The innoken prism right now
I had only coughed with
vaping few times cause i had bought some ejuice that wasn't any known brand even tho it wasn't cheap but turned out was crappy...I remember it had a kinda wierd smell to it that I never smell again in a juice since then...it was kinda chemical smell like medicine or something hard to explain...
I don't know if your problem is the juice just saying ofc to have in mind...
Also I had coughed sometimes when I was
vaping kinda hard cause I was in a rush and stressed and my vape couldn't actually keep up the way I was inhaling...
And it's not I had spitback or anything but for some reason I was coughing...
Now I just vape more chilled when I vape mouth to lung and vape direct lung if I need more vapor...
Also I don't know how u store your juice cause heat and sunlight can make the nicotine go bad...
The fact that u change flavours a lot is something I do also but never had problems...
The only times I coughed was those and a little bit the first month of vaping cause of the transition from cigs or maybe cigs detox...
Could be also irritation in some flavour u vaped and needs time to go away??
I just say things but just Soo u have in mind to try after u try different pg and vg percentages cause only u can find out what really is causing the coughing to you...
Hope u figure it out soon
