My everyday vape is a mix of menthol and watermelon. I have been using PA and also tried Loranns and one from madvapes, not sure who they use. Anyway, I have been wanting to try some other watermelon flavors to see if I can get exactly what I am looking for, not sure what that is though. There is a place, not an ecig vendor that sells something called "pure watermelon extract". Ingridents are Propylene glycol, alcohol, water and natural flavor. Just want to make sure it is safe to use, seems ok to me. Thanks
