When an individual could swear that s/he saw or heard something but can't find reference to it, and worries that something like crack addiction might be the cause of the confusion.
Example of crack worry:
"Am I on crack, or did Rob Ford lie to the media?"

"How do you not know about that? Was there not a big media story about that, or am I just on crack?"

Example of inverted crack worry:

"Is that guy on crack or something? Why doesn't he remember our conversation?"
