whereas alcoholics can just see a doctor and detox at home
This statement is simply not true. There are many instances where alcoholics need to detox in a controlled medical environment ie; detox facility, hospital etc. I have a very good friend who just this past week had to go to a medical detox facility while coming off a two day bender.
I understand the OP's position, tho. It does seem a little bit out of balance in some situations comparing opiate addiction resources vs alcoholism treatment resources.
