SMOKERS can be "breathalysed" to measure their body's level of toxic gas at a Huddersfield pharmacy.
No Smoking Day next week will see the Co-op chemist in Market Street, Milnsbridge, hosting a smokerlyzer machine to measure the amount of carbon monoxide in breath.
Carbon monoxide is tasteless but starves the body of vital oxygen, putting extra strain on the heart.
Smokers wanting to give up the habit are offered a free breath test and consultation.
Liz Colling, of Co-operative Group Pharmacy, said: "Many smokers try to give up for No Smoking Day.
"But to have a good chance of success it is very important to find the best method to suit each person.
"As well as using the smokerlyzer to measure carbon monoxide, we can discuss the smokers' habits to identify the best option for them and offer counselling to help them quit."
Anyone wanting to stop smoking is urged to:
* Complete a smoker's diary to learn when you smoke and set out a plan for stopping.
* Solve potential problems before they happen, such as taking up exercise to thwart weight gain.
* Avoid situations where you may be tempted to smoke.
* Dispose of all smoking accessories such as lighers, ashtrays and of course, cigarettes.
* If you do slip-up, try again.
Smokers wanting to quit can get bags of help from the NHS.
Advice, information and counselling is available on the health service in the run-up to national No Smoking Day on March 10 and afterwards.
Patricia Hodgson, co-ordinator of the Huddersfield Smoking Advice Service, said: "Many smokers think they will be able to quit with willpower alone, but probably don't realise that nicotine is as addictive as heroin.
"In order to be successful in quitting, it is important to prepare for your quit day and have a plan for how you will cope with difficult days.
Ms Hodgson said:
"I'd advise smokers to contact their local NHS Stop Smoking Service to increase their chances of success - last year, over half of our clients successfully quit by the end of their course."
