Compliance to FDA's elimination of free tobacco product sampling at vape shops.

Objective: The 2016 FDA's "Deeming Rule" prohibited free samples of vaping products. The purpose of this study was to investigate compliance with or adaptation to this newly established FDA policy.

Methods: Vape shops were recruited in Southern California between November 2017 and December 2018. Data collectors interviewed 121 vape shop employees who responded to questions pertaining to the sampling protocol at their shop. Nicotine levels used for sampling were also assessed for consideration of future policy adoption.

Results: Only 7.4% of shops were non-compliant to federal sampling rules. The remaining shops either: 1) charged a fee for samples (58.7%); 2) deducted the fee from the final purchase price (5.8%); or 3) eliminated product sampling (28.1%). Of the shops that charged for sampling (including membership fees), 94.4% initiated a minimal cost protocol (≤$1) for sampling. Half (50.0%) the shops that allowed sampling offered nicotine-containing samples.

Conclusion: There was high compliance (92.6%) to the change in policy among vape shops. However, minimal modification of sampling protocol was observed due in part to the lack of specificity on parameters of compliance, which lessened the potential impact of the policy. To further protect consumers, policymakers must develop unambiguous and comprehensive policies to achieve intended results and true compliance. At minimum, future tobacco product sampling policies should consider standardized pricing; alternatively, total elimination of tobacco product sampling is suggested.
