Why do people think nicotine is more addictive than heroin?

I have tried both. Heroin once and cigarettes alot. Heroin is the best feeling ever that anyone can have. Cigarettes taste nasty and give you a tiny buzz that lasts for two seconds. When I smoke a cigarette I don't get withdrawal at all and never feel the need to smoke again. Heroin was hell withdrawal and I crave it everyday. People need to get their facts right.
