Last Friday, the Chronicle did a feature article on proposed rule changes in Colorado's medical marijuana program. State bureacrats want to tighten the definition of caregiver and they want to reduce the number of patients a caregiver can provide for to five. That would wreak havoc with the state's burgeoning dispensary industry. That hearing is going on right now. I just listened in for a few minutes, and it sounds like a full house. This is a room that seats 500. The largest attendance at any previous Board of Health meeting has been about a dozen, so it seems like Colorado's medical marijuana constituency is out in force. The Board is expected to announce whether it will accept the restrictive rule changes at the end of the day. You can listen in, too, if you so desire. Dial 1-866-899-5399, then punch in the conference room number: *3529725* and you're listening. Don't forget to punch in the * before and after the conference room number.
