And being pharmaceutical grade alone doesn't mean it's suitable for inhale. It could be rated for topical or other applications.
"The only product that is guaranteed to be suitable for inhalation is a product that is (a) designated by the manufacturer as Pharmaceutical Grade, and that (b) also has a provable license for inclusion in a specific inhalable medicine. Needless to say this is virtually impossible to locate for the individual buyer."
I'm going to try this one:
Flavorless Hangsen e-cigarette e-liquid
Curious why they call it flavorless as oppose to unflavored. Nic has a flavor as does VG. Do they actually negate those flavors? I'm hoping it's just 'no flavors added'.
