I have a friend who passed away recently and it's been over 4 months and they still can't find anything. He was very young and healthy, however there it a possibility that one of his friends slipped the drug Methadone into his food. Now this would have been the first time that we are aware of and it was 5-6 hours prior to him passing. As explained to us he woke up gasping for air and then fell to the floor. Everything has been ruled out and the last test to do is for drugs.

Please if you can give me any advice or suggestions I would greatly appreciate it.
