I bought some new e liquid at my local B&M, it tasted super awesome. I brought it home filled up my tank and noticed the ingredients said may contain trace amounts of Diacetyl and Acetyl Propionyl. I generally stay away from juice that uses diketones, but since I bought a 60ml I’m a little upset. Does anybody know what they mean when they use the terms may contain trace amounts? Are these amounts anything to worry about?
