In what decade did the abuse of crack cocaine become widespread?

The abuse of crack cocaine became widespread during the 1980s. This decade marked a significant increase in the availability and use of crack, particularly in urban areas, where the drug was associated with a number of social issues, including violence and addiction. The introduction of crack cocaine, which is a freebase form of cocaine that can be smoked, made the drug more accessible and appealing, leading to a surge in its popularity.

This era also saw a corresponding governmental response, including tougher drug laws and a heightened focus on the so-called "War on Drugs." The 1980s were characterized by both media sensationalism surrounding crack use and significant societal impacts, further embedding crack cocaine in the cultural consciousness of the time.
