Hello everyone, Just a little background about my problem. I have convinced my dad to try vaping as he has been smoking cigarettes for about 30 years or so and about 10 to 12 cigarettes a day. So i went looking for vape pens or devices and got so much confused it just overwhelmed me. If you guys can please point me in the right direction as how to get started, which device is best for a smoker like him? He wants a mouth to lung hit, so which will be best in this category? If you guys point me to a vaping device do tell me how much it will last and what special needs are to be taken care to get the best experience ( read about getting dry hit or burnt taste)? How much mg nicotine potency liquid should I buy( sorry if i am wrong with that slang)? I am also concerned as because if i choose something which gives him a bad start maybe he will not accept vaping. Please help me to choose best vape device so I can help him off the cigg.
