Regulating filter ventilation will change the relative reinforcing value of products resulting in nicotine/tobacco users facing the explore/exploit dilemma (ie, choice between unfamiliar and familiar options). This study examined the effects of price increases in higher-ventilated cigarettes (HVCs) and exposure to lower-ventilated cigarettes (LVCs) on explore/exploit patterns of tobacco-product purchasing in the Experimental Tobacco Marketplace (ETM).
HVC smokers (N = 20) completed one assessment session and 3 ETM sessions separated by weeks of at-home LVC exposure. In each ETM session, participants made 7-days of tobacco-product purchases as HVCs price increased across trials.
Prohibitive prices of HVC decreased the likelihood of HVCs purchases and increased the likelihood of LVC purchases. Initial exposure (week 1) to LVC reduced the number of cigarettes purchased when HVC prices were high and increased exploration of alternative tobacco products. Successive exposure to LVC (repeated access in weeks 2,5,6,9,10) decreased likelihood of HVCs and alternative product purchases and increased the likelihood of LVCs purchases.
Regulating filter ventilation may initially increase exploration of alternative tobacco products but lead to exploitation of LVCs over time. Tobacco control strategies should take advantage of this transition period when smokers seek information on unfamiliar products to implement harm reduction strategies.
调节滤嘴通风会改变产品的相对强化值，导致尼古丁/烟草使用者面临探索/开发困境（即，在不熟悉和熟悉的选择之间进行选择）。本研究考察了高通风卷烟（HVC）提价和接触低通风卷烟（LVC）对实验烟草市场（ETM）中烟草产品购买探索/开发模式的影响。
HVC 吸烟者（N=20）完成了一次评估会议和 3 次 ETM 会议，期间在家中接触 LVC 数周。在每个 ETM 会议中，参与者在 HVC 价格在试验中上涨的情况下进行了 7 天的烟草产品购买。
HVC 的禁售价格降低了 HVC 购买的可能性，增加了 LVC 购买的可能性。LVC 的初次接触（第 1 周）降低了 HVC 价格较高时购买的香烟数量，并增加了对替代烟草产品的探索。对 LVC 的连续接触（在第 2、5、6、9、10 周重复访问）降低了 HVC 和替代产品购买的可能性，并增加了 LVC 购买的可能性。
调节滤嘴通风可能会最初增加对替代烟草产品的探索，但随着时间的推移会导致对 LVC 的开发。烟草控制策略应利用吸烟者寻求有关不熟悉产品信息的这个过渡时期来实施减少伤害的策略。
