From what I've read, the bill in the CA state assembly does allow medical exceptions. I, however, would like to see marijuana regulated under a similar regime as alcohol. Commercial producers and retailers would have to be liscensed. This liscense should be difficult to obtain and easy to lose. Much like home-brewers and wine makers, there would be a legal limit on home production.

I can actually imagine a marijuana industry operating more like the wine industry with a huge number of "brands" available.

For medical needs, the separate caregiver system would remain in place.
