the situation? meaning are they all alcoholics? i don't know, i hope not. 
i don't know most of the sikhs in the US. i do know that among white sikhs, probably 99% DO NOT touch alcohol or tobacco. converts tend to be more strict than those born into a faith (in my experience)
i know that among amritdhari sikhs, none drink, because if they do, they are no longer amritdhari (simple logic there).
among clean shaven (born in sikh families), probably most of them drink, just as most americans drink from time to time, but i don't know this for sure, because i don't pretend to know everyone.
among sikhs i personally know and spend time with, NONE of them drink.
but we don't have these statistics based on religion in the US, so it's really difficult to answer your question with any kind of authority.
