The hearing began at 10:30 a.m. at Babylon Town Hall and is intended to gather input on legalization and how it has worked in other states.
Lawmakers expect legalization to be a big debate in next year's legislative session, which gets underway in January in Albany.
There's broad support among many lawmakers for legalization, but figuring out the details of the regulations and tax rules for the drug will be challenging.
This is fourth hearing on the topic held by the Assembly.
