This is harmful misinformation that can literally lead to people dying from tobacco related disease.
Vaping, while definitely not healthy, is NOWHERE NEAR as unhealthy as smoking tobacco is. Especially when you do it as intended: temporarily for smoking cessation like I added decades to my life by doing.
I smoked for 18 years, the last 10 of which I tried every other smoking cessation method including prescription medicine and substance abuse therapy. They just didn't work for me.
Vaping did, though. In roughly 6 months I went from smoking a pack or two a day (depending on stress levels and alcohol intake) to neither smoking nor vaping at all and I haven't for over 3 years.
