Δ9 -tetrahydrocannabinol, the principal active component in Cannabis sativa extracts such as marijuana, participates in cell signalling by binding to cannabinoid CB1 and CB2 receptors on the cell surface. The CB1 receptors are present in both inhibitory
With the increasing legalization of cannabis, understanding the consequences of cannabis use is particularly timely. We examined the association between cannabis use and dependence, prospectively assessed between ages 18-38, and economic and social problems at age 38. We studied participants in the
The present paper summarizes the results of a number of pharmacological studies implicating the cannabinoid CB(1) receptor in the neural circuitry regulating different alcohol-related behaviors in rodents. Specifically, cannabinoid CB(1) receptor antagonists--including the prototype,

In this report, a 60-year old patient with a history of mixed nociceptive and neuropathic chronic pain after successful removal of oral squamous cell cancer is described who received outpatient pain treatment in our clinic. Moreover, the patient presented with a history of alcohol The objectives of the present study were to identify the prevalence of alcohol abuse and marijuana use among First Nations youth living on-reserve, and to identify independent risk indicators associated with these behaviours. Two hundred four students from the Saskatoon Tribal Council (Saskatchewan)
Attenuation of increased endocannabinoid signaling with a CB1R neutral antagonist might offer a new therapeutic direction for treatment of alcohol abuse. We have recently reported that a monohydroxylated metabolite of the synthetic aminoalkylindole cannabinoid JHW-073 (3) exhibits neutral antagonist
BACKGROUND
Estimates of who is most at risk from violence by people with mental illness rest mainly on identified patient samples. This study, without such selection bias, examined the targets of violence committed by young adults with as-yet untreated alcohol dependence, marijuana dependence, or
Alcohol-related blackouts (ARBs) are anterograde amnesias related to heavy alcohol intake seen in about 50% of drinkers. Although a major determinant of ARBs relates to blood alcohol concentrations, additional contributions come from genetic vulnerabilities and possible impacts of cannabis use
OBJECTIVE
This study was designed to separately examine the relations between four fundamental components of negative affect (sadness, fear, guilt, and hostility) and the onset of substance use. An additional goal was to examine the potential mediating roles that these components of negative affect
The relationships between cannabis use frequency with alcohol use, alcohol-related harms, and persistent alcohol use disorder (AUD) in a general population subsample of individuals previously treated for AUD were examined.Secondary analyses of the 2005, Introduction: People with serious mental illness (SMI) use cannabis more than any other illicit drug. Cannabis use is associated with increased psychotic symptoms and is highly comorbid with alcohol use disorders (AUDs). Despite the national trend toward decriminalization, little is known about the
This study examined whether marijuana use was associated with clinically problematic outcomes for patients with depression and alcohol use disorder (AUD). The sample consisted of 307 psychiatry outpatients with mild to severe depression and past 30-day hazardous drinking/drug use, who participated
BACKGROUND
Psychoactive substance abuse, which includes abuse of alcohol and street drugs, is common among first-episode psychosis patients, but the prevalence of cannabis abuse is particularly high. However, there have been very few reported studies concerning the occurrence of psychoactive
The purpose of the present study was to investigate whether cannabis dependent users who met criteria for a secondary diagnosis of alcohol use disorder (AUD) would increase their use of alcohol in response to decreasing their use of marijuana in a behavioral treatment trial for cannabis use disorder
