大美国戒烟日2026年11月19日举行：美国癌症协会号召烟民定下戒烟日
由美国癌症协会（American Cancer Society）主办的年度公共健康倡导活动「大美国戒烟日」（Great American Smokeout）将于2026年11月19日举行——这一天是11月的第三个星期四。活动号召全美烟民在这一天定下戒烟计划，或至少戒烟一天，作为摆脱烟瘾的起点；全美各地的卫生机构同步推广戒烟资源。
大美国戒烟日始于1976年：当年11月18日，美国癌症协会加州分会动员近100万名烟民戒烟一天；1977年活动推向全国，至今已持续近半个世纪，并推动了全美多地的公共场所禁烟规定。美国疾病控制与预防中心（CDC）的数据显示，吸烟与二手烟每年在美国造成超过480,000人死亡，约占全部死亡人数的五分之一，是美国头号可预防死因。
美国癌症协会公布的戒烟收益时间表显示，身体在戒烟后很快开始修复：戒烟20分钟，心率和血压开始下降；12小时，血液中一氧化碳水平恢复正常；2周到3个月，血液循环改善、肺功能提升；1到9个月，咳嗽和气短减轻；1年，冠心病额外风险降至吸烟者的一半；5年，口腔癌、喉癌、食道癌和膀胱癌风险减半，中风风险在2到5年内可降至不吸烟者水平；10年，死于肺癌的风险约为继续吸烟者的一半。
需要帮助的烟民可拨打全国戒烟热线1-800-QUIT-NOW（1-800-784-8669）获得免费辅导，也可向医生咨询经美国食品药品管理局（FDA）批准的尼古丁替代疗法和戒烟药物。CDC与FDA提醒，电子烟未被批准为戒烟产品。专家同时指出，多数成功戒烟者都经历过多次尝试，一次失败并不意味着下一次不会成功。
Great American Smokeout Set for November 19, 2026: Smokers Urged to Pick a Quit Day
The Great American Smokeout, the annual public health campaign organized by the American Cancer Society, will be held on Thursday, November 19, 2026, the third Thursday of November. The event challenges smokers across the United States to make a plan to quit, or to quit for that one day as a first step, and health agencies nationwide promote cessation resources alongside it.
The Smokeout began in 1976, when the California Division of the American Cancer Society persuaded nearly one million smokers to give up cigarettes for a day on November 18; the campaign went nationwide in 1977 and, over nearly five decades, has helped drive community programs and smoke-free laws. According to the Centers for Disease Control and Prevention (CDC), smoking and secondhand smoke cause more than 480,000 deaths in the United States each year, about one in five of all deaths, making it the nation's leading preventable cause of death.
The American Cancer Society's timeline of quitting benefits shows the body begins recovering quickly: 20 minutes after quitting, heart rate and blood pressure drop; at 12 hours, carbon monoxide in the blood returns to normal; within two weeks to three months, circulation improves and lung function increases; at one to nine months, coughing and shortness of breath decrease; at one year, the excess risk of coronary heart disease is cut in half; at five years, the risks of mouth, throat, esophagus and bladder cancers are cut in half, and stroke risk can fall to a non-smoker's within two to five years; at ten years, the risk of dying from lung cancer is about half that of a continuing smoker.
Smokers who want help can call the national quitline at 1-800-QUIT-NOW (1-800-784-8669) for free coaching, or ask a doctor about FDA-approved nicotine replacement therapies and medications. The CDC and FDA note that e-cigarettes are not approved as quit-smoking products. Experts add that most people who quit for good needed several attempts, so a setback does not mean the next try will fail.
