Cannabis Withdrawal Nicolas J. Schlienz and Ryan Vandrey I. D. Montoya, S. R. B. Weiss (eds.), Cannabis Use Disorders, https://doi.org/10.1007/978-3-319-90365-1_11 Introduction Drug withdrawal refers to a constellation of symptoms that occur following abrupt cessation of chronic drug use. Though drug withdrawal can occur from stopping use of medication, it is most often encountered within the context of illicit, non-medicinal, drug use. The withdrawal symptoms that emerge following extended and frequent use of abused drugs are a key feature of what define substance use disorders [4, 85]. Further, there is accumulating neurobiological evidence that withdrawal drives the maintenance of problematic substance misuse through a mechanism of [...]

Trigo, Alexandra Soliman, Lena C. Quilty, Benedikt Fischer, JuÈrgen Rehm, Peter Selby, Allan J. Barnes11¤a, Marilyn A. Huestis, Tony P. George, David L. Streiner, Gregory Staios, Bernard Le Foll PLoS ONE, 2018, 13, (1), e0190768. https://doi.org/10.1371/journal.pone.0190768 Abstract Background The current lack of pharmacological treatments for cannabis use disorder (CUD) warrants novel approaches and further investigation of promising pharmacotherapy. We previously showed that nabiximols (27 mg/ml Δ9-tetrahydrocannabinol (THC)/ 25 mg/ml cannabidiol (CBD), Sativex®) can decrease cannabis withdrawal symptoms. Here, we assessed in a pilot study the [...]

However, it is also a very popular and frequently abused natural hallucinogen. This review summarizes all the past and recent knowledge on psilocybin. It briefly deals with its history, discusses the pharmacokinetics and pharmacodynamics, and compares its action in humans and animals. It attempts to describe the mechanism of psychedelic effects [...]

Reggio Cannabis and Cannabinoid Research, 2017, Volume 2.1, 265-273 DOI: 10.1089/can.2017.0036 Abstract The endocannabinoid system (ECS) has been shown to be of great importance in the regulation of numerous physiological and pathological processes. To date, two Class A G-protein-coupled receptors (GPCRs) have been discovered and validated as the main therapeutic targets of this system: the cannabinoid receptor type 1 (CB1), which is the most abundant neuromodulatory receptor in the brain, and the cannabinoid receptor type 2 (CB2), predominantly found in the immune system among other organs and tissues. Endogenous cannabinoid receptor [...]
