BOSTON - The U.S. Food and Drug Administration said it plans to investigate the safety of inhalable caffeine that is being sold in lipstick-sized canisters, the Associated Press reports.

AeroShot launched last month in Massachusetts and New York, a canister that releases a fine powder that dissolves almost instantly in consumers?? mouths after inhaled.

Each portion contains B vitamins and 100 milligrams of caffeine powder, the caffeine equivalent of a large cup of coffee.

AeroShot inventor David Edwards, a Harvard biomedical engineering professor, said the product is safe and doesn??t include taurine and other additives contained in energy drinks.

The product didn??t require FDA review before reaching store shelves because it is being sold as a supplement. But Senator Charles Schumer (D-NY) met with FDA commissioner Dr. Margaret Hamburg and asked her 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.

The FDA told the Associated Press that its review would study whether AeroShot qualifies as a dietary supplement and whether it??s safe for consumption.

"We need to make sure that AeroShot does not become the next Four Loko by facilitating dangerous levels of drinking among teenagers and college students," Schumer said in a statement.

Breathable Foods, maker of AeroShot, said the product is not marketed to anyone under 18 and that it delivers caffeine safely into the mouth, just as coffee does. A single portion retails for roughly $2.99 at convenience stores.
