Is vaping with 0mg nicotine safe while pregnant (to help ease the habit)? the ingredients are: water, propylene glycol, vegetable glycerin,& flavoring

Not recomended: inhaling aerosolized chemicals isnt best for you or for the baby. Vaping is a new product in the market and the effect on lungs/babies are still not fully understood. I would use this time to kick the habit to ensure that you give your baby the full potential to grow without interruptions by potential stressors like smoke

Recommend against : Vaping even 1 nicotine-free electronic cigarette (e-cigarette) “can produce transient changes in blood vessels similar to those seen in early atherosclerosis” REF: https://www.medscape.com/viewarticle/917031
