The extended count docs I have spoken to say they won't go higher than 24 because they can't be certain of personal use. I don't think there are many doctors willing to sign their name to higher plant count recommendations, because of the restrictions or requirements by those docs. I think patients who want extended counts are going to have to actually develop a relationship with the doctor, create a treatment plan, etc. I don't think it's as simple as writing a check where the amount depends on the plant count. The MMED has scared industry pot docs enough that they aren't risking their credentials for people who want to get high.
I think this is the grey area of the market that they are going to start cracking down on. If patients want extended plant counts, they will have to earn them by working with their doctor over a period of time, and I don't think that pot docs want relationships with medical marijuana patients, legit, grey, or other.
Citation needed, but I assume pot docs could be subpoenaed in a case involving a high plant count.
That being said, I will continue to get a high plant count, but more importantly for me, the increased possession. If I am hauling trim to make into coconut oil I'm not doing so two zones at a time, and rec rules have removed the weight 'problem' as far as I am concerned. It seems to me that having paperwork will demotivate leo if I am pulled over. I did my renewal in December at alameda/broadway. There was only one out of three docs that was doing extended recommendations.
I'm certain that YMMV.
edit- I think cannapages aggregates pot docs, if you have a free afternoon to call around.
