A preparation claimed to help patients to break the habit of smoking has recently been introduced. Material released in the mouth from a chewing gum causes an unpleasant taste when tobacco smoke is inhaled. This claim has been investigated in a double-blind trial on sixty subjects, thirty of whom took the active chewing gum and thirty the placebo chewing gum. The subjects each used one piece of chewing gum four times a day over a period of two weeks. This investigation clearly indicates that the active chewing gum is effective as an anti-smoking preparation, when used over a period of two weeks and the effect is still demonstrable one month later, although to a lesser extent.
最近推出了一种据称能帮助患者戒烟的制剂。当吸入烟草烟雾时，口香糖在口腔中释放出的物质会产生 unpleasant taste 。这一说法在一项针对60名受试者的双盲试验中得到了研究，其中30人服用了活性口香糖，30人服用了安慰剂口香糖。受试者在两周的时间里每天使用一片口香糖，共四次。这项研究清楚地表明，活性口香糖作为一种戒烟制剂，在使用两周的时间里是有效的，而且在一个月后这种效果仍然可以显现，尽管程度较小。
