If the person doesn't want to smoke, I don't think trying to change their mind is going to be a good solution or tactic. Replacing smoking is more than possible, and I personally switched to vape pens a long time ago, more about which here https://westcoastbud.io/products/vape-pens/. I'm more comfortable with this format, and it's cool that there are quality and diverse vapes available for purchase now.
