My baby niece is moving in with me and he has asthma. We do not smoke cigarettes around him. Now, I vape medical marijuana. Is that ok?

Confusing post. The odor of cigarette smoke, which many smokers cannot detect, is on your clothes & hair. It is enough to double an infants risk of reparatory disease while smoking in front of it triples the risk. The data is well researched and reproduced in several studies. Vaping anything has not been around long enough to have good data but is likely less an issue than smoking.
