Ever wish you could mainline your coffee? Well, here's the next best thing: AeroShot, a new product that delivers "inhalable" caffeinated puffs, and has got productivity-obsessed technophiles buzzing.

AeroShot's delivery system is a light, plastic inhaler that shoots lime-flavored puffs of powdered caffeine to the tongue, where they are instantly absorbed. Each inhaler contains three puffs, providing a total of 100 mg of caffeine — about as much as in a large cup of coffee.

The product also contains 100% of the recommended daily allowance of niacin, vitamin B6 and vitamin B12. It's sweetened with stevia, an herbal sweetener that is up to 300 times sweeter than sugar and has no calories.
