We have experience with the IV drug abuse with our one guy, alot will depend on what drug was abused. He was also positive at birth for several different things and was born at 35 weeks (not too premature, but a month) and went thru withdrawal.
As far as the measurements, i would not totally panic yet, I NEVER trust measurements they give me. Go there and do them yourself. We have gotten so many different measurements by whoever is doing it at the time, especially head.
If you want to email me or pm me about the IV drug stuff feel free to do so, I just dont want to write all about our guys history in a public forum.
