Electronic cigarettes are a safer alternative for smokers who are unable to quit with other treatments. They provide nicotine and a 'smoking experience', without the smoke which causes almost all the devastating health effects of smoking.
E-cigarettes have helped millions of smokers to quit. The UK Royal College of Physicians and many other independent organisations agree that the risk to health from long-term use of e-cigarettes is unlikely to exceed 5% of the harm from smoking tobacco and that they should be promoted as widely as possible as a substitute for smoking.
It is legal in all states to use e-cigarettes with nicotine to assist quitting smoking as long as you have a prescription from a registered doctor.
Many people simply purchase their own device and nicotine and quit with advice from other users. Other smokers need more support and can benefit from combining e-cigarette use with nicotine patches or Champix to boost success rates. I regularly use e-cigarettes as part of an overall treatment plan for smokers who are unable to quit.
