HARTFORD — It will either be a slowdown or showdown this week when a key legislative committee takes a deep breath and votes on the new regulations implementing Connecticut’s medical marijuana program.

Both Gov. Dannel P. Malloy and Consumer Protection Commissioner William M. Rubenstein anticipate the eventual approval of the new rules by the 14-member Regulation Review Committee. Nonetheless, some members of the powerful committee are skeptical that the complicated rules safeguard enough against abuse.

If approved, the committee’s vote will be decisive and the state can prepare to start soliciting bids from would-be marijuana growers and dispensers.
