Poopie, you are already mentally out... you know that WT rules, especially shunning is cruel and against human rights.
So why would you want to solve this problem the WT way?
If you told the elders, you would be supporting WT provisions. Wouldn't that be a little hypocritical.
OK, you don't like and you don't find it OK for this man to go to prostitutes and taking drugs.
So talk to him in private about it and tell him why you find he should change his behaviour. Show him some ideas how he can stop with the drugs, maybe special therapy.
But don't hound the elders on him.
And 60 cans of beer in one night. This guy had to pee a lot that night. Maybe he had a party with the 10 prostitutes (did you count them). According to my math skills everyone would have been drinking a little less than 6 beers, which would sound more realistic ;-)
