...
Introduction: MDMA (3,4-methylenedioxymethamphetamine), a synthetic ring-substituted amphetamine, has become one of the most widely used recreational psychostimulant drugs in the world. Among recreational ecstasy/MDMA users, polydrug use is a phenomenon whose common purpose is to experience the synergistic effect of the combined drugs, moderate MDMA effects, prevent potential toxicity, enhance...
Cannabis is becoming increasingly present in our society. In recent years, the line between the natural (cannabis) and the synthetic (synthetic cannabinoids), the recreational (cannabis) and the medical (pharmaceutical cannabinoids and medical cannabis) has been crossed. In this paper we review some of the novel aspects of cannabis and cannabinoids in relation to their legal situation, changes...
