He says, he has built up a tolerance to it so it takes more. He seems to minimize this! I am not stupid to drug abuse as I've had problems with my son through the years. From what I have learned. he will abuse his script the first 2 weeks, then borrows the last 2 from a relative. So, the last 2 weeks are pretty normal. He is prescribed 4 pr day. I wonder if he is snorting them. He seemed to be nasally irritated! Any information you can share will be greatly appreciated. I need to know what I'm facing!!!!
