My dad actually has been a long time smoker. His smoking he's coughing every night and in the morning. I really want him to quit or at least cut back by using an e-cig. He mentioned a guy at work got one, so I think I will buy him one. Now he smokes Kool Mild cigarettes. I don't know which e-cig would be the best for him. I was thinking an njoy NPro the smaller one. Not sure. Which e-cig would be best for him? Also which would be cheapest? I'm looking for something $50-65. So yeah I know it won't be the same as normal cigs, but I think it will be better than gum and patches. Thank you for your time.
