my name is sean patterson. i am a resident of san francisco. i started as a smoker when i was probably almost 16. i'm now 41. the only reason i quit cigarettes after trying every other alternative was learning about vape products about three years ago. i haven't touched a cigarette in three years. you talk about harm reduction, and that's exactly what this is. i'm here for the same reasons -- same reasons as the people that are worried about our children, our youth. i'm on the same side as them. i believe we do need to have harm reduction, but they're looking at this in a wrong way with poor evidence and poor scientific study, so i want to share is a study done by truth.org which, of course, is pushing an agenda now that makes vape products look like they're pushing it directly to kids, which i don't think that's true and accurate, but this study is done called rethinking nicotine and its effects by raymond niyura, ph.d. director of science and training at the national institute for tobacco research and policy so it's at the truth initiative, t
