Hi everyone. As the title states, I'm looking for mangas which include:
a) a character addicted to hard drugs or even prescriptions drugs, anything is fine
b) a character suffering from social phobia

b)

Konbini-kun. -he's a NEET and hates going out.
Rules - well he has some problems admitting his sexuality....but I don't know if this really fits you request >.<

Thanks <3, I haven't read them yet!

Kiraboshi Dial - I just read this yesterday. One of the characters has claustrophobia, so although he will take long walks, he won't get in a car or bus, and is isolated from people.

Gorgeous Carat - Florian becomes forcibly addicted to opium, I think in vol. 2

You absolutely must read Rules, as recommended by zero-chan, though you may want to read Hydra first. MIYAMOTO-sensei's Angelic Conversation appears to be more specific to your request.

Thank you, scarletrhodelia! (:

b

Sagatte Omachi Kudasai really nice

and I second Angelic conversation it's beautiful

Oriolidae & Sparviero

Bukiyou na Silent?
The uke can't really express his emotions.
Hope this is what you are looking for >.<"

Well, the guy in Yubisaki no Koi suffers from chiraptophobia. (Morbid fear of being touched.)
