Text-messaging anti-smoking phrases may be an effective method to motivate a smoker to quit long-term, according to a review of studies looking at anti-smoking interventions.

The review of five studies, which included 9,000 smokers, found that smokers were more likely to quit if sent motivational text messages and quitting advice. In some cases, when participants felt the urge to smoke, interactive messages that required the participant’s response were helpful.
