The BluCigs commercial with Stephen Dorff (I think?) is what got me researching e-cigarettes.
I'm a member of another very active forum (gun forum) and I found a
thread on e-cigs there, that I probably would have overlooked if it weren't for that commercial. Granted, I skipped those type of e-cigs and went straight to a
mod after much research, but again, if not for that commercial, I'd still be smoking regular cigarettes.
