I think this is the silliest thing. Adults who smoke weed regularly but don't own a grinder. If you're past being a teenager and like to smoke a lot of weed then you need to own a grinder. So much better than breaking up bud with your hands. I can't believe people even still do that. I also think it's crazy that people would buy blunts and smoke all the time rather than investing in a vaporizer and using that. That's just really crazy. Who else agrees that breaking up bud with your hands is a waste of time?
