You’re welcome.

I quit after over 20 years. It was really, really hard. I still crave them. Won’t start again, just because quitting was so incredibly difficult. But, yeah. I, uh, think about it… Both sides of it.

Be aware, I cherry picked the information you had asked for from a much larger work. Just “Chapter 3 - The health effects of active smoking” has 37 sections. Everyone but the one I linked above has a list of negative effects. Have a look at the rest of it, too.

Don’t just confirm your biases. Look at the whole picture.

Wish you the best.

From their link:

Important note: smoking may offer a limited degree of protection in some individuals against the development of a small number of diseases, outlined below.

However, this information is of little relevance to public health, given that the amount of disease that tobacco may be said to prevent is insignificant in comparison with the far greater incidence of disease caused by smoking. Tobacco products kill one in two of their long-term users.

Why don’t you just get the health benefits in other ways that don’t include cancer?

Nicotine patches are better than cigarettes and vaping.
