Marijuana-infused foods: how much is one serving?

On Saturday, the Seattle PI's Pot Blog published a story entitled, "The kinds of things you might eat from state pot stores".  It includes photos of candies, baked goods, and soft drinks that are infused with marijuana.  Below are a few examples.

Doses & serving sizes 
The labels on the cake pops indicate that they contain 111 milligrams of THC and 2-4 doses.  (THC is the mind-altering chemical in marijuana.)  The PI article explains the dosage information for edible medical marijuana products:


" . . . typically, a dose is equal to a high. So, a 2-4 dose edible should get a light-user of marijuana “high” four times (split the food into quarters). An experienced user with a built up tolerance might get high twice from it – eat half for one high and the other half for the second."

"Also, the rule of thumb is that no matter how much you start with (go slow), you need to wait for 90 minutes or (if you don’t feel anything in that time) longer to see what effects that portion will have on you."

For the emerging recreational marijuana market, the Liquor Control Board defines a single serving of a marijuana-infused product as equaling ten milligrams active THC, or Delta 9.  That means that one of the cake pops shown above, with 111 milligrams of THC, would contain about 11 servings if sold as recreational marijuana.
