He has made an outstanding contribution to several areas, including the epidemiological, psychopathological and overdose issues relating to the misuse of new/novel psychoactive substances/NPS, the Internet and drugs. Professor Schifano has been the Principal Investigator of six consecutive EU Commission-funded, multi-centre (i.e., 12 EU countries), NPS-based research programmes since 2002. vii brain sciences Editorial Recent Changes in Drug Abuse Scenarios: The New/Novel Psychoactive Substances (NPS) Phenomenon Fabrizio Schifano Psychopharmacology, Drug Misuse and Novel Psychoactive Substances Research Unit, University of Hertfordshire, Hertfordshire AL10 9AB, UK; [email protected] Received: 7 December 2018; Accepted: 9 December 2018; Published: 13 December 2018 Over the last decade, the emergence of a vast range of new/novel/emerging psychoactive substances (NPS) has progressively changed drug market scenarios, which have shifted from the ‘street’ to a ‘virtual’/online environment. Several definitions of NPS are in use, with the term ‘new’ not necessarily referring to new inventions but to substances that have recently been made available, possibly including failed pharmaceuticals or old patents which have been ‘rediscovered’ as ‘recreational’ molecules. Conversely, the term ‘novel’ can refer to something newly created, an old drug that has come back into fashion, or a known NPS molecule being used in an innovative or unusual way and hence presenting a ‘novelty’ appeal (Corkery et al., 2018) [1]. Though misleading, the terms ‘legal highs’ and ‘research chemicals’ have been used alternately to describe these molecules. NPS includes synthetic cannabinoids, cathinone derivatives, psychedelic phenethylamines, novel stimulants, synthetic opioids, tryptamine derivatives, phencyclidine-like dissociatives, piperazines, GABA-A/B receptor agonists, a range of prescribed medications, psychoactive plants/herbs, and a large series of image- and performance-enhancing drugs (IPED) (Schifano et al., 2015) [2]. Overall, users are typically attracted to NPS because of curiosity and the diffusion of social media users’ experiences, easy availability or affordability from online drug shops, legality, intense psychoactive effects, and the likely lack of detection in routine drug screenings (Schifano et al., 2015) [2]. Between 2004 and 2017, some 700–800 examples of NPS were reported by related European and international drug agencies (UNODC, 2018 [3]; EMCDDA, 2018 [4]), with most molecules identified being synthetic cannabinoids, synthetic cathinones, phenethylamine derivatives, and synthetic opioids. However, it could be argued that the NPS scenario is much larger than that outlined by those molecules which have been seized or formally identified by EU and international agencies. Since the online NPS scenario typically predicts the real life NPS scenario (Schifano et al., 2015) [2], identifying what is being discussed online by web-based NPS enthusiasts, or ‘e-psychonauts’ (Orsolini et al., 2015) [5], may well be of interest. With this in mind, a crawling/navigating software (i.e., the ‘NPS.Finder®’) was recently designed by our group. In November 2017, it started to automatically scan, on a 24/7 basis, a vast range of psychonaut web forums for NPS. After a year of operation, it has been possible to estimate that the online/psychonaut web forum NPS scene may include some 4000 different molecules. The most popular examples of NPS mentioned in psychonaut forums have included synthetic cannabimimetics, synthetic opioids, phenethylamines, designer benzodiazepines, and prescribed

Originally developed as a nasal decongestant in the 1950’s, it has recently been re-introduced on the market as a pre-workout and ‘fat-burner’ product but its use remains unregulated. Our work provides the first observational cross-sectional analytic study on Octodrine as a new drug trend and its associated harms after a gap spanning seven decades.

  • Medical Cannabis Q&A
    Medical Cannabis Q&A 1. What is medical cannabis? The term “medical cannabis” is used to describe products derived from the whole cannabis plant or its extracts containing a variety of active cannabinoids and terpenes, which patients take for medical reasons, after interacting with and obtaining authorization from their health care practitioner. 2. What are the main active ingredients? The chemical ingredients of cannabis are called cannabinoids. The two main therapeutic ones are: THC:CBD a. Tetrahydrocannabinol (THC) is a partial agonist of CB1 and CB2 receptors. It is psychoactive and produces the euphoric effect. Each cannabis product will contain THC and CBD, however b. Cannabidiol (CBD) has a weak affinity for CB1 and CB2 receptors and appears the THC: CBD ratio will differ to exert its activity by enhancing the positive effects of the body’s endogenous depending on the product. cannabinoids. 3. Why do patients take it? Medical cannabis may be used to alleviate symptoms for a variety of conditions. It has most commonly been used in neuropathic pain and other chronic pain conditions. There is limited, but developing clinical evidence surrounding its safety and efficacy, and it does not currently have an approved Health Canada indication. 4. How do patients take it? Cannabis can be smoked, vaporized, taken orally, sublingually, topically or rectally. Different routes of administration will result in different pharmacokinetic and pharmacodynamic properties of the drug. 5. Is it possible to develop dependence on medical cannabis? Yes, abrupt discontinuation after long-term use may result in withdrawal symptoms. Additionally, chronic use may result in psychological dependence.

  • Important Information and Warnings About Using Medical Cannabis
    Important information and warnings about using medical cannabis Use of medical cannabis products is experimental Use of medical cannabis products may or may not relieve your symptoms. Existing studies of medical cannabis suggest symptom relief can vary from patient to patient. Side effects are very common. Among the most common side effects are dizziness, fatigue, dry mouth, light- headedness, drowsiness, and nausea. Side effects are usually mild to moderate in severity and usually resolve quickly, but occasionally severe side effects occur. There are unknown each time a patient starts taking any new medication and these unknowns are particularly prominent for medical cannabis, which is not approved for use by the Food and Drug Administration. For most condition, more study of medical cannabis is needed to understand its proper role in comprehensive medical care. Tell all your health care professionals about the medical cannabis you are using Medical cannabis can interfere with other drugs you are taking. Make sure to tell all your health care professionals about the medical cannabis you are taking. Blood levels of other medications might need to be checked, and doses of the medications might need to be adjusted. Warning The following groups are believed to be at increased risk of harm from use of cannabis. Persons in these groups should generally not use medical cannabis • Children, adolescents, and you adults • Women who are pregnant and breastfeeding • Persons with personal or family history of psychotic disorder such as schizophrenia

In the context of a people's Europe, the Commission attaches great Importance to simplifying and clarifying Community law so as to make It clearer and more accessible to the ordinary citizen, thus giving hIm new opportunItIes and the chance to make use of the spec if i c rights It gives him. This aim cannot be achieved so long as numerous provisions that have been amended several times, often QUite substantially, remain scattered, so that they must be sought partly In the original Instrument and partly In later amending ones. Considerable research work, comparing many different Instruments, Is thus needed to Identify the current rules. For this reason a consot tdatton of rules that have freQuently been amended Is essential If Community law Is to be clear and transparent. 2. In Its resolution of 26 November 1974 concerning consolidation of Its acts (1), the Council recommended that those of Its acts which have been amended several times be assembled Into a single text. It stressed that, In the Interests of legal certainty, a genuine legislative consolidation, Involving the repeal of earlier acts, should wherever possible be effected (as Is being done In this case). it conseQuently Invited the Commission to let it have proposals for consol !dation and undertook ·to examine them "as Quickly as possible, whltout bringing Into QUestion, during that consol ldatlon, the substantive solutions contained In the consol !dated texts".

  • DRUGGED DRIVING CONFERENCE Poly Drug
    DRUGGED DRIVING CONFERENCE February 1 – 4, 2021 Phoenix, Arizona Poly Drug Use Presented by: Tom Humphrey Department of Public Safety & Dennis Milius Sergeant, Department of Public Safety Distributed by: ARIZONA PROSECUTING ATTORNEYS’ ADVISORY COUNCIL 3838 N. Central Ave, Suite 850 Phoenix, Arizona 85012 ELIZABETH BURTON ORTIZ EXECUTIVE DIRECTOR Poly Drug Use – Drug Combinations Poly Drug Use: When a person ingests drugs from two or more different drug categories. The body will exhibit a combination of effects. Poly Drug cases can be some of the more difficult cases for the DRE to evaluate. Due to the fact that the defendant has multiple drugs in his/her system, however, there may be less jury appeal for the defendant. Accordingly, they may be easier to prosecute. Note: the crime lab may only quantify some or even none of the drugs. At times the lab cannot test for all of the drugs in the system due to insufficient blood or lack of testing methods. In most cases, this should not prevent us from proceeding on the case. Alcohol is a drug. It is the most common drug used in combination with other drugs. Alcohol combined with cannabis/marijuana is currently the most common drug combination we see in Arizona. Potential Effects of Poly Drug Use Four types of combined effects can, and generally will, occur when two or more drug categories are used together: • Null Effect • Overlapping Effect • Additive Effect • Antagonistic Effect Types of Combined Effects Null Effect The simplest way to explain the null effect is using the phrase: "zero + zero = zero" Example: when a subject consumes one drug, which does not cause HGN, and they ingest another drug, which does not cause HGN, then the officer should not expect to see HGN.

  • Epidemics of HIV, HCV and Syphilis Infection Among Synthetic Drugs
    www.nature.com/scientificreports OPEN Epidemics of HIV, HCV and syphilis infection among synthetic drugs only users, heroin-only users and Received: 7 November 2017 Accepted: 28 March 2018 poly-drug users in Southwest China Published: xx xx xxxx Shu Su1, Limin Mao 2, Jinxian Zhao3, Liang Chen3, Jun Jing4, Feng Cheng4 & Lei Zhang 1,4,5 The number of poly-drug users who mix use heroin and synthetic drugs (SD) is increasing worldwide. The objective of this study is to measure the risk factors for being infected with hepatitis C (HCV), human immunodefciency virus (HIV) and syphilis among SD-only users, heroin-only users and poly- drug users. A cross-sectional study was conducted in 2015 from a national HIV surveillance site in Southwest China, 447 poly-drug, 526 SD-only and 318 heroin-only users were recruited. Poly-drug users have higher drug-use frequency, higher rates of drug-sharing and unsafe sexual acts than other users (p < 0.05). About a third (36.7%) of poly-drug users experienced sexual arousal due to drug efects, which is higher than the rate among other drug users. Poly-drug users had the highest prevalence of HIV (10.5%) and syphilis (3.6%), but heroin-only users had the highest prevalence of HCV (66.0%) (all p < 0.05) among three groups. Logistic regression shows among poly-drug users, having sex following drug consumption and using drugs ≥1/day were the major risk factors for both HIV (Adjusted odds ratio (AOR) = 2.4, 95% CI [1.8–3.4]; 2.3, [1.6–3.1]) and syphilis infection (AOR = 4.1, [2.1–6.9]; 3.9, [1.8–5.4]).
