in another recent thread, it was explained that dehydration is the main cause of a hangover from alcohol, but what makes you feel hungover from weed?

Maybe all those cannabinoids that are still sloshing around in there?

Cannabinoids are lipid soluble and are distributed rapidly throughout the body’s tissues, where they are released slowly and metabolized. The elimination half-life of THC is estimated at 20 hours to 10-13 days. Cannabinoids are metabolized in the liver to more than 20 metabolites, many of which are active.
