The U.S. appears to be on a path toward legalizing cannabis on the alcohol model, which is to say allowing for-profit corporations to produce, sell, and promote its use. Even after national legalization, it will take decades to observe the full effects on industry structure and behavior, or on use and misuse. However, we should not be surprised if after markets have matured and consumption patterns stabilized, legalization increases acute cannabis intoxication in the U.S. by 40 billion hours per year. This increase in use will be the most important cannabis-specific effect of legalization...

BACKGROUND: Cannabis has been used since ancient times to relieve neuropathic pain, to lower intraocular pressure, to increase appetite and finally to decrease nausea and vomiting. The combination of the psychoactive cannabis alkaloid Δ9-tetrahydrocannabinol (THC) with the non-psychotropic alkaloids cannabidiol (CBD) and cannabinol (CBN) demonstrated a higher activity than THC alone. The Italian National Institute of Health sought to establish conditions and indications on how to correctly use nationally produced cannabis to guarantee therapeutic continuity in individuals treated with medical cannabis...

As studies continue to reveal favorable findings for the use of cannabidiol in the management of childhood epilepsy syndromes and other disorders, best practices for the large-scale production of Cannabis are needed for timely product development and research purposes. The processes of two institutions with extensive experience in producing large-scale cannabidiol chemotype Cannabis crops-GW Pharmaceuticals and the University of Mississippi-are described, including breeding, indoor and outdoor growing, harvesting, and extraction methods...

INTRODUCTION: Injection drug use (IDU) is intricately linked to preventive aspects for human immunodeficiency virus from a public health perspective. No large-scale data are yet available for injectable drug use among children and adolescents in India, apart from few anecdotal reports. AIMS AND METHODS: The present paper reports on the profile and substance use pattern of 509 child IDU users, among a total sample of over 4000 children using substances across 100 sites from 27 states and 2 UTs in India...

Cannabis is used widely in the United States, both recreationally and for medical purposes. Current methods for analysis of cannabinoids in human biological specimens rely on complex extraction process and lengthy analysis time. We established a rapid and simple assay for quantification of Δ(9)-tetrahydrocannabinol (THC), cannabidiol (CBD), 11-hydroxy Δ(9)-tetrahydrocannabinol (11-OH THC) and 11-nor-9-carboxy-Δ(9)-tetrahydrocannbinol (THCCOOH) in human plasma by U-HPLC-MS/MS usingΔ9-tetrahydrocannabinol-D3 (THC-D3) as the internal standard...

BACKGROUND: Clinical trials have shown cannabis to be effective in the treatment of some medical conditions and there is mounting public and political pressure to enact laws enabling the use of cannabis for medicinal purposes. To date, 28 United States (U.S.) states and the District of Columbia have enacted medical cannabis laws. This study sought to identify the main issues pertaining to the development of medical cannabis laws in the U.S, including the role of scientific evidence. METHODS: Data were collected from three groups of participants: government officials, lobbyists and medical professionals involved in the medical cannabis debate in five selected states in the U...

Treatment-resistant epilepsy (TRE) affects 30% of epilepsy patients and is associated with severe morbidity and increased mortality. Cannabis-based therapies have been used to treat epilepsy for millennia, but only in the last few years have we begun to collect data from adequately powered placebo-controlled, randomized trials (RCTs) with cannabidiol (CBD), a cannabis derivative. Previously, information was limited to case reports, small series, and surveys reporting on the use of CBD and diverse medical marijuana (MMJ) preparations containing: tetrahydrocannabinol (THC), CBD, and many other cannabinoids in differing combinations...

BACKGROUND: Substance use may increase the risk of non-adherence to antipsychotics, resulting in negative outcomes in patients with psychosis. METHOD: We aimed to quantitatively summarize evidence regarding the effect of cannabis use, the most commonly used illicit drug amongst those with psychosis, on adherence to antipsychotic medication. Studies were identified through a systematic database search. Adopting random-effects models, pooled odds ratios (OR) for risk of non-adherence to antipsychotic medications were calculated comparing: cannabis-users at baseline v...

Medical marijuana is increasingly prescribed as an analgesic for a growing number of indications, amongst which terminal cancer and multiple sclerosis. However, the mechanistic aspects and properties of cannabis remain remarkably poorly characterized. In this study we aimed to investigate the immune-cell modulatory properties of medical cannabis. Healthy volunteers were asked to ingest medical cannabis, and kinome profiling was used to generate comprehensive descriptions of the cannabis challenge on inflammatory signal transduction in the peripheral blood of these volunteers...

In the United States, federal and state laws regarding the medical use of cannabis and cannabinoids are in conflict and have led to confusion among patients, caregivers, and healthcare providers. Currently, cannabis is legal for medical purposes in 50% of the states, and another seventeen states allow products that are high in cannabidiol (CBD) and low in THC (tetrahydrocannabinol) for medical use. Many of these artisanal products are sold in dispensaries or over the internet. However, none of these products has been approved by the Food and Drug Administration (FDA)...

BACKGROUND AND OBJECTIVES: Recent evidence suggests that women may fare worse than men in cannabis trials with pharmacologic interventions. Identifying baseline clinical profiles of treatment-seeking cannabis-dependent adults could inform gender-specific treatment planning and development. METHODS: The current study compared baseline demographic, cannabis use, and psychiatric factors between women (n = 86) and men (n = 216) entering the Achieving Cannabis Cessation-Evaluating N-acetylcysteine Treatment (ACCENT) study, a multi-site, randomized controlled trial conducted within the National Drug Abuse Treatment Clinical Trials Network...

OBJECTIVE: The extent to which specific categories of acute substance use are short-term risk factors, or warning signs, for suicide attempts is unknown. The aim of the current study was to quantify the near-term effects of sole use and co-use of substances on medically attended suicide attempts. METHODS: The current study used a case-crossover design, comparing substance use within the 24 hours prior to a suicide attempt (case day) to the control day, the matched 24 hours the day prior to the case day...

Of all the various treatment options for epilepsy, no other therapy comes close to the polarity that cannabis engenders. The rationale for this reaction is firmly rooted in the social factors that enshroud the use of marijuana for both medical and recreational purposes. In order to best understand how to approach this controversial treatment, it is essential to explore the social, demographic, and historical variables that have led to the current opinions on cannabis therapy and how this has converged on epilepsy treatment...

OBJECTIVES: Drug interactions, poor adherence to medication and high-risk sexual behaviour may occur in individuals with HIV using recreational drugs. Thus, we aimed to assess the prevalence of recreational drugs use and to explore its clinical impact in HIV patients on treatment. METHODS: Observational, cross sectional, study conducted in a 700 bed university hospital, Barcelona, Spain. A total of 208 adults living with HIV on treatment were included. A questionnaire was administered by clinical pharmacists, including evaluation of sociodemographic variables, past 12-month drug consumption, adherence to antiretrovirals (Simplified Medication Adherence Questionnaire) and high-risk sexual behaviour (condomless sex/multiple partners)...

Maternal psychological distress during pregnancy is a potential risk factor for various birth complications. This study aimed to explore psychological factors associated with adverse birth outcomes. Symptoms of psychological distress, individual characteristics, and medical complications were assessed at two time points antenatally in 285 women from Australia and New Zealand; birth outcomes were assessed postpartum, between January 2014 and September 2015. Hierarchical multiple regression analyses were conducted to examine the relation of psychological distress to adverse birth outcomes...
