Thank you very much, Doctor. I just wanted to ask you a couple of questions.
We heard from other witnesses that there isn't sufficient—and I recognize that at the hospital you are at, you are doing some of this clinical research work yourself—evidence of the efficacy of e-cigarettes as a harm reduction technique. They say they think it is, but there isn't enough clear research. That's the first question. Do you believe there is clear research? Do you believe this constitutes clear research, or should there be more research done?
We've also heard that there is one major danger of e-cigarettes in the home. The liquid can be highly poisonous to children if it gets into their hands. That's the second question. What would you suggest—other than telling parents to take care, and we know how parents leave bleach and all kinds of things that are household hazards for their kids—to diffuse that poison risk or bring down the poison risk? What do you think of the research to ensure that this, in fact, is an efficacious form of either quitting or helping people to quit, or harm reduction?
