I quit 20 years ago. My skin improved in moisture and appearance right away , my exercise endurance became better, my eating habits changed due to better taste perception, I had money in my pocket. I lost the guilt trip about influencing my children and folks around me. I no longer was polluting other folks airspace. I got a new career. I could write a book about how life has improved without being a slave to cigarette smoking and supporting an industry that profits through our my bad health and death. I no longer have to gear my life around where the cigarettes are, I don't have to smell horrid and have offensive breath. I don't have to spend any spare time smoking. I don't have to increase my risk of sudden cardiac death, heart -attack- stroke -cancer - emphysema-asthma-bronchitis- etc, etc. I have no regrets, just gratefulness to be blessed with the gift of not having to smoke and live chained to the rituals of smoking .
