It clears him overseas, but the FAA will probably take his tickets. They feel that if you show up for work, you intend to fly. There is no leeway in this. At a min he will have to do all of his certs over after treatment.
You're an idiot.
As far as the "spin dry" program goes...
This dude will take a 28 day "vacation", lose his medical for 6 mos while he does aftercare, maybe a Soberhouse, takes some phsych tests and does allot of "group hug" meetings.
He will be jerkin gear 6 mos from now with a shiny new Special Issuance Medical and monitored for 3 - 5 years, end of story (as long as he continues to comply with the aftercare).
This stuff is a smile and nod "check the appropriate box" bada bing program for first offenders thanks to the Americans with Disabilities Act.
