The program is called "smokefree TXT".
It's a free text messaging service that provides teens with 24-hour encouragement, advice, and tips to quit smoking.
Teens who sign up for the program select a quit date and then the cancer institute sends regularly timed text messages to the person leading up to the date and continuing for six weeks after the date.
The National Cancer Institute said 20 percent of American teens smoke, a number they hope to reduce with the texting campaign.
