five0addict Reviewed by five0addict on . does using a keif catching grinder make the weed less potent; making you less high? self explanatory but if u wanna read.... ...i have a metal grinder that cuts instead of tares, it also has a keif catcher in the bottom, does having this take out a lot of thc and actually get you less high?
