Summary of Key Findings

• Smoking abstinence at end of program:

• Among program completers: 41.3% (83/201)

• Having a lower CO level at program enrolment was a significant predictor of being more likely to quit
• Attending the TDC program for a longer duration was a significant predictor of being more likely to quit.
