It's not clear to me. If it goes back 30 years, I would hope that these effects have already been discussed. I am open to another study because, in my opinion, the health effects have yet to be proven.
You drew a comparison to the tobacco industry. This comparison is quite strong and it really boggles the mind. However, in this case, the direct impact on health is not only physical, but psychological as well.
It's on this last aspect that the effects aren't clear. We need a better idea of what you are putting forward in your motion and what kind of studies need to be done. The difficulty is having other speakers and witnesses who can corroborate what is being advanced and determine the real effect. From my perspective, this is the difficulty in terms of studying this motion.
