For those who want to quit smoking, a new study suggests text messages help. ABC News reports smokers who use a popular texting program to quit, are more than twice as likely as others to be successful. In a recent study more than 500 smokers were followed for 6 months. Among those using the program Text2Quit 11 percent managed to kick the habit. Users could send a text that said "crave" and get motivational messages at no cost. Among those not getting the text messages the success rate was just 5 percent. Participants submitted saliva tests to prove their success or failure. The findings in the American Journal of Preventive Medicine.
