Absolutely yes. One of my favorite anime is GATE. It has a portal open from a alternate world at Roman level technology with legions and classical architecture, but it has dragons, elves, and magic and they send an army through to invade modern day Japan. The counter-attack is insane. Do a google search for “massacre of alnus hill”
tar, formaldehyde, and benzene are all added to cigarettes. Tar is a binder, the formaldehyde is a preservative, and benzene is an accelerant. The problem is that all of these things are toxic and/or cancerous.
Smoking loose leaf tobacco is the healthiest way to do it if that’s what you want to do. The little foam filters in cigarettes do nothing and the additives added to processed tobacco make it much more unhealthy.
