I was vaping in the car and my husband who quit a yr ago and my son and his girlfriend who smoke analogs said that it smelled bad, like soured milk, I thought that this certain juice did smell a little funny but it taste great. So later that evening I was vaping it in the bedroom and went out to get a drink and when I came back I could smell soured milk too, so I don't vape it inside anymore. Then again I was at a concert outside Sat. nite and this girls says what are you smoking, I told her an e-cig and she said that it smelled just wonderful and did I mind if she stood behind me so she could smell it some more? So go figure each juice has it's own taste and it's own smell!
