NEVER smoke butter. Never ever ever. You may be thinking of a substance called 'budder' which is similar to, or the same thing as, 'earwax', depending upon who you ask- it's a resin extraction that has a gooey, sticky consistency but is very very pure and clean. It has nothing in it but pure psychoactive resins. No dairy.
