Can a person who was a cocaine addict drink alcohol occasionally after rehab?

My husband is getting out of a 6 month drug rehab program on Friday. I want to know if it is ok to allow him to drink alcohol or not. Alcohol was never a problem foe him, cocaine was his only addiction. I do not drink very often. I will maybe have 1 or 2 drinks every couple of months. I just wanted to know if I should ban all alcohol from our home? I just need some guidance on this one. Serious, helpful answers please.
