Daily Dose of BS March 8 cigarette advertising

I don’t remember cigarettes advertising on tv or on the radio, I was too young to have noticed.  I am old enough to remember seeing them on billboards, and I do remember when it was the Winston Cup and many of the cigarette slogans still pop into my head from time to time.  I am a non-smoker, it took a while but I quit that habit for the 39^th birthday about 10 ½ years ago.  I plan on being a non-smoker for the rest of my life.  I do wonder why when cigarette ads are banned on billboards and other media types why they are allowed on the lighted signs outside of convenience stores?  I usually don’t have any desire to smoke but seeing that pop up on the signs rotation while sitting at a stop light makes me think of stopping in and grabbing a pack, I won’t do it but I wonder why that is ok but running the commercials on tv, radio and billboards is not allowed?
