i think talking to your T is a good idea and I think what the other person said is true about being tested at birth. And even for pot, they will take away your son. At 7 months, i would try to stop, your hardest. easier said than done but it's not worth losing your baby in the long run. I would dare to say that you would think the same.

i know that feeling of feeling better when smoking. I am trying ot stop myself and it's not easy. i keep messing up. But they don't give a damn if you "mess up", they will take your son in a heartbeat if you test positive. Try your hardest to chill for a while. Keep thinking of being able to have that clean conscious. it's better for your son too. take care of yourself.
