3) pp.6-7 and p.11 make it clear that virtually every single piece of equipment currently used by non-cigalikes is a tobacco product, with the sole exception (probably) of generic batteries. That means coils, cartos, MODs (APVs and mech), and on and on. Even a lousy drip tip will be considered a "tobacco product" that can only be sold to adults, much as cigarette papers are today. Mind you, the FDA could theoretically regulate a 18650 battery under the deeming rule, but as a practical matter it's not going to do that since that would likely interfere with other uses. But there are no other uses for Provaris or even a humble ego spinner. They are deemed tobacco products under the proposed rule, and therefore must pass all the tests described in item #1 above.
This can't happen unless the FDA's regulatory mandate is changed to include non-medical electrical/mechanical devices. If they try to do this, they'll get laughed out of the courtroom.
