hi my partner is on 180ml of methadone, he was originally scripted 320ml. But terrified due to drug testing starting in january, he has had to reduce quite quickly. Last week 8 were dismissed for just weed and speed. He is absolutley terrified, as we have 5 kids to support.He is not sure to go on subutex. is there any other option? He works in motor industry, will subutex show up in drug test?
