I stopped after 40 years by using a vape. I had a cervical cancer scare, and the surgeon said there was nicotine in my biopsy, and I should stop smoking
I used to smoke as many Marlboro as I could, but decided I had to stop at the age of 57, five years ago.
I only use classic tobacco liquid, and my ecig doesn't give off steam train style smoke like the ones young people have. I do vape all the time though and I'm still on the high strength, but it's a lot better than smoking.
Please give it a try and save your health. My poor friend with lung cancer is now housebound, she can't even go a few steps.
Also, the smell on someone that smokes is absolutely disgusting - think of putting out a bonfire with water, and that's the smell. There's also the fire risk, unless you only smoke outside.
Good luck. Vaping works for most people, you just have to decide you don't smoke cigarettes any more.
