A growing public health crisis is hitting eastern states and involves the often unintentional combined use of cocaine and fentanyl. The number of overdoses involving these two drugs together has skyrocketed in the last few years. Many users don’t realize cocaine has been contaminated with this potent opioid, and the result is too often a fatal or near-fatal reaction. Emergency treatment can save lives, but individuals also need to consider cocaine addiction treatment to stop drug use and eliminate the overdose risk entirely.
