Long-term outcome of smoking cessation workshops.

Three hundred seventy-two (63%) of 590 enrollees in nine smoking cessation workshops held over a five-year period responded to a follow-up survey. Outcome data were collected retrospectively for six-month intervals from workshop to follow-up. Forty nine per cent of all enrollees graduated, and 56% of the respondents quit smoking during the program. Nonsmoking rates declined to an average of 25% by the first year post-workshop and remained relatively stable thereafter for periods up to five years.
