CENSORSHIP. 1947 - EPILEPSY STUDY.  HARRY ANSLINGER’S CONCERN   Today [for all practical purposes] it is against the law to do any medical research on Medical Cannabis in this country.   And has been so probably since the days of Harry Anslinger.   HOW? --- To quote another section of this book (on why Medical Cannabis will never be legalized) : 
. . . The narc's have a very long history of repressing / ignoring the truth. . . . There are numerous other ways the narc's have of assuring that Cannabis NEVER gets FDA approval. HOW? 
You want to do medical research ^[6] on Cannabis, you FIRST have to get a permit from the Drug Police. Of which, they simply don't give out.   In fact, since the passage of the control substances act (1970), all the way up until California passed Prop-215 legalizing Medical Cannabis under their state laws, NONE were issued. According to Chemical Heritage Magazine:
    "Today, American researchers who wish to obtain legal cannabis for scientific study must apply to the National Institute on Drug Abuse (NIDA), which maintains a government-funded, 1.5-acre marijuana farm in Oxford, Mississippi.   Compared with street marijuana, however, the government's plants are low in cannabinoid content, and some researchers have also complained of the institute's slow and seemingly arbitrary decisions.   In 1994 Donald Abrams, a professor of medicine at the University of California, San Francisco, proposed to study the effects of smoking cannabis on HIV-related weight loss, but his application was rejected by NIDA, even though it had been approved by the U.S. Food and Drug Administration.   When he then resubmitted his proposal, this time emphasizing the drug's potential negative effects, NIDA not only approved the study but also provided him with nearly a million dollars in funding.   Another researcher, Lyle Craker of the University of Massachusetts-Amherst, applied to the Drug Enforcement Administration in 2001 for the right to grow cannabis for research purposes as a way of sidestepping these potency and access issues.   For three years he heard nothing, until a federal court ordered the Drug Enforcement Administration to respond.   They said no, so he sued them. That case is still under way. " 
. . . . . The chill affected researchers as well as clinicians. Medical journals published dozens of studies before the tax act but few after its enactment.   As researcher Lester Grinspoon noted, " virtually no medical investigation of cannabis was conducted for many years " as a string of additional laws, including the 1951 Boggs Act and the 1970 Controlled Substances Act, further deterred research." --- T.
