Illegal drug addict?
Closest I can find with some quick searching: 
Japan's censors hit drugs pretty hard. Even stories like Welcome to the NHK wrote his drug addiction out of the plot entirely for the anime, while plots like Akira meanwhile have drugs featured but aren't overtly about drugs as the plot itself.

Wait, this might be closer: 
Episodes 1 through 4 feature a story titled "No Longer Human":
Ningen Shikkaku (No Longer Human):
A high school student seeks solace in narcotics to escape the dispiritedness that has come over his life. As he goes through the different stages of his life, it culminates in the questioning of his existence in the world.
Checking into it now.
