Obviously, 4/20 is a very important day for pot smokers. And IF you decide to partake, you'll probably have to eat sooner or later. Iowa State University Police sent out a humorous reminder that they'll be waiting.

ISU Police posted this photo to Twitter Thursday morning with the caption "You've heard of speed traps? We have weed traps." And it didn't take long for the post to go viral. As of 5:00 p.m, the picture has more than 10,000 retweets and almost 25,000 likes.

Most found the tweet funny and a positive way for officers to ingratiate themselves with students, even joking that it was a "cop trap" and not a "weed trap":

Others viewed it as a hollow gesture:

Whether or not you agree that smoking marijuana should be considered a crime, I appreciate the police for trying to approach it in a less-threatening way. And I definitely prefer donuts, anyway. #GlazedNotBlazed
