While 4:20 is for smoking and 7:10 is for dabbing, 9:25 is the time to eat cannabis edibles.
The basis of 9:25 is that responsible stoners work from 9-5, and cannot smoke pot at work. So you eat an edible for those who cannot... Or, maybe you eat it at work? Who am I to judge?
"It's 9:25, time for brownies!"
