I believe that strong cigarettes are still more harmful than light ones. There seems to be more chemistry in the lungs, though. After all, ordinary cigarettes can be made into lungs only with the help of chemistry. Therefore, I switched to stronger ones, although I smoked lungs for a long time. For one smoke break, I needed 2 weak cigarettes before, now one strong is enough. It's cheaper this way and I get less resin. So I leaned towards stronger ones.
All anti-tobacco resources always say that this is so. However, it is worth thinking a little and ..... this is completely wrong. Almost always on packs of tobacco (any) its strength (nicotine), tar content, CO is indicated. Naturally, Winston red (where everything seems to be in dozens, and nicotine is 0.8) will be more harmful than some vogue or kiss, where the content of all these delights is almost several times less. The fact is, any smoking is harmful, but the degree of harm is different everywhere.
