Can I get my dad into rehab without his consent?

If you live in Fl you can - I am not sure about other states, you can see if they have similar laws to these Florida laws:

If you do live in Florida and use these laws, I would recommend having him go to http://www.synergygroupservices.com/

Both of my parents are alcholics, so you need to pay attention to what I'm going to say:

Rehab will not help your Dad, sure it may temporary stop him from the drugs but he will likely relapse the minute he is released. The problem with rehab is most of the time people with addictions are sent there because they are pressured into going by their loved ones, they are going because they want to appease others not because they want to get better for themselves.

Your Dad has a serious addiction and really the only way he'll stop is if he hits rock bottom, rock bottom can mean different things to different people. Rock bottom to some means hurting their loved ones emotionally, to others it may mean doing physical harm to themselves, to others it may mean physically harming or even ending someone's life, and in others its the addicts death that stops them.

As painful as this sounds you cannot save your Dad as much as you want to it's futile, because like I said before he doesn't want to get better, he wants to continue doing drugs, feeling his highs and feeling numb to the world. The best thing you can do is walk away because he's only going to drag you under with him, you need to forget about him and go out and lead your life, it may sound cruel and maybe to a point it is but what's the alternative sitting there holding his hand and pleading into his deaf ears to get treatment?

I will give you an an example- My grandfather on my Dad's side (he's 87) and he's been an alcholic all his life. Over the years he's gotten into many domestic assaults with his wife (mainly due to being intoxicated), he's had many drunken affairs, he's had car accidents while drunk and none of that deterred him. He's the type of drunk that starts drinking at 10am and goes hardcore until 9pm at night and he drinks whiskey straight up, no mixing it times that by 10-15 a day of those. Well this past summer he started having serious health problems, and was diagnosed with Liver Cirrosis and was told by the doctor another drink will kill you, well that was his rock bottom and he has not had a drop of alchol in nearly 4 months now.

You say you don't want to lose him? Well you already have, this addiction has pulled him completley under and he's not the man you grew up with, he's a shadow of his formerself. You need to tell your Dad' I will not sit around and watch this addiction suck you under nor will I watch you die! I have my own life, and my family who needs me, if you want to be in my life then you need to get off the drugs and find me, if not then this is goodbye".

No. He must either self-initiate rehab or have it ordered so by a court action unless he is put in your care.
