Matthew Perry's tragic death from a ketamine overdose has sparked conversations about the dangers of ketamine abuse and its potential for addiction. An addiction specialist highlighted that while ketamine can be beneficial for mental health, misuse can lead to severe consequences, as seen in Perry's case. His ex-girlfriend, Katyi Edwards, revealed that a breakup with Rachel Dunn, whom he considered the love of his life, may have triggered his return to substance abuse, stating that Perry was sober during their relationship. Edwards emphasized that Perry experienced deep regret over this breakup, which she believes contributed to his struggles with addiction. The Medical Board of California is currently investigating the doctors involved in Perry's treatment, which included ketamine prescriptions. This situation underscores the importance of understanding the risks associated with psychiatric medications when misused.
