Cannabis beverages do not metabolize much different than edibles. Edibles can have a very strong effect, and so do beverages. The effects are normally much more intense than other cannabis consumption methods. When you drink marijuana, it goes first to the stomach where it mixes with the gastric acids. Because it is in liquid form, the onset of the effects is faster than with edibles. It goes from the stomach faster to the small intestines where THC gets absorbed. It gets then taken to the liver where it transforms into a more potent form of THC. When it is in the liver, THC gets transformed into 11-hydroxy-THC. 11-hydroxy-THC has a much stronger effect than Delta-9-THC.  Where it generally takes anything from 40 minutes to an hour or more to feel the effect with edibles, drinking cannabis has a much faster time. After as little as 30 minutes, the effects could possibly be felt already.
