Nope. I just would not put myself in that danger. It's the same as considering going into a pool of crocodiles and "hoping" you won't get eaten.
Also, if you go and join in the drinking fun at the stag party, what's going to stop you saying you may as well continue till after the actual wedding? And then some.
I personally wouldn't go. And if your friend is a real friend with your best interest at heart, he would understand completely.
