I'll go a little deeper in the hope of providing a bit of additional clarity.
If we look at the definition of “tobacco product”, which is on page 2:
It includes papers, tubes and filters intended for use with [products that are made of tobacco and] a device, other than a water pipe, that is necessary for the use of that product and the parts that may be used with the device.
That device framing there, that is intended to capture the products that are used to heat tobacco. That puts those inside the definition of “tobacco product”.
Then if we go over to the definition of “vaping product”, and look down at the bottom, so now I'm no page 3:
It does not include devices and substances or mixtures of substances that are excluded by the regulations, tobacco products or their accessories.
So because those devices became tobacco products, they are not vaping products. This is an amendment, to put in this device thing, and it's purpose is to capture these heated tobacco products.
The last thing I would mention on that is this enables a bunch of regulatory authorities within the act. Those things can be fairly nuanced, and different products can be treated differently under those regulatory authorities if need be.
