Relatively few participants with cannabis use disorders received any type of services, a situation unimproved since NESARC (17). For alcohol use disorders, factors predicting lack of service use include viewing alcohol problems as stigmatized (67) or not serious (68), preference for self-reliance, and beliefs that treatment is ineffective (68). Similar factors appear related to lack of service use for cannabis disorders (31, 69), a topic warranting further investigation. Evidence-based treatments (70–72) are available for cannabis use disorders (33). Public and professional education about treatment efficacy and availability that destigmatizes helpseeking may encourage individuals with cannabis use disorders to seek treatment. Given the increased prevalence of these disorders among U.S. adults (27, 29), provision of such services and public education about treatment appears critically needed.
