I’m wondering if the Le Whif caffeine delivery device is really safe.

The claim is that particles in this inhaled product won’t enter the lungs, but is that true? I’d think particles would still make it down the airways, at least to some extent.

The manufacturer should post the particle size distribution of this stuff, and any other information they have pertaining to potential health issues. A caffeine jolt to the lungs, in the form of particles, does not sound like a good thing. I’d hold off on trying it before we see the relevant data and get some experts to weigh in.
