Health officials in several states are exploring a possible link between adolescent vaping and severe lung cancer.

Texas became the latest state to investigate, announcing its plans Monday.

Doctors are being asked to carefully document any lung cancer cases they believe may be linked to vaping, including obtaining a sample of the vaping liquid used by each patient.

The Centers for Disease Control reports 94 cases of lung cancer it believes are linked to vaping. The cases are spread across 14 states.

The Texas Department of State Health Services said additional information is needed to determine a cause. The agency is working with others across the country to investigate.

Vaping in teens and people in their 20s could impact brain development, Texas officials say.
