Move over, coffee and Red Bull. A Harvard professor thinks the next big thing will be people inhaling their caffeine from a lipstick-sized tube. Critics say the novel product, called "AeroShot," is not without its risks.

The product went on the market late last month in Massachusetts and New York, and is also available in France. A single unit costs $2.99 at convenience, mom-and-pop, liquor and online stores.

Biomedical engineering professor David Edwards said AeroShot is safe and does not contain common additives, like taurine, used to amplify the caffeine effect in common energy drinks. Each grey-and-yellow plastic canister contains 100 milligrams of caffeine powder, about the amount in a large cup of coffee, plus B vitamins.
