Yes, the capsules used in virto™ sticks are food-grade.
They are formulated using ingredients compliant with food-grade safety standards, intended for inhalation via heating, not combustion. These capsules—typically found in menthol and flavoured variants—are designed to release flavour when crushed and are manufactured following stringent internal quality and safety specifications set by BAT for aerosol delivery in heated tobacco products.
However, it’s important to note:
While food-grade ingredients are used, they are evaluated for inhalation safety, not ingestion.
