HELENA, Mont. (AP) — Montana health officials have announced two more cases of lung injury associated with vaping, and say they’re investigating other possible cases.

The Department of Public Health and Human Services said Monday a Cascade County teen was hospitalized this summer and again in October while a Lake County resident in their 30s was hospitalized this month. Both are recovering.
