Thank you all for the suggestions. I will try them all. Really need as close to analog taste I can get right now...preferably something that tastes like Winston, which I have smoked exclusively for the last 50-plus years! I still haven't given them up entirely but have cut way back from previous 2 pks a day to about half a pack, vaping as often as I can to make up the difference. I drive a taxi for a living and still feel like I should not vape in the presence of passengers, due to the newness of the experience...both to me and others less informed of the practice.
I think you are being most considerate of your passengers. That being said, I wonder if you can have the best of both worlds: vaping and consideration! My non-smoking friends love the smell of my eliquids, especially the RY4 blends that I have. The vanilla comes through and is a pleasant odor.
So, maybe you can ask your passengers if they mind if you vape and explain to them that they are not getting any second hand smoke. It will require a frequent explanation, but you might be surprised at how many people know about ecigs and even use them. In addition, you will be doing all vapers a favor by educating the masses. There is way too much negative press out there regarding vaping and we have to be advocates so we don't lose our right to vape!
If it is the difference between smoking and vaping for you, I would most definitely ask passengers if they would mind. Getting off the cigarettes is a life saver, my friend! Vape on!
