This thread ended in 2010 and I found it in the links below a recent thread. I just wanted to mention that this question has not been answered. 2 other comments:
Since that asking, there has been a concerted attempt, mainly by neurologists and MS drug companies, to discredit CCSVI treatment. The MS society has used donations by their supporters for some very questionable research, in an attempt to kill off real research into CCSVI. There has been at least one death which may be related to the blackballing of anyone and anything related to this treatment.
The benefits of cannabis are known. People have started hoarding cannabis in anticipation of its legalization, in spite of the fact that Sativex is already legal. I personally think Sativex use allows me to play piano better, and musicians have known this for more than a century. Anyone who has seen the film "
Reefer Madness" knows what that can lead to.

This seems to be a direct effect on my nervous system, which is compromised by MS.
I get the idea that it is far less important for MS to be treated than for the existing banking, drug, and medical establishments to continue with the status quo and existing revenue streams, regardless of whether any MS patients improve, stay the same, or die.
Against these enemies, CCSVI treatment hasn't got a prayer. Who was it said "You will know them by their fruit."?
