i used it back in the day when i was into sweet creamy/milkshake banana flavored juices and it was the only banana flavoring i liked. it was quite a yummy flavoring. lots of us have used it over the years even though it is one of them questionable flavoring. personally i vaped juices with it and other colored lorann flavorings in moderation and it didn't cause me any known issues but, back then i had an it can't be worse than the cigarettes i smoked for decades attitude and now i don't so i wouldn't use them today but, honestly am no doc or expert but, unless you have lung health issues, i don't see much harm in you vaping your 360ml worth of juice and than using only clear lorann flavorings to make more afterwards..
