A ballot measure to legalize the recreational sale and use of marijuana in Florida failed to pass late Tuesday, sending shares of pot companies into freefall and dealing a blow to cannabis firms that had invested millions in the legalization campaign.

Florida voters will see recreational marijuana on the ballot in Florida as an initiated constitutional amendment , known as Amendment 3, on Tuesday, Nov. 5. Amendment 3 seeks to legalize recreational marijuana, allowing those 21 and older to have up to 3 ounces and up to 5 grams of cannabis concentrate.
