My personal take on it:

At least he's getting help, which a lot of addicts don't do.

Though this does solidify my view as him as Preacher, books and words are nothing compared to the personal journey, but he's back at it again, another book is coming, another 'bible'.

But also, did he pull some string to get that 'medicine?', I'm from a 'socialist healthcare' country and you get a referral to a PSYCHOLOGIST (his own profession) for this kinda thing, dope only when there is either a great will for it (but a long months-years observation period is entered then) or when it's Obvious a danger to not treat it with medicine (think straight jacket cases).

Anyway, hope he recovers and starts eating some veggies again, don't buy his books, they only cost money.
