Our messages show the real side of quitting, both the good and the bad, to help young people feel motivated, inspired and supported throughout their quitting process. We also send young people evidence-based tips and strategies to quit and stay quit. This is Quitting is tailored based on age (within 13 to 24 years old) and product usage to give teens and young adults appropriate recommendations about quitting.
