I know both of them are really harmful to our lugs and brain. One side smoking make you feel tired after you take it which can cause less efficiency while working and also makes you cough after a long time if not quit. On the other hand, smokess tobacco can cause lung cancer, gum cancer but at least it won’t hamper your efficiency of working. This the infomation I have and I want to know more so need your help. Which one do you think is more dangerous and defective for health.
This is a really tough question, which do you prefer: tongue, cheek, mouth and/or esophageal cancer or lung cancer? Hmmm…sounds like you should just chew gum, buddy!!
Neither is a "good" idea and neither is a correct choice. Smokeless tobacco does hamper your work efficiency, you have to carry a cup around to spit in all the time. I just think you need to consult your doctor about help with tobacco use cessation. Your health is more important than a choice like this.
Consider quitting altogether-I guarantee you’ll feel better 
God bless!
