Question about drug counseling

MsJosie

My ex failed his court ordered drug test and was ordered 30 days to meet with a counselor. I just received notice from my lawyer that he met with a counselor and did some group and individual counseling and passed his last random drug test. I was just wondering if anyone knows how long drug counseling is? It can't be only 3 weeks long can it? Will I be able to request future drug tests prior to him visiting with LO? I can't see that he'll get off that easy can I? I just know that when he thinks he's in the clear that he will start using again. Does anyone know the process of drug counseling? TIA
