title: Association of retrospective early smoking experiences with prospective sensitivity to nicotine via nasal spray in nonsmokers.
abstract: Greater sensitivity to early exposure to tobacco smoking may predict higher risk of becoming nicotine dependent. The most common measure of this sensitivity is the retrospective self-report Early Smoking Experiences (ESE) questionnaire. We examined the relationship between responses to the retrospective ESE and prospectively assessed sensitivity to nicotine via nasal spray in young adult nonsmokers (N = 58) with modest lifetime smoking experience (>0 but < or =10 lifetime uses). Nicotine spray (0 vs 10 microg/kg) was used due to ethical and practical concerns with administering tobacco smoke to nonsmokers. Responses to cigarette smoking on the retrospective ESE items of pleasant, unpleasant, nausea, relaxed, dizzy, and buzzed were compared with prospectively assessed nicotine spray effects (NSE) on the same responses. ESE responses were also compared with subjective spray ratings of nicotine reward (e.g., "liking") and perception (e.g., "feel the effects"), cardiovascular activity, and nicotine reinforcement via a nicotine spray choice procedure. Results showed that the retrospective ESE items of dizzy and buzzed were each associated with greater prospective NSE dizzy and buzzed responses to nasal spray nicotine. However, the other four ESE items were unrelated to the corresponding NSE items. Responses to some ESE items were also related to prospective nicotine spray reward and perception, but no ESE item was related to the cardiovascular or reinforcing effects of nicotine spray. These findings show that two of six retrospective ESE items, dizzy and buzzed, predicted the same prospectively assessed responses to acute nicotine via spray in young adult nonsmokers and may reflect a stable and reliable response to nicotine intake.
