Does anyone have a respiratory problem?

I have for years,
The other day I bought an ez vape vaporizer contraption.
I tried it, put some herb in it, heated up. Took a toke, nothing,no smoke. I bummed, what a rip, I was thinking.
checked out u tube, which explains. Its not like e cigs,
So I put the herb Mullein in it, (supposedly good for the lungs. I have never felt this good regarding breathing and lungs,
The herb mullein I've tried in tea, didn't much for me. Vaping is a hole new ball game.
The ez vape no thrills, cheapest cost $30.00, goes up from there. eBay.
Has anyone else tried this type of vaping?
