When you buy marijuana or products that contain marijuana, the package has to include a label, and the information on the label is spelled out in state law. But unless you know what all those things mean, it might as well be written in Greek.
For smokeable pot, the label has to contain the producer’s business or trade name, and the producer's license number assigned by the state. "Producer" is another name for the grower, and that's important information. You want to know who is growing your bud, because you'll want to look for their product if it's good and avoid them if it's not.
The label also has to contain the concentration of THC and CBD, date of harvest, the name of the strain, and the net weight. This first two pieces of information are the most important for most people, because you need to know how potent the pot is, whether it is fresh, and if you're a pot connoisseur, you'll want to know the strain.
The activation time for smokeable pot is almost always going to be "immediate," but for edible products, it's a key piece of information.
The name of the lab that tested the pot is required, along with any associated test batch number and test analysis date.
The "Universal symbol" also has to be there, along with warnings that state "For use by adults 21 and older. Keep out of reach of children" and "It is illegal to drive a motor vehicle while under the influence of marijuana."
The name of the business that packaged or distributed the product has to be there, too, if they're different from the grower.
The "package unique identification number" refers to a unique identification number generated by the state’s seed-to-sale tracking system at the time the marijuana item was packaged, along with a harvest lot number.
