Hallo Everybody out there!!

Is there someone here who is able to give me info how the treatment of alcoholics and drug addicts work in Japan? What is the general procedure in the treatment. And what the the general outlook on this by people in general. Is it more accepted for men to abuse alcohol and drugs than for women?

I would appreciate as much info as possible. I'm studying in Sweden to become an enrolled nurse. To compare the treatment and views between Sweden and another country is part of the course. Japan is such an interesting country but I have no knowledge in this matter.

I would be very grateful.
My best regards to you all
