Where can I buy a fake cigarette to quit smoking?

Hi! I’m trying to quit smoking, but I believe that my addiction is primarily behavior. I’m looking for a fake cigarette of some kind (Styrofoam, plastic, electronic) that is affordable (no e-cig) and I can buy in person or from a reputable online seller? I’ve found some cigarettes online, from places like Better quit and EZ quit, but the websites don’t look legit. Any ideas?

Thanks!
