I wish my father would end up in jail.
That's disturbing. Why would you want him to be in jail?
He's doing drugs, I know it.
It's understandable you would want your father to be punished for drug use. Maybe he would be able to get clean if he were somewhere he could not get access to drugs.
I just want to get him in jail.
I would talk first with him to see if he can stop doing drugs but if he continues to do so, I think you have every right to report him to the authorities specially if the drugs he's using are illegal. I do feel sorry about you and him and I hope this gets sorted out instead of having to call the police.
