The deadline to enter the Driven to Quit Challenge is fast approaching. It's the Canadian Cancer Society contest that encourages smokers to quit the habit for at least the month of March. Senior Coordinator at Smokers Helpline, Naomi McNeill says participants can win a new vehicle or cash prizes up for grabs. Deadline to enter is February 28 and is made through the contests website or by calling the Canadian Cancer Society's smokers helpline.
