LANSING, MI -- The Department of Licensing and Regulatory Affairs on Thursday released an official symbol that will be displayed on medical marijuana products.

It is an inverted green triangle with a marijuana plant in the middle, plus text that says "CONTAINS THC," short for tetrahydrocannabinol, the main psychoactive component of marijuana.

The symbol will go onto products sold under the Medical Marihuana Facilities Licensing Act approved by lawmakers in 2016. Under it, the state will soon license marijuana growers, processors, transporters, testers and provisioning centers -- the businesses that sell medical marijuana to customers. The state began accepting applications to license these businesses in December.

In addition to the symbol, marijuana being sold by or transferred to a provisioning center must be sealed and have a label containing:

- The name of the licensee and license number of the producer and/or the packager.

- The tag or source number as assigned by the statewide monitoring system.

- The unique identification number for the package or the harvest, if applicable.

- Date of harvest, name of strain, net weight, and concentration of THC or CBD.

- Activation time expressed in words or through a pictogram.

- Name of the safety compliance facility that performed any test, any associated test batch number, and any test analysis date.

- A warning that states the following: "For use by registered qualifying patients only. Keep out of reach of children. It is illegal to drive a motor vehicle while under the influence of marihuana."

As part of the new regulations, Michigan is implementing a "seed-to-sale" tracking system to track the medical marijuana in the new system.
