MUSLIM smokers in Huddersfield are being urged to celebrate a fasting festival by quitting the habit.
They are being encouraged to stop smoking when the month of Ramadan begins on Tuesday.
The call comes after research showed how a sizeable minority of people from ethnic minorities did not know about the health risks associated with smoking.
A survey said 22% of Bangladeshi men and a fifth of Pakistani men believed smoking had no effect on health.
The figures also showed how 90% of people in the UK's Asian communities had never heard about nicotine replacement therapy.
Lorraine Bradbury, manager of the NHS's stop smoking service in this area, said:
"Muslims, in particular, suffer from high rates of respiratory symptoms, heart disease, severe chest pain and long-standing illness caused by smoking."
Tobacco chewing is also high among Asian communities.
More than a quarter of Bangladeshi women and almost a fifth of Bangladeshi men regularly chew tobacco, increasing the chances of oral cancer.
A free helpline will offer smokers advice. The numbers are:
* Urdu: 0800 169 0 881
* Punjabi: 0800 169 0882
* Hindi: 0800 169 0 883
* Gujarati: 0800 169 0 884
* Bengali: 0800 169 0 885.
Lines are open from 1pm to 9pm on Tuesday.
