Here is another way i tried to catch some strong tobacco flavor with a eciggy.
On a classic ecig design i opened up the chamber at the draw end (look at the pictures). in this tiny compartment i put in a few " strands " of flavored tobacco and put the cap back. I could get some good amount of flavor.
The vapor passes over some tobacco and catches the tobacco flavor before it gets into your mouth. The flavor lasts for a some time, then needs to be replaced with a couple of fresh strands.
have fun.... cheers
