Re: MAPS: FW: NEJM article on "Ecstasy"
I am a retired physician. I'm not defending the report. No generalization
should ever be made for a correlation based on an N of 1, yet that is what the
authors do. Although the authors cite studies of MPTP toxicity, by their own
admission such studies show nigro-striatal damage on PET scan, which this
patient did not show. No chemical analysis of the drug he took was done, so
there is no evidence that the patient was ever exposed to MPTP. Absolutely no
conclusion can be reached as to the cause of his neurological disorder.
That is not to give MDMA a clean bill of health. It is to say that there is no
good evidence that the patient's disease was a result of taking MDMA or any
contaminant contained in the stuff he thought was MDMA. It's possible there
was MPTP present, but it is not proven. It is possible that MDMA itself caused
the problem, but that is not proven either.
I think your conspiracy theory however misses the mark. Drug companies are not
concerned about MDMA. Police are, parents are, religious groups are, the WOD
industry is. The beneficiaries of the WOD are not the pharmaceutical houses
(except as they are involved in making drug testing kits, or selling methadone
etc., or selling prescription narcotics, benzodiazepines, and stimulants that
will ultimately wind up on the street). The main beneficiaries of the current
drug laws are the legal and law enforcement professions (RICO enables the
police to fund their activities with money and the sale of property
confiscated from drug suspects), the drug rehabilitation industry, the private
prison industry, the various state prison employees, the construction firms
that make money when the states build more prisons, and certainly the drug
testing industry. It should not be forgotten that studies aimed against drugs
abuse will get funded. This will bias what gets reported in even the best of
peer reviewed journals.
