BOSTON U.S. Food and Drug Administration officials plan to investigate whether inhalable caffeine sold in lipstick-sized canisters is safe for consumers and if its manufacturer was right to brand it as a dietary supplement.

AeroShot went on the market late last month in Massachusetts and New York, and it is also available in France. Consumers put one end of the canister in their mouths and breathe in, releasing a fine powder that dissolves almost instantly.

Each gray-and-yellow plastic canister contains B vitamins, plus 100 milligrams of caffeine powder, about the equivalent of the caffeine in a large cup of coffee.

AeroShot inventor, Harvard biomedical engineering professor David Edwards, says the product is safe and doesn't contain taurine and other common additives used to enhance the caffeine effect in energy drinks.

AeroShot didn't require FDA review before hitting the U.S. market because it's sold as a dietary supplement. But New York Sen. Charles Schumer said he met with FDA Commissioner Dr. Margaret Hamburg and she agreed to review the safety and legality of AeroShot.

"I am worried about how a product like this impacts kids and teens, who are particularly vulnerable to overusing a product that allows one to take hit after hit after hit, in rapid succession," Schumer said.

Tom Hadfield, chief executive of Breathable Foods, which makes AeroShot in France, said in a statement that the company will cooperate fully with the FDA's review.

The company also said that AeroShot is not recommended for those under 18 and is not marketed to children.

Meanwhile, an FDA official who was at the meeting confirmed the decision, saying the review will include a study of the law to determine whether AeroShot qualifies as a dietary supplement. The product will also be tested to figure out whether it's safe for consumption, the official said.

The official spoke on the condition of anonymity because that official was not authorized to discuss the matter. Schumer pressed the FDA in December to review AeroShot, saying he fears it will be used as a club drug so that young people can keep going until they drop.
