I'm posting this cause a friend of mine who has asthma and is allergic to Formaldehyd, described his experience as this to me:
Every time when he was vaping above 45-50Watts he had a sore throat the next morning had to use a special prescribed asthma spray because the symptoms went worse the next day for about a week.
The next week hhe just happened to vape on a prebuilt Lemo with 1,1Ohms at constantly 20-25 Watts and he noticed that he had absolutely no complaints so far and his asthma was completely gone.
