美国过去一年频繁使用大麻的用户因恶心呕吐症状住院的病例显著增加。根据美国疾病控制与预防中心的报告，从去年10月至今年5月，急诊室对大麻高血压综合征的诊断上升了16%[1]。这一数据来自全国约7,500家医疗机构的统计[1]。
从2023年1月至2025年夏季，累计近200,000例相关症状的患者在急诊室就诊[1]。CDC估计每年有275万美国人患此症[1]。去年10月该疾病获得独立诊断代码后，住院病例出现了显著跳跃，这使长期被低估的问题得以更准确地记录和跟踪[1]。
患者中出现最大增幅的群体包括15至24岁的年轻人、女性青少年、黑人以及美国印第安人和阿拉斯加原住民[1]。CDC研究作者Alana Vivolo-Kantor表示年轻人患病增加是"令人惊讶的发现"[1]。
Hospital emergency departments across the United States have documented a significant increase in cases of cannabis hyperemesis syndrome, a condition causing severe nausea and vomiting among frequent marijuana users.[1] According to the Centers for Disease Control and Prevention, emergency room diagnoses of the syndrome rose 16 percent between October of last year and May of this year.[1] The CDC's analysis drew data from approximately 7,500 medical facilities nationwide and identified nearly 200,000 emergency visits with related symptoms spanning from January 2023 through summer 2025.[1]
The spike in recorded cases reflects both genuine disease incidence and improved diagnostic tracking.[1] A new diagnostic code for cannabis hyperemesis syndrome that took effect in October of last year enabled more accurate recording and monitoring of a condition that had previously been significantly underreported.[1] The CDC estimates that approximately 2.75 million Americans experience this syndrome annually.[1] Certain populations showed the largest increases, including adolescents and young adults aged 15 to 24, female teenagers, Black individuals, and American Indian and Alaska Native populations.[1] Alana Vivolo-Kantor, one of the study's authors at the CDC, described the rise in cases among young people as a "surprising finding."[1]
