Cheong, Yoo Seock

Abstract

BACKGROUND: Among the various brands of herbal cigarettes currently available in Korea, Kumyeoncho is the most popular. However, there is no clinical evidence that these herbal cigarettes are effective in helping smokers quit smoking. This study was performed to determine the long term effectiveness of Kumyeoncho herbal cigarettes.
METHODS
Two hundred smokers, all employees of the same company in Cheonan city, voluntarily participated in this study. They were divided into two random groups: 100 smokers used Kumyencho (herbal cigarettes), and the other 100 smokers used nicotine patches. Between July 2002 and February 2003, the smoking status of all participants was evaluated at one month, three months, and six months, after they stopped using regular cigarettes.
RESULTS
The success rates at 1 month were 54.5% for the Kumyeoncho group and 50.7% for the nicotine patch group (P=0.643). The success rates at 3 month were 41.4% and 39.4%, respectively (P=0.875). And the success rates at 6 month were 38.8% and 35.2%, respectively (P=0.747). Statistical analysis showed that the success rate for the Kumyeoncho group was not less than that for the nicotine patch group in all periods. Thirty-seven cases of adverse effects were reported in the Kumyeoncho GROUP: 25 (25.5%) of nausea, 6 (6.1%) of coughing, 5 (5.1%) of dizziness, and 1 (1.0%) of palpitation; thirty-nine cases of adverse effects were reported for nicotine patch users: 18 (25.4%) of itching, 15 (21.1%) of skin irritation and erythema, 2 (2.8%) of dizziness and headache each, and 1 (1.4%) of nausea and palpitation each.
CONCLUSION
With respect to the short and long term effects of herbal cigarettes, Kumyeoncho is considered similarly effective to nicotine patches.
