Backgrounder: Smoking Treatment for Ontario Patients (STOP) Study

Funded by the Ministry of Health Promotion, the Smoking Treatment for Ontario Patients (STOP) Study is exploring the most effective methods to help Ontarians quit smoking.

For information on how to participate, visit or call 1-800-350-5305.

Led by Dr. Peter Selby at the Centre for Addiction and Mental Health (CAMH), the study has reached more than 38,000 smokers in its first two years. That represents more than 20 per cent of the 175,000 Ontario smokers eligible to participate.

One out of every 13 participants in the study has remained smoke-free for 12 months – a result that indicates smokers who have access to effective counselling and nicotine replacement therapies are up to four times more likely to quit. Any smoking cessation intervention that can increase the quit rate above one in 50 is considered clinically significant.

The study has recruited participants a number of ways:

• Institutions such as CAMH, University of Ottawa Heart Institute and Thunder Bay Regional Health Sciences Centre have offered support to patients admitted for care;

• Twelve public health units supported members of their communities;

• Qualified smokers who called the 1-800 number received counselling and nicotine replacement therapies ;

• More than 100 community pharmacists recruited participants and provided counselling and nicotine replacement therapies;

• CAMH staff have traveled to 27 communities across the province where people have difficulty accessing smoking cessation services; and

• Twenty-one community health centres and Aboriginal health access centres are helping harder to reach populations.

Key Facts:

• Forty-three per cent of Ontario’s smokers make a serious attempt to quit smoking at least once over the course of a year.

• Almost 1.7 million Ontarians 18 years and older currently smoke.

• Of these, approximately 62 per cent intend to quit smoking in the next six months and 32 per cent intend to quit in the next 30 days.

• Ontario smokers make an average of 3.5 quit attempts before they quit for good.
