Absolutely! You can find various brands that have this, though the one that comes to mind is Absolute Extracts. They sell an AC/DC cartridge that is made with very high quality materials. AE also uses a thicker blend of oil, meaning they use less thinning agents for the cartridge than more viscous oil blends. AKA a purer product.
You sure can! We actually are releasing our Single Origin Reserve ACDC next week! (shh)
