7 things to know about Connecticut's medical marijuana program

Connecticut's Medical Marijuana Program is run by the Department of Consumer Protection. A Connecticut-licensed physician, APRN or physician assistant starts the process by certifying that a resident has one of the state's listed conditions, which number more than 40 for adults. The patient then finishes registration online through the DCP BizNet system by uploading proof of identity and Connecticut residency. Registration has been free since July 1, 2023. Adult-use cannabis is also legal, but registered patients pay no sales tax, get higher possession limits, and can buy medical-only product forms.
