Hey hi, recently made juice with Borkum Riff pipe tobacco and mix of VG...Everyone says to avoid cigarette tobacco to extract, as it contains worlds every polluted chemicals, Am I good to go with pipe tobacco extract? Used just 4 salt spoon of Pipe Tobacco to make 10ml...Around 1.8g Tobacco I guess, The mix was 20% tobacco extract + 80% pure VG, Tastes awesome! Please lemmi know
