Important Dates

1970: The Controlled Substances Act is passed, making cannabis use, possession and growth illegal nationwide.
2011: Governor Daniel Malloy decriminalizes marijuana in the State of Connecticut. While an offender would only face a fine of $150, as opposed to the potential for a lengthy jail sentence, this piece of legislation did not officially legalize cannabis in Connecticut.
2012: A medical marijuana program is signed into law.


Despite a kindred relationship with hemp growth and production (rope, sails, clothing, etc.) throughout the state’s history and especially during World War II, Connecticut has only recently passed legislation that allows for residents with qualifying medical conditions to possess and consume marijuana. Additionally, possession laws for those who are card-carrying residents are incredibly strict and require careful diligence and adherence.

Connecticut also makes a slight exception for those who are found to have a half ounce of marijuana or less on their person at any given time. While not completely decriminalized, these individuals are only fined up to $150 and generally don’t face jail time.
