I tried vaping some liquid once and had to cough a lot. Dry herb vaporization has been the best type of inhalation for me so far.

Is there anything that cane be done about this or should I just back to combustion?

Vape the herb, and not carts?

Try running the vapour through a hot water bong.

I find rosin / dry vape that don't add anything are better than whatever garbage they are putting in the oils. The local shop should have answers.

Did you smoke pure or spliffs? Loads of people have trouble smoking/vaping straight herb after smoking mostly herb/tobacco mixes before. They aren’t used to the harsher weed smoke without the nicotine numbing their throat.

It may very well be the oil itself if your buying a generic THC cartridge who knows what they put in as filler. Stay away from the disposable carts and pens IMO.

If you are really interested in switching to vaping for health reason you should try a proper dry herb vape like dynavap which can do both straight herb and concentrate dab vaporization. Can't get smoother than a high quality concentrate vapor at lower temp pulled through some cold ice.

the voltage may be too low, i find 2.6-3.2v works on my uni pro plus. you might prefer live or cured resin too.
