How can I have "quitting smoking" as my research topic?

what helps people quit? what kind of people quit (like how long have they been smoking or gender)? do patches and pills help? how is their health improved? do they start smoking again? how is their attitude after quitting?

lung cancer, a big one.
death rates.
hazardous ingridients in smokes.
what it can do to unborn babies.
how they have made it a law in australia to not smoke in certain places

How hard people who quit smoking thought it was, how addictive Nicotine is, how many times it takes to get addicted, steps you can take to quit, smoking rates in other countries... there's lots of things to research!
Good luck :)
