PCP, thats about the only relavent thing here as i think thats what IMAs on with some of his posts
IMAs on the Angel Dust
SERIOUS! Read this, most the effects explain him perfectly
Phencyclidine (PCP) was developed in the 1950s as an intravenous anesthetic but, due to the side effects of
confusion and delirium (which explains why he thinks he can live map as good as a pro with no previous experience

) its development for human medical use was discontinued.
Detached, distant, and estranged from their surroundings (Hence why "its not his scene"
Numbness of the extremities and loss of coordination (Explains why hes shat himself over the power as its too much)
sense of strength and invulnerability (How he seems to drive and map at the same time, with only a rottweiler as help)
Users of PCP report difficulties with learning (Does he EVER listen to advice?

)
HERES THE BEST BIT!
In some users, PCP may cause acute anxiety and a feeling of impending doom; in others, paranoia and violent hostility, severe mood disorders, and in some, it may produce a psychoses indistinguishable from schizophrenia
