In theory, yes. But what I found was, as my nic levels dropped, the volume I was vaping increased. When I was at 2mg, I was going through upwards of 20ml a day!Started 18mg 1.8ohm now on 6mg @ 1ohm.
There is a bottle of unflavoured 18 mg floating about, which is used occasionally.
I dropped nic because of the TPD. In theory, bottle of nic will go 3 times further.
What really annoys me about vendors is the most expensive ingredient in eliquid is the nicotine.
The nic levels have dropped, but the prices remain the same.
