Technically, if his felony were reduced he'd be eligible for drug court. He could get it if:
1) the particular county has a misdemeanor
drug court (they don't all),
2) he has a documented history of drug abuse, as this is not a drug case ,
3) the DA is willing to take a chance on him, as they have complete discretion as to who gets it and who doesn't, and
4) and if there's a program willing to work with him, as frankly they are not fond of taking in people with theft
rather than drug histories. Even though we all know that theft offenses may very well be related to drugs, theft offenders are well known to cause in-house problems, and the programs won't all risk it.
In my experience, and I spent several years in treatment court as in-house counsel, he has about a 60% chance of getting treatment court. He'll likely need his lawyer to really push for it.
