It's a tough thing to quit. Not like quitting sugar, but close. Nicotine is about as addictive as Cocaine, and WAY easier to get / more acceptable to use. I've known plenty of people who tried to quit smoking cigarettes, but only 3 actually succeeded. Most only quit when they take their last breath.

yeah, it's difficult when you have to live with an addiction....

Things like cigars, cigarettes, vapes, etc. contain a chemical called nicotine. Nicotine is addictive, and once you get started, it's hard to stop.

My dad used to smoke traditional cigars/cigarettes. Now he vapes. I haven't noticed much respiratory difficulty from him, but I was surprised when I learned that he started vaping, since he hadn't smoked in over a year when he started vaping.
