I bought a vype pen type e-cigarette for my husband, who has been smoking for at least 65 years. So far he has not smoked his real tobacco and is giving this new vype a try. He did find it a little strong, as I did not know which strength to get, and coughs when he takes in a deep breath. When I get more replacements, I will reduce the strength and see how it goes. He also said he might like a smaller version, so depending on how he gets on with this, I might also try the little cigarette style ones as a supplement. I would definitely recommend trying this product, as it really seems to work, without causing stress to the smoker, or others in the room!
