On their website, they have a super strength blueberry, but my concern is that in the description it says its a flavoring oil. Is it alright to use? Or does the product really contain oils. Now their natural blueberry sounds enticing, but in the description it says it contains Benzyl Alcohol. I dont even know if its safe for vaping. Ive tried research, checked the chemical's MSDS and still cannot find an answer.
