The lousy credit card aside, I liked this about the AMSA: "A growing contingent of medical students, who believe the medical profession needs more detachment from big pharmaceutical firms, has resulted in a 'modest rebellion' known as the PharmFree project, established by the AMSA in 2002.[2] Spending on marketing to physicians, which includes gifts to med students, rose from $12.1 billion in 1999 to $22 billion in 2003. Based on the premise that taking gifts from pharmaceutical companies creates a conflict of interest for doctors, the AMSA now urges both students and practicing physicians to 'just say no' to all personal gifts from drugmakers.
Other PharmFree activism has included a march on Pfizer offices in New York, where med students assembled at the firm's front doors and dumped thousands of pens marked with the company's logo on the doorstep. AMSA also started the Counterdetailing Campaign in 2005 to encourage physicians-in-training to educate practicing physicians about alternative sources of information regarding pharmaceuticals. Since "detailing" is the concept of drug representatives selling biased information to physicians, AMSA came up with the concept of "counterdetailing" as the opposite concept, to bring physicians evidence-based sources of information. Thousands of medical students have since participated in the Counterdetailing Campaign."
....and I didn't like this about the AMA: "The AMA also derives a significant portion of its income by selling physician prescribing data to pharmaceutical companies.[18] It continues to do this despite physician outcry, claiming approximately 33 million in revenue in 2005 from this practice. However, the AMA does allow physicians to "opt-out" of having their information shared through the Physician Data Restriction Program (PDRP)."
...which is probably why:"Physician membership in the group has decreased to ~33% of practicing physicians, "roughly 244,500 of the estimated 850,000 physicians practicing in the USA. Membership numbers would be even lower, critics point out, if only physicians paying full dues were counted."
(couldn't find a reference for this one). - overall, the wikipedia article, I think should be disputed for a lack of neutrality. but the above facts seem correct.
