Cannabis Intoxication

http://www.fishsiestakey.com/fiopre/3428 CannabisBoth cannabis abuse and dependence are recognized in the United States’ Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV)[1] and the International Classification of Diseases, Tenth Revision (ICD-10).[2] The number of individuals with cannabis-related disorders is twice that of any other illicit drug within the United States, [3] as four million people meet the criteria for a lifetime diagnosis of cannabis dependence.[4] Unfortunately, for those who do seek help, relapse rates are comparable to those of other drugs of abuse.[5] From the Department of Medical Biophysics and Nuclear Medicine at Hadassah Medical Organization at Ein Kerem in Jerusalem, A.M. Weinstein and colleague David Gorelick from the National Institute of Drug Abuse discuss treatment options for cannabis dependence in their article “Pharmacological Treatment of Cannabis Dependence.”[6]

watch Cannabis intoxication is recognized in both the DSM-IV1 and the ICD-10.2 It is known to have psychological and behavioral manifestations, such as euphoria, relaxation, increased appetite, and impaired memory and concentration, as well as physical manifestations, like motor incoordination, tachycardia, and orthostatic hypotension.[7] According to Weinstein and Gorelick, the most severe effects, such as anxiety, panic, and psychosis, are best treated with either a benzodiazepine or a second-generation atypical antipsychotic.6 Currently, there are no medicines approved specifically for the treatment of cannabis intoxication; however, several are currently being examined.6

Cannabis Withdrawal Syndrome

Long-Term Cannabis Treatment

Another approach would be the antagonist approach, according to Weinstein and Gorelick.6 This approach uses long-term treatment with a CB1 antagonist, in order to prevent patients from experiencing the pleasurable effects of cannabis use.6 The result is to stop the drug-seeking behavior in patients.6 This has been seen as a successful approach with patients who are dependent upon opiates and are treated with naltrexone.[10] Currently, no antagonists for the CB1 receptor are known.6
