The use of cannabis with various forms of exercise (e.g., running) has received increased media attention in recent years, contradicting the popular stereotype that cannabis is associated with sedentary behavior. Although cross-sectional evidence suggests a positive association between cannabis use and exercise engagement, to date, the effects of cannabis on exercise remain unclear. The present within-subjects crossover study compared participants' experiences of running after use of legal market cannabis (cannabis run) to running without cannabis (non-cannabis run) in a real-world setting. Participants (=49) were cannabis users between the ages of 21 and 49 years (mean=30.82, standard deviation [SD]=6.21). The majority of participants were male (61.5%) and non-Hispanic White (81.6%). Participants (=49) ran an average of 3.88 miles (SD=2.28) during their cannabis and non-cannabis runs. Although participants ran an average of 31 seconds/mile slower during their cannabis run, this difference was not statistically significant (=0.12). Participants reported experiencing (1) less negative affect (=0.03), (2) greater feelings of positive affect (<0.001), tranquility (=0.004), enjoyment (=0.004), and dissociation (=0.001), and (3) more runner's high symptoms (<0.001) during their cannabis (vs. non-cannabis) runs. Participants also reported lower pain levels after their cannabis (vs. non-cannabis) run (=0.03). Perceived exertion did not differ between runs (=0.33). Cannabis form, cannabinoid content, and feelings of "high" were largely unrelated to participants' experience of exercise while under the influence of cannabis. Results suggest that acute cannabis use may be associated with a more positive exercise experience among regular cannabis users. Research using varied methodologies, a range of exercise modalities, and diverse populations is needed to establish the long-term harms and benefits associated with this behavior, as well as the generalizability of these findings to other populations and settings.
近年来，各种形式的运动（如跑步）与大麻的使用受到了媒体的更多关注，这与大麻与久坐行为相关的普遍刻板印象相矛盾。尽管横断面证据表明大麻使用与运动参与之间存在正相关，但迄今为止，大麻对运动的影响仍不清楚。本研究采用真实环境下的自身对照交叉设计，比较了大麻使用者在使用合法大麻（大麻运动）后和不使用大麻（非大麻运动）时的跑步体验。参与者（=49）为年龄在 21 至 49 岁之间的大麻使用者（平均年龄=30.82，标准差[SD]=6.21）。大多数参与者为男性（61.5%）和非西班牙裔白人（81.6%）。参与者（=49）在大麻和非大麻运动时平均跑步 3.88 英里（SD=2.28）。虽然参与者在大麻运动时平均每英里慢 31 秒，但这一差异无统计学意义（=0.12）。参与者报告称，在大麻（vs. 非大麻）运动时，他们经历了（1）较少的负性情绪（=0.03），（2）更大的正性情绪（<0.001）、平静感（=0.004）、享受感（=0.004）和脱联感（=0.001），以及（3）更多的跑步者快感症状（<0.001）。参与者在大麻（vs. 非大麻）运动后还报告了较低的疼痛水平（=0.03）。两次运动之间的感知用力程度没有差异（=0.33）。大麻形式、大麻素含量和“高”的感觉与参与者在大麻影响下运动的体验基本无关。结果表明，急性大麻使用可能与经常使用大麻的人群中更积极的运动体验有关。需要使用不同的方法学、各种运动方式和不同的人群来开展研究，以确定这种行为的长期危害和益处，以及这些发现对其他人群和环境的普遍性。
