We've. In case you missed it, by merely inhaling from a tube, one supposedly gets the full-on taste of chocolate, as well as the sensory satisfaction that comes from eating it, sans the pesky calories. While I'm all for things from The Future, I'm not quite sure how I feel about this one.
Now Le Whif is back with a version that offers breathable coffee powder along with a jolt of caffeine (all in a new, biodegradable container). I'm really not sure if I want particles of caffeine going directly into my lungs, even though I am something of a coffee connoisseur (I live in Seattle, after all).
The product tagline says Le Whif of joe gives you the kick of coffee without the cup, which I guess could be true. But coffee isn't just about the brain-clearing buzz you get after downing the stuff. It's about the subtle flavors, starchy notes, and animated aroma. You don't, as far as I can tell, get those when you inhale the coffee directly into your lungs.
Also note that you're inhaling things into your lungs.
That said, I've e-mailed the company, and I will try this if they send me one. That way, you won't have to. Wish me luck.
