I chose that on purpose people lay people tend to significantly overestimate the health risks of smoking a cigarette.
Eating two pieces of bacon is actually less healthy for you than smoking a cigarette or two.
It takes about ten years of smoking 10 cigarettes a day to start to increase your risk of cancer or lung disease even a small amount.
The big problem is that smoking is extremely addictive - the rare person who can truly smoke only 5 cigarettes a day for years on end is extremely unlikely to suffer any adverse health effects from it.
Breathing wildfire smoke is thankfully not addictive that I’m aware of.
