Competing Interests
The authors have read the journal's policy and have the following conflict: DM works for the Oregon Tobacco Prevention and Education Program and is paid in part with Measure 44 tobacco tax revenues. If the federal tobacco tax disparity between pipe and RYO tobacco were closed, tobacco-tax funded state programs like TPEP would see an increase in funding. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
