Smoking is a known risk factor for developing various pain-related disorders. However, acute pain often triggers the craving for cigarette consumption, resulting in a positive feedback mechanism. In addition, there is evidence of decreased pain tolerance during the early stages of abstinence. Therefore, in this study, we aimed to investigate whether a period of decreased pain tolerance and increased pain intensity occurs during smoking cessation. A systematic literature search was conducted through PubMed and Web of Science databases for controlled studies investigating the influence of smoking cessation on acute (defined as pain presentation of < 3 months) and postoperative pain. The outcomes of interest included pain perception threshold, pain tolerance, pain intensity, and postoperative opioid requirements. The search strategy yielded 1478 studies, of which 13 clinical studies met our inclusion criteria. The included studies collectively represented data from 1721 participants from four countries. Of these, 43.3% of the included individuals were females. The mean age of the included subjects was 44.2 ± 8.2 years. The duration of smoking cessation varied considerably. The shortest duration was 2 h; others investigated the effect after more than 1 month of smoking cessation. Smokers had a history of 14.6 ± 9.9 years of nicotine abuse. The mean number of daily smoked cigarettes was 17.5 ± 10.3. Most studies examined in this systematic review show a negative influence of smoking cessation on acute pain. However, the affected pain modalities, the duration of the altered pain perception, and whether male and female smokers are equally affected could not be ascertained due to high heterogeneity and few available studies.
