In reply to well, there are a few other studies:, posted by halcyondaze on November 8, 2006, at 19:12:49
While these studies do show that brain damage is correlated with drug users, they do not prove causation. It may be that these altered levels of chemicals are what led the people to use meth in the first place, and were unaltered by meth use. The urge to use meth may have been the body's way of compensating for the "damage."
The studies also don't show what the significance of this change is. There were no cognitive tests, for example. For all we know, it may be inconsequential.
