Connecticut took a different path than many other states. Instead of being voted on by a ballet, it was pushed by cannabis advocacy groups and eventually led to a bill on May 5 2012 by Connecticut’s state senate. The senate approved the medical marijuana bill and became law when signed by the Governor on June 1st 2012.
Connecticut has not legalized marijuana. Possession of small amounts of marijuana under 1/2 ounce were decriminalized in June 2011. You can still be fined up to $500 for possession of small amounts of marijuana. People under 21 would also face a 60 day suspension of their driving privileges. Possession of larger amounts of marijuana can lead to significant jail time and large fines.
i believe they had to write down a bill which made it legal. After that the bill has to get passed by the state and its governor people voted in its favor and thats how it got passed.
