Unfun fact: For tobacco production, specifically drying the leaves, are quite often used wood from local rainforest. Not very enviro friendly. The slovakian forest protection organisation VLK was working on some outreach materials about this topic but haven’t finished them, but I have read the draft.

Also, smokers not just die because of smoking. They die in bad health that often needs years of treatment, which can be very expensive, but also polluting and diverging resources from productive work… I am not sure about the pluses and minuses and final calculation, but it is definitely not super clear.

So no, smoking is definitely not a good way to protect environment.
