No. We have to be careful when we make claims of reduced harm. We don't actually have that evidence. We have evidence of reduced exposure, which is not necessarily the same thing as reduced harm. Anybody making a claim could make the claim with a clear conscience that there is reduced exposure, but not harm, and I'm not aware of any data that has conclusively shown that heat-not-burn gives a much lower reduction in exposure. I'm not aware of any published results that show that to be the case. Definitely not enough time has passed to show that they're reduced harm products, and then there's questionable data about whether they actually provide reduced exposure.
