Build a quit-smoking and rehabilitation blog. This is a hot topic and can make it very popular and profitable.
Talk about quitting smoking and ways/obstacles. Quitting smoking can be a tough challenge – and your blog can provide support, motivation, and guidance.
Along with smoking cessation methods try to cover the health benefits of quitting, possible withdrawal symptoms, and messages/stories from former smokers. If you were on this path, share your personal journey and experiences.
You may want to write about vaping alternatives as well. There is great affiliate business scope there.
