Menthol Slows Sensitivity

Introduction

• Researchers At the Georgetown University Medical Center have found that deeper inhalation of menthol cigarettes increases the already substantial health harms from smoking. In combination with nicotine, menthol desensitises the type of nicotinic receptors found in lungs and airways that are responsible for nicotine's irritation, they found. "Menthol appears to slow or prevent the recovery of sensitivity after the first insult," says senior author Gerard Ahern.
