STUDENT smokers could face the boot if they light up in college grounds.
Huddersfield New College, on New Hey Road at Salendine Nook, has ordered a complete ban on smoking on the site from next July.
Currently, there are designated areas for smokers outside the college buildings.
However, principal Philip Forrest said they would take a tough line with people who broke the new rule.
"In the first instance we will warn them about their conduct. Then we will follow the college's normal disciplinary procedure," he said.
Mr Forrest said the college felt a moral responsibility to stop people smoking.
He added: "Most of the students have been quite positive. The vast majority are non-smokers."
Mr Forrest denied the college's treatment of smokers was heavy- handed.
He said: "If people want to smoke during breaks and lunchtimes they can leave the site."
To help get people who are hooked on cigarettes to quit the habit the college has been working with the Stop Smoking Service and plans to do more.
They are offering seven-week sessions to help students kick the habit.
Smokers have also been offered lunchtime activities to take their minds off not smoking. These include a knitting club.
Mr Forrest said: "We are very keen to protect the rights of non-smokers and feel that we should be encouraging young people - and staff - to have healthier lifestyles."
