I've heard that before from others, but I'm not sure that prediction is what's actually happening. I was in a dispensary last week picking up clones, and that dispensary is going back to only selling to med patients. They said that the number of people applying for cards keeps growing every year, and they prefer that client base, so they are dropping rec sales.
I'm staying on the med side for a bunch of reasons. We do an outdoor in the summer... the difference between being able to have 8oz and 24oz on hand is huge when you do an outdoor. A summer harvest can carry us through the year, if want to go that route. Can't pull that off with rec numbers. Also, if you want to have a perpetual and/or sprout from seeds, the med system (up to 18 plants under 12") works better.
We're just legitimate OMMP -- one patient/one grower, very simple. For us, the flexibility is way more reasonable. It's definitely worth the price of admission.
