And the history of drug use has to be court records, Also they may require some level of testing for drugs ( if you ask for it)

When the child is born you NEED to go to court to establish him as the father. That way a court ordered DNA test will be done and you can be awarded with custody and get a support order. If you don't go to court then you will never get a support order and he will never owe any support. So, while in a perfect world you wouldn't need to involve the court this isn't perfect and you absolutely must get the court involved. If he wants visitation then he can petition the judge for it and get an order for visitation.
