It does smell like your eliquid if you vape in the room for awhile. and it really depend on how you vape too, deeper and longer inhale would release less scent i guess
Have anyone try to mix this : 9parts Ecopure tabaco +3parts Marlboro + 1part Chocolate . My brother and I love it so much ,vaping all day. ( the combination may be different depending on how strong flavor of each of your eliquid flavors though, my Marlboro and Chocolate are super strong in flavor not nic)
