Hey I’m in the same boat my son 42 he stayed clean for 10 days and I know this cos I was drug testing him every other day and then he went out stayed out all night I tested him next day and he was positive I was broken hearted I’ve told him to go as I have guardianship of my 13 year old grandson (his son) and I don’t want him to see this it is very normal for you to be suspicious and for you to worry this is what the drugs do to us mothers it’s heartbreaking please take care of yourself x
