We’d have to have more information. If a drug is “in your system” that’s not quite the same as being high on the drug.
Cocaine stays in your system like three days I believe. He could have done cocaine three days before no longer been high.
Marijuana stays in your system up to 90 days. He could have smoked a joint 3 months before the incident and still had marijuana “in his system”.
This is a tragic incident, I’m just pointing this out. I don’t know what state of mind the pilot was in but there is a big difference between having a drug in your system and being high on said drug.
We need to stop the war on drugs. Drugs are not bad.
