It has been suggested that African-American males, born in the 1970s, initiated the practice of smoking blunts during the rise of the hip-hop subculture in the 1990s. The objective of this study was to determine if other racial/ethnic groups from more recent birth cohorts adopted the practice as well.
Data from seven cross-sectional surveys, the 2004-2010 National Surveys on Drug Use and Health, were aggregated for constructing six five-year birth cohorts (n=297,478), starting with the 1970-1974 cohort. Age-stratified regression models were then developed to test the effect of the interaction between race/ethnicity and birth cohort on the past-year use of blunts.
Fewer differences in the prevalence of past-year blunt smoking were observed between African-Americans and other racial/ethnic groups from more recent birth cohorts. Statistically significant interaction terms in age-stratified models indicated that relative to African-Americans, the odds ratios of blunt smoking were greater in Caucasians and Hispanics born in the1980s compared to those born in the late 1970s. These results were replicated when the sample was limited to past-year cannabis users (n=61,038).
African-Americans, who likely initiated blunt smoking as adolescents/young adults in the 1990s, continued the practice into adulthood. As characterized by other drug eras, the drug became popular over time and expanded into other demographic groups. The additional exposure to tobacco should alert tobacco-control advocates about blunt smokers' risk of developing nicotine dependence.
有人认为，在 20 世纪 90 年代嘻哈亚文化兴起之际，出生于 20 世纪 70 年代的非裔美国男性开始吸食 blunt。本研究旨在确定其他种族/民族群体是否也从更近的出生队列中开始采用这种做法。
对 2004-2010 年全国毒品使用和健康调查的七项横断面调查数据进行汇总，构建了六个五年出生队列（n=297478），起始队列为 1970-1974 年出生队列。然后，建立年龄分层回归模型，以检验种族/民族和出生队列之间相互作用对过去一年使用 blunt 的影响。
在过去一年中，吸食 blunt 的比例在非裔美国人和最近出生队列的其他种族/民族群体之间差异较小。年龄分层模型中的统计学显著交互项表明，与非裔美国人相比，在 20 世纪 80 年代出生的白人和西班牙裔人群，与 20 世纪 70 年代末出生的人群相比，吸食 blunt 的几率比更高。当将样本限制在过去一年吸食大麻的人群（n=61038）中时，结果得到了复制。
作为在 20 世纪 90 年代青少年/年轻人开始吸食 blunt 的群体，非裔美国人将这种行为延续到了成年。正如其他毒品时代的特点一样，这种毒品随着时间的推移变得流行起来，并扩展到了其他人群。额外的烟草暴露应该引起烟草控制倡导者对吸食 blunt 的人群尼古丁依赖风险的关注。
