Should I be concerned about nicotine quality? I want to start getting into DIY and have no idea where to get my nicotine from. I can get low doses of naked 25MG nicotine in VG from a cignot brick and mortar store near my house but wanted to get a higher concentration. Making small batches with this low of a nicotine mg doesn't yeild anything worth using from a nicotine mg perspective. Anyway, can someone recommend a place to get some high quality nico?
