Two promising techniques for smoking reduction, sensory deprivation and stimulus satiation, were applied in combination to five smokers. All were successful initially in achieving abstinence and four ultimately in maintaning abstinence. The issue of possible side-effects is worth considering. Quitting per se and both satiation and sensory deprivation may be stressful and as a result may potentially produce negative side effects. The observation of positive side-effects in these cases balances this possibility to some extent.
