I've done that before using my old grinder.. that was about 2 years ago and then a short while after that it broke so i bought a coffee grinder but i call it a bud buster and i havent scraped the thing in about 18 months... and its pretty built up in there too... yesterday i bought like 5 vials of honey oil and ive been doing hotknives all morning.... anyways im just gonna go relax and enjoy my buzz
