This Edible Ain’t Shit 

“This edible ain’t shit,”

Refers to a joke format popular on Twitter in which a person says

meaning they don’t feel high after ingesting edible marijuana. The person then supplies a picture representing their level of intoxication after a certain period of time, when the edible begins to take effect.

Unlike marijuana taken through smoking, ingesting marijuana via food or drink such as a brownie, cookie, tea, etc. digests through the bloodstream, meaning its effects are less immediate, but last longer and can potentially be more potent than marijuana that’s smoked.

 “This edible ain’t shit”

would be said by a person refers to the feeling prior to feeling the effects of edible marijuana, and the picture used in the meme depicts their intense level of intoxication after the edible takes effect.
