It's a ton of **** to be in someone's system. To play devil's advocate a little:
- THC: legal for medicinal purposes in Florida, stays in a person's system for a long time. Weeks. Quite possible it was not "active". Now, it could have been, sure, but it's just as likely it wasn't
- Xanax: as far as I know, this is an anxiety/depression medication. Not a reach that he takes this at least twice daily, as prescribed
- Vicodin and Dilaudid: pain meds and everyone knows this guy has been under the knife a ton, including multiple and well documented back surgeries
- Ambien: look back through the thread and you'll see how I feel about this drug, but if someone is on everything else above, it may be tough to sleep, and other golfers made comments before his fall from grace that he doesn't sleep
I'm only pointing out that he probably has a legitimate reason to be prescribed each and every one of these drugs. Now...no one, ever, should be taking them all at once.
