OREGON:  A bill that would limit the size of medical marijuana growing operations in Oregon is generating angry opposition from some patients and activists.

The proposed measure, unveiled late Friday afternoon, is aimed at curbing the black market while prodding larger growers to supply the legal recreational market the state is developing.

This approach is winning wide support on the House-Senate committee charged with implementing the marijuana legalization initiative approved by Oregon voters in November. It also has varying degrees of support from many marijuana industry figures who want to develop a successful legal market in the state.
