Crack cocaine vs. opioids

All the discussion about opioids recently made me wonder, what happened to crack cocaine. There was a time when it seemed like three-quarters of the U.S. population was, or supposedly soon would be, on crack. Where did the discussion go? So I looked at Google Trends, and it indicates there is less attention paid now to crack. (Or maybe people are so familiar with it by now they don't have to Google it?)
