2010]. This study shows that baclofen significantly decreased self-reported ratings of ‘High’ and ‘Want Marijuana’ but had no impact on cannabis self-administration in a relapse model of cannabis use. There was also a case study of six patients with cannabis and nicotine dependence that shows that baclofen, at a standard dose of 40 mg/day, could reduce the signs and symptoms of cannabis withdrawal and facilitated abstinence [Nanjayya et al. 2010]. In a recent study, Lile and colleagues suggests that GABA-B receptor subtype could be involved in the abuse-related Inhibitors,research,lifescience,medical selleck inhibitor effects of delta-9-THC and that GABA-B receptors may be implicated in cannabinoid-related behaviors

[Lile et al. 2012]. They emphasize that baclofen could enhance the effects of delta-9-THC or produce comparable effects alone, so could decrease some of the symptoms associated with cannabis withdrawal. We hypothesized that baclofen Inhibitors,research,lifescience,medical could be an effective treatment in reducing

the symptoms of cannabis withdrawal and in decreasing craving. Case report Mr P, an administrative executive aged 40, was monitored by our outpatient addiction department during 2012. He had been using cannabis (in herbal form) at home, every evening, for about 15 years with no abstinence of more than 2–3 days. Inhibitors,research,lifescience,medical He used cannabis to reduce symptoms of irritability and severe insomnia. He told us about his inability to stop his cannabis consumption, as well as growing problems at home

and work, which he thought were related to use of the drug. Apart from occasionally drinking alcohol, he Inhibitors,research,lifescience,medical said that he did not consume any other drug or substance. He used to smoke 5 or 6 joints vitamin d between 18:00 and 22:00 at home alone in his den. He met the criteria for cannabis abuse and dependence of DSM-IV and ICD-10, and had no symptoms of other psychopathological illnesses. He acknowledged finding it difficult to stay focused on specific tasks for a long time and sometimes had a hard time keeping up. Neuropsychological assessment Inhibitors,research,lifescience,medical showed no symptoms of attention deficit hyperactivity disorder (ADHD), but found that cognitive performance was impaired for auditory working memory and short-term memory. Dacomitinib He never felt the urge to smoke cannabis at his work place, but tended to consume more at the weekend and on vacation (an average of 8–10 joints per day). Although convinced that his cannabis allowed him to control his impulsivity, to be less irritable and therefore behave better when with the family, he agreed to come for a consultation when forced to by his wife. She could no longer support seeing him remote, without interest in his children when he was at home, preferring to isolate himself and smoke joints in his own corner of the house. He finally recognized that his behavior at home and with his family was directly related to his consumption of cannabis.
