Strange your talking about 36mg, as I just started vaping it about a week ago. At first I was nervous that I may over indulge and get some adverse effects. Nothing, not even a hint of overdose.
I vape it straight and constantly, along with about 10-15 analogs a day.
This was my first time ordering 36, I got it on a great special-thought maybe it wasn't truly 36. I do notice a much better throat/lung/nose hit, but then to I started using manual batteries with my 510 about the same time.
On a side note, whenever I was on prescription drugs my doc always had to up my dose till I hit a plateau. Blood pressure meds, Xanax, Librium, always needed more than the "normal" or "average" person.
Some of us are just more/less sensitive to certain stimulus, imo.
Which makes me wonder about the others vaping 36 or higher and not feeling it.
Do you have a high tolerance for meds, street drugs, alcohol?
