Fresh Lime Alone for Smoking Cessation
キーワード
概要
説明
Smoking is the major preventable cause of chronic medical diseases and death worldwide. Significant efforts led by World Health Organization (WHO) and several countries have been made to help current smokers to quit, particularly in the developing countries, where their smoking rates continued to rise. Clinical practice guidelines were therefore developed to guide all healthcare personnel in those countries to provide treatment for smokers. However, despite that, only a small number of smokers were able to quit successfully. A large number of smokers who are poor and heavily addicted to nicotine remain and have no access to any effective smoking cessation aids. Although there are several effective medications available for smoking cessation nowadays, the high price of them completely keeps poor smokers away from using them. Alternative and cheaper smoking cessation aids are therefore necessary. During the past decade, certain herbal remedies have been introduced in smoking cessation in Thailand. One of them that have been used widely without any supporting evidence is the fresh lime (Citrus aurantifolia), the well-known native citrus to Southeast Asia. It is anecdotally claimed to be effective and safe in smoking cessation. The present study was designed to determine the efficacy and safety of fresh lime as a smoking cessation aid compared with those of nicotine gum.

| Experimental: Fresh lime Those who were randomly assigned to receive fresh lime were instructed to use it every time they began to crave cigarettes and as often as they needed. Fresh lime needed to be washed and cut into several small pieces by 1st cutting each lime into quarters and then each quarter further into 4 pieces. When needed, subjects were told to suck each piece of lime and thereafter chew the lime skin. To maintain freshness, the remaining slices were to be covered with plastic wrap and stored in the refrigerator as soon as possible. All participants in this group had to report the number of fresh lime slices used per day in the self-report card. | |
| Active Comparator: Nicotine gum The dosage of nicotine gum used in this group was primarily based on the participants' FTND scores. Those with FTND score of 4 or above were given 4-mg nicotine gum. The 2-mg gum was assigned only to light smokers. Appropriate gum use by "chew and park" technique was instructed to all subjects in this group. They were advised to use the gum whenever they began to crave a cigarette but not to exceed more than 20 pieces per day. All participants in this group also had to report the total number pieces of gum used per day in the self-report card. Like the lime use group, phone calls were also made every 2-3 days during the initial month of study to remind them of technique and record keeping. |
