started with e-cigs on thursday. 901 and 15 carts. Quickly realised this was going to work and ordered more kit yesterday. None arrived this morning, 4 carts left and all day tomorrow I am working where I cant smoke tobacco but e-cigs will be fine. The 4 carts will cover that, but this is the interesting part, I am now having to smoke tobacco as a substitute for e-cigs today. Been trying to find a local supplier since I got up. For somebody who never believed these would make an effectivve substitute to tobacco this is an amazing result.
