National Centre for Smoking Cessation Training Feb 2016 www.ncsct.co.uk
National Centre for Smoking Cessation Training Stop smoking services should be open to e-cig use in people keen to try them to help then quit This is especially so in those who have tried and failed to quit using licensed stop smoking medicines
60 The Clock Keeps on Ticking Each year delaying quitting..? Each day delaying quitting..?
Take Home Message: Use very brief advice, to keep triggering repeated attempts to stop Offering treatment can spur quit attempts in smokers who might not have seemed motivated Champix + Behavioural Support currently most effective. Single NRT the least If you don t mention smoking, smokers think it s not important, OR that you don t think they can quit!
