On one hand, I agree with the reading of the letter. On the other hand, it made him who he has become.
For this first album, it might be better not to, as it shows where he's coming from.
He has a vision for this album.
As for the weed, i'm a little aprehensive... While it realy can be helpfull, especialy with calming him and clearing his mind, it bothers me that the band is pushing him to use. I'm afraid they'll push him to use more, and stronger stuff.
A lot of great artists destroyed themselves by harddrugs...
Ryder has to much potential to go to waste.
