Firstly, if you smoke weed... buy a 3-4 chamber grinder immediately. Secondly, once a month (or depending on how often you smoke) you should take the screen section of your grinder, put it in a sandwich bag along with rubbing alcohol. Zip the bag, shake it around, and wallah! Now you're collecting keif so fast you won't know what to do with it all. This public service announcement is brought to you by Makizushi, because I'm stoned off my ass from a bowl of keif. Happy tokin, brothers and sisters.
