Abstract

Introduction

Despite increases in the availability, potency, and consumption of cannabis, epidemiological data suggest decreases in the prevalence of cannabis use disorder (CUD) in some groups. Understanding mechanisms for these changes may help improve diagnostic tools for identifying disordered use. This analysis evaluates changes in CUD compared to a substance with comparably stable social and environmental context (alcohol use disorder [AUD]) as well as treatment engagement and need from 2002 to 2019.

Methods

Data were from the National Survey on Drug Use and Health. Outcomes included CUD and AUD symptoms, treatment engagement, and perceived need. Temporal trends and average annual rate of change [AARC] were computed.

Results

Between 2002 and 2019, daily cannabis use prevalence increased by 94 % (AARC=11.68 %), whereas CUD prevalence among those using cannabis daily reduced by 47.9 % (AARC=-10.30 %). Daily alcohol use prevalence decreased by 10.86 % (AARC=-1.90 %), and AUD prevalence among those using alcohol daily reduced by 3.9 % (AARC=-0.67 %). Prevalence of individual 12-month CUD criteria among those using cannabis daily decreased (-13.4 to −59.6 % change; AARC = −2.4 % to −14 %). Among those using cannabis daily, trends in prevalence of individual AUD criteria varied, with some criteria increasing in prevalence and others decreasing (-30.2–24.6 % change; AARC = −5.82–3.7 %). Treatment engagement and perceived need decreased for cannabis, whereas treatment engagement increased and perceived need decreased for alcohol.

Conclusion

These results suggest that CUD and AUD criteria may be determined within the cultural context dictating the definition of harm which has changed for cannabis, but not alcohol, from 2002 to 2019.

2002年至2019年大麻和酒精使用障碍流行趋势的差异。

导读：尽管大麻的可得性、效力和消费量有所增加，但流行病学数据表明，在一些人群中，大麻使用障碍（CUD）的患病率有所下降。了解这些变化的机制可能有助于改进诊断工具，以识别使用不当。该分析评估了2002年至2019年期间，与具有相对稳定的社会和环境背景的物质（酒精使用障碍[AUD]）相比，CUD的变化以及治疗参与和需求。方法：资料来源于全国药物使用与健康调查。结果包括CUD和AUD症状、治疗参与和感知需求。计算了时间趋势和平均年变化率[AARC]。结果：2002年至2019年期间，每日使用大麻的患病率增加了94% (AARC= 11.68%)，而每日使用大麻的CUD患病率降低了47.9% （AARC=- 10.30%）。每天饮酒的患病率下降了10.86% (AARC=- 1.90%)，每天饮酒的AUD患病率下降了3.9% （AARC=- 0.67%）。在每天使用大麻的人群中，个体12个月CUD标准的患病率下降(- 13.4%至- 59.6%的变化；AARC = - 2.4%至- 14%)。在每天使用大麻的人群中，个别AUD标准的流行趋势各不相同，一些标准的流行率增加，另一些标准的流行率下降(-30.2- 24.6%的变化；Aarc = -5.82- 3.7%)。对大麻的治疗参与和感知需求减少，而对酒精的治疗参与增加和感知需求减少。结论：这些结果表明，从2002年到2019年，CUD和AUD标准可能是在决定大麻危害定义的文化背景下确定的，而酒精的危害定义发生了变化。

期刊介绍： Drug and Alcohol Dependence is an international journal devoted to publishing original research, scholarly reviews, commentaries, and policy analyses in the area of drug, alcohol and tobacco use and dependence. Articles range from studies of the chemistry of substances of abuse, their actions at molecular and cellular sites, in vitro and in vivo investigations of their biochemical, pharmacological and behavioural actions, laboratory-based and clinical research in humans, substance abuse treatment and prevention research, and studies employing methods from epidemiology, sociology, and economics.
