any time you touch your buds you loose precious trichomes. when you grind it up some is collected on the teeth and other parts of the grinder and most fall into your kief catch.. this can all be collected and smoked. i cant stand it when people break good buds up with their hands. it breaks my heart even more when they will grab the biggest dankest nug in the bag and give it a few huge squeezes. dont squeeze your buds friends.
