I understand tobacco and chew and vapes aren’t good for you, because of all the other shit in there, but is nicotine itself as a chemical bad for you?

Nicotine affects your immune system (I only learned this recently because of my dad). He’s a long time smoker and now he has “all the cancers” (kidney, bladder, pancreatic, skin, colon), but not lung cancer. Seemed strange to be so I started reading. The short version is that nicotine fucks up your immune system so cancerous cells that are normally taken care of by your immune system aren’t taken care of. So smoking is basically inviting cancer to all parts of your body (not just your lungs).
