Most confuse Propylene glycol with polyethylene glycol. You can say vaping has whatever chemical does NOT make it an e-juice for nicotine vaping. The second you say Vitamin E Acetate and THC IT IS NOT NICOTINE VAPING. The only 4  ingredients: propylene glycol or PG, Vegetable glycerin or VG, Nicotine could be based in VG or PG ranging in strengths most for consumers is 250 mg, lastly is flavorings most all are based in PG used at 1% to 30% in an E-liquid for vaping. In 100 mls of an e-liquid i mix 60 mls VG, 6 mls nicotine in pg, 5 to 15 mls of flavors in pg, and 8 mls to 29mls PG that is it. nothing extra no other chemicals added no wizardry no hocus pocus. ALL 100% FDA approved to be inhaled.
