(Noun). The mild depression following excessive use of marijuana, typically one to two days following the last time of use. The manner in which the afterblues hit will depend on how much marijuana was smoked and the quality; some afterblues will hit very hard but last less than an hour, and some will come on more slowly and last a day or more.
"The afterblues hit me like a Mack truck today at work."
