The Food and Drug Administration has issued a warning to a company that markets breathable caffeine.
AeroShot could face regulatory action over false and misleading labeling.
The company's website says the product gives you a higher level of freedom and control that you can only get from airborne energy.
Elsewhere it explains the powder in AeroShot reaches your mouth where it is swallowed and ingested.
The FDA says the labeling is misleading because the product cannot be intended for both inhalation and ingestion.
Officials are also concerned that consumers may try to inhale your product causing it to enter the lungs.
