If nic is so easily destroyed by heat then what happns to it when it is vaporized? Many who " Sports Vape" using micro Ohm coils at11 to 15 watts or more get to much of a Nic buzz at even 6 mg per mg of nic.
Light and heat cause Nic to yellow and some say the taste changes a little but some like the taste better than perfectly clear nic.
If heat steeping destroyed the Nic then I would likely be suffering from severe Nic withdrawal. Iwas a tobacco users for over 50 years. Cigars, pipes , cigerates and chewing tobacco. Since starting vaping I have droped fom 18mg to 11 mg and have not touched tobacco in months .
When I post
I have speed steeped ejuice at 120 - 140F in both water and air in the plastic botles wich most equice comes in both premade and my DIY ones without any issues.
that means I hve in fact done so myself and have done so long enough ago to have real experience with the results.
