Matthew Perry Ketamine overdose

According to the toxicologist, he had “general anesthetic” levels of ketamine in his blood and that trace amounts were found in his stomach, however his last infusion was 1.5 weeks prior. So did he overdose on oral ketamine??? Also therapeutic levels of buprenorphine found. Curious to hear your thoughts. I personally view oral ketamine and buprenorphine a rather benign combination as far as accidental overdose risk goes. So tragic.
