I smoked cigarettes for 47 years and have tried to quit smoking many times with many different quit smoking aids… I was diagnosed with COPD last year. The day after being diagnosed I began vaping. It was a easy transition for me. I began vaping with 24 mg. Nicotine strength and now vaping 3 mg. nicotine juice. I am now free from cigarettes for 1 year and 5 months. My lungs have improved greatly over the last 17 months and I no longer need my inhalers. I know that vaping has saved my life.
