Reduction Versus Abrupt Cessation in Smokers Who Want to Quit

Wednesday, March 31, 2010  
Lindson N, Aveyard P, Hughes JR. The Cochrane Database of Systematic Reviews 2010 Issue 3. This version first published online: March 17. 2010 (no citation available, but abstract available here)

This systematic review compared quit rates in reduction to quit and abrupt quitting interventions to see if reducing to quit is at least as successful as abrupt quitting. Randomized controlled trials that recruited adults who wanted to quit smoking were included in the review. Studies needed to include at least one condition that instructed participants to reduce smoking before quitting, and at least one arm that instructed participants to quit abruptly (i.e., set a quit date with no reduction beforehand). Pooled results found that neither reducing nor abrupt quitting produced significantly different quit rates. The authors conclude that more research is needed into which method of reducing smoking is the most effective, and which categories of smokers benefit most from each method.
