Abstract

BACKGROUND Marijuana use increases cardiac sympathetic activity within minutes of its use and this effect may begin to decrease as soon as one hour after marijuana use. However, the cardiovascular effects of marijuana use more than an hour after use is poorly characterized. The purpose of the current study is to compare heart rate, a marker of cardiac sympathetic activity, across recent marijuana use groups (never used=63; recent use [in the past 24 hours; subacute] = 13; in the past 7 days, but not in the past 24 hours = 17). Overall, the current sample included 93 African American/Black college students, with a mean age of 20.03 (SD = 2.21). METHODS Participants completed a demographic form, a brief battery of psychological questionnaires, and had their heart rate assessed at baseline. RESULTS Analysis of covariance showed that heart rate was statistically significantly lower in the recent use group (M = 62.38) compared with the non-users group (M = 73.92). This difference persisted before and after statistically adjusting for demographic covariates. CONCLUSIONS These results suggest that there may be a cardiovascular process that occurs when using marijuana that results in a compensatory, reduced heart rate.
近期吸食大麻人群的心率差异。
背景:吸食大麻会在几分钟内增加心脏交感神经活动,而这种影响可能在吸食大麻一小时后开始减弱。然而,使用大麻超过一小时后对心血管的影响尚不清楚。当前研究的目的是比较心率,心脏交感神经活动的标志,在最近的大麻使用组(从未使用=63;最近使用[过去24小时内;亚急性]= 13;在过去7天内,但不在过去24小时内= 17)。总体而言,目前的样本包括93名非裔美国人/黑人大学生,平均年龄为20.03岁(SD = 2.21)。方法参与者完成了一份人口统计表格,一系列简短的心理问卷,并在基线时评估了他们的心率。结果协方差分析显示,近期服药组心率(M = 62.38)明显低于未服药组(M = 73.92)。这种差异在人口统计协变量调整前后仍然存在。结论:这些结果表明,使用大麻时可能发生心血管过程,导致代偿性心率降低。
