Health officials say their investigation into a recent outbreak of severe vaping-related illnesses is increasingly focused on products that contain THC.

The Centers for Disease Control and Prevention said Friday most people who got sick vaped THC, the ingredient that produces a high in marijuana.

A new study published by CDC found two-thirds who got sick in Illinois and Wisconsin said they vaped prefilled THC cartridges from one brand.

The investigation is ongoing. No single device, ingredient or additive has been identified.
