He’s operated on hundreds of cig smokers but no stoners

The average stoner doesn’t smoke nearly as many joints as a cig smoker smokes cigarettes. Many cig smokers will smoke 10+ cigs a day but the average stoner doesn’t smoke that many joints

Joints don’t have as many carcinogens

It is generally harder to quit nicotine than weed

People can have medicinal cannabis but no one has medicinal cigarettes

@buticaaba you are absolutely correct! My dad hates vapes. He says the lungs of cig smokers look black and kind of like asphalt, and that the lungs of vape smokers retain their pink color but are covered in burn like blisters. He participated in a double lung transplant on a 20 year old vape smoker and has done multiple drainings of vape smoker lungs that filled with fluids because they’re absolutely full of blisters.
