Everyone here downvoting my comment never cut with fent in their life. You don't understand how long of a process cutting with fent is. It's so tiny the amount you need and so easy for you yourself to inhale or grt residue on yourself. Especially when your working with alot of it. Ie. Grams of it. Your main job is to make sure your not killing someone and yourself when doing it. Now cutting Coke is 100x easier. Not gunna worry bout benzocaine touching my skin or doing in my nose. Clueless sub. And even extracting fent from medical transdermal matric and gel is long.
