According to legal docs obtained by TMZ, the 'Real Housewives of Atlanta' star has to join a substance abuse testing program during his two years of supervised release once he finishes serving his 18-month prison sentence.

He’ll have to stick to the conditions of his supervised release ... and it looks like his probation officer will be keeping an eye on him and can search him if they have a reason to suspect something’s up.

That’s not all -- he’s also been ordered to lay off excessive alcohol drinking and can’t buy, use, or mess with any narcotics or similar drugs.

On top of his supervised release, Peter's also been hit with a $2.5 million restitution bill to pay the IRS.

Thomas' attorney, Melissa Owen, addressed Peter's post-release supervision conditions by referencing his January arrest for DUI.

Owen tells TMZ ... "Anytime there is an indication that alcohol has contributed to problems in this person's life, they will offer treatment or monitoring to make sure this person succeeds on probation."
