Andy Dick, the comedian, admitted to TMZ that he used crack cocaine after an apparent overdose on a Los Angeles street earlier this week, despite previously claiming only occasional use.Witnesses, including Shawn Harrell, found Dick unresponsive and "blue" near Hollywood's Highland and Yucca intersection, applying Narcan before he regained consciousness and appeared surprisingly calm.The Los Angeles Fire Department and LAPD responded to the medical emergency, but Dick was not hospitalized, and he later refused rehab, stating he was "100 percent fine" despite a history of legal issues.
