The Food and Drug Administration is issuing what amounts to a “hey, hey, not so fast, guys,” to the makers of a new inhalable caffeine product called AeroShot Pure Energy. They’ve been under the FDA’s eye for awhile, since Sen. Chuck Schumer brought up his concerns that the canisters could be used as a kind of party drug.

Reuters said the FDA warned AeroShot in a letter against false or misleading labeling, as well as contradictory statements about using the product with alcohol. They say the company labels the product as inhaled and ingestible, which is contradictory. The small canisters supposedly deliver a puff of caffeine combined with vitamin B into the mouth. Either you ingest it, or you inhale it, which is it?

“Caffeine is not normally inhaled into the lungs and the safety of doing so has not been well studied,” the FDA said in a news release. AeroShot says the particles are too big to enter the lungs, but the FDA says they haven’t proved that.

Their label also doesn’t have a contact phone number for reporting complaints, adds the FDA, and has conflicting statements about if its use for those under 18 is acceptable or safe.

“We plan to work closely with the FDA to meet their requests for information and labeling changes to ensure compliance with dietary supplement requirements,” Breathable Foods Chief Executive Tom Hadfield said in a statement. The company added that they do not promote it as a party drug or for use in those under 18.
