I work full time so I can't take him. He has a key worker who he talks to about his drug use. He's pretty candid with his keyworker, tells her about his usage and she stills fills his script for methadone. I think he needs a good spell in rehab and plenty of aftercare. Alex, I'm not trying to violate anyones liberties, I'm actually concerned about his health and the childrens well being. His blood pressure is thro the roof which I understand could go up even more when detoxing off heroin.Is there an outpatient program of any type there after detox or does he have someone to take him to meetings each day in the beginning?
Alex-- what about the child's rights? IMO, those trump the father's rights.

I stress, unless there exists clear and present danger, I think it would be a violation of human rights as well as detrimental to the children, to have them removed from their father's custody.

Right, that has been my thinking to be honest. Asked on here to make sure there's no other alternative. Frankly, I can't see one. His late partner's best friend (who suggested care) actually works for the civil service so I can ring her and let her know exactly what's been going on. This works because then he can't accuse me of betraying him (he can be quite a scary bloke) and the woman knows the system and will be able to improve the kids situation. So thanks for the replies, I'm going to do something (been praying on my mind for a while tbh).This is absolutely an unsafe, toxic environment for children!
The father has rights, yes, but that does NOT include having children and then putting them in danger. All children deserve a safe, secure and loving home - end of story.
Call CPS immediately. Whilst foster care isn't ideal in all cases, I feel that getting the correct agencies involved to assess the situation and likely intervene is the lesser of two evils here.
Once the children are removed from his care, he has the option to focus on himself, clean up his act and get his shit together. He can put in the leg work to get his children back, and get himself to a point where he can adequately care for these kids and provide them with what they need.
Kids in an environment with a father constantly doing H, methadone etc. whilst he is the only person responsible for them? That's utter bullshit. A toddler and a kid with special needs - what happens when something goes wrong and daddy is smacked out on the couch unable to help? Could be fatal.
Seriously, call CPS and let them deal with it - this is out of your hands. Don't turn a blind eye though..intervene, you could be saving these kids' lives.
Maybe I am being a bit naive but its a big step getting the social services involved. He does have redeeming qualities (believe it or not) as he'll spend nights in the hospital when the disabled kid is there. His late partner's family have got an idea what he's like but they don't want the kids (as one needs lots of care). Difficult situation and I'm not a parent myself but I hope I wouldn't behave like him even if I had lost my partner. But your right, I've been monitoring the situation and I'm worried so will do something. No choice tbh.. It seems I think you and your buddy there being very naive, and a bit ignorant. What about if this were your kid he was watching and while doing so he constantly high, he probably drives the kid around in the car high. You would actually let him watch your child like this? I somehow doubt it, but then again I dont know you so perhaps you wouldn't have a problem with that, but I think the majority of people would agree that this is clearly not a safe environment for this kid. I mean I certainly hope nothing happens\and I wish to be proven wrong as I don't want anything to happen, but it sounds like you would rather wait until something bad happens that could have clearly been avoided. Best of luck OP.

Now, here is the thing, in of it self, the fact someone is addict and/or the fact they are using a substance, does not, in of t self, constitute Actus reus to the offenses of Criminal negligence or fail to provide the necessities of life or anything similar. (at least not here) Ergo, if such was the case if I happened to be dispatched to that call...well, I may be tempted to charge the caller(because the caller wasted my time and attempted to use the justice system to carry out their personal morals), at the very minimum, I'd lol and get the fuck back in my crown vic.
