Marijuana is the most widely used illicit drug among drivers, including those seriously and fatally injured in crashes. Research confirms that marijuana use can cause significant short- and long-term impairment, putting users and others on the road at risk of crash and injury. There is no consistent relationship between the blood concentration of ∆9-tetrahydrocannabinol, the primary psychoactive component in marijuana, and driving impairment. There is substantial precedent and support for zero tolerance per se laws for drugs for drivers arrested for suspicion of driving under the influence. Administrative license revocation is another tool currently used in alcohol-impaired driving cases that could be useful for removing drug-impaired drivers from the road. Recommendations are provided for drug testing, including using new oral fluid screening technology and further research on and monitoring of marijuana-impaired driving.","PeriodicalId":188292,"journal":{"name":"Contemporary Health Issues on Marijuana","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116669142","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Rather than relying on a single, key criterion for proof of causation, a collective approach is taken to the question through reviewing studies testing different criteria. Exploration of the psychiatric epidemiology on marijuana reveals trends in early reports that have been confirmed through more detailed studies in recent years and further bolstered by clinical findings. A significant, causal role for marijuana use in chronic psychotic disorders is substantiated by the literature, as well as a strong association with mood disorders and suicidal behaviors. This chapter reinforces the importance of considering marijuana’s mental health impacts when formulating appropriate public health programs and when fashioning drug control policies concerning its legal status.","PeriodicalId":188292,"journal":{"name":"Contemporary Health Issues on Marijuana","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133581211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, the authors find that cannabis has a negative association with neurocognition beyond acute intoxication and that earlier age of onset of regular cannabis use is associated with worse neurocognitive outcomes. The discussion highlights critical relationships between cannabis and brain development, and underlines areas that are incompletely understood and should be further studied to be adequately informed for this era of rapid policy change regarding cannabis regulation.","PeriodicalId":188292,"journal":{"name":"Contemporary Health Issues on Marijuana","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134541424","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The core features of addiction and the DSM CUD diagnosis are described with reference to the prevalence of CUD based on the fourth edition of the DSM, differences between the fourth and fifth editions for the criteria for diagnosis, and DSM-based cannabis symptoms.

If these negative consequences are to be avoided, prevention efforts must focus upstream on childhood and adolescent developmental periods before marijuana use is initiated or has become frequent. Upstream prevention targets factors that predict initiation and escalation of marijuana use, which are often called risk and protective factors. This chapter provides a review of current knowledge about risk and protective factors, with an emphasis on psychosocial variables specific to marijuana, differentiating predictors of marijuana use from predictors of other legal and illegal drugs when possible. The chapter also provides suggestions for future research in light of the rapidly changing legal and community conditions related to access, availability, and norms of marijuana use.","PeriodicalId":188292,"journal":{"name":"Contemporary Health Issues on Marijuana","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133945615","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Whereas regular marijuana smoking is associated with symptoms of acute and chronic bronchitis and evidence of microscopic injury to the cells lining the central airways, the majority of community- or population-based studies in regular smokers of marijuana have not found evidence of clinically significant impairment in lung function in comparison with nonsmokers that would be consistent with COPD. However, very few studies have been conducted in older marijuana smokers in the age range when COPD is generally diagnosed, and few longitudinal studies of change in lung function over time have been carried out in smokers of marijuana. Therefore, firm conclusions regarding the potential risks of marijuana for the development of COPD must await additional studies.","PeriodicalId":188292,"journal":{"name":"Contemporary Health Issues on Marijuana","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133920619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
