The National Institute on Drug Abuse (NIDA) refuses to authorize American research into Marijuana as a cancer cure. Between that agency, the Drug Enforcement Administration (DEA) and others, they form a sinister merry-go-round of obfuscation and bureaucratic entanglements that means if they were to permit research, and it has been rare they have, they would do everything possible to prevent accuracy, unless, of course, they would be able to turn it into a negative against Cannabis. We have had to depend on other nations research. Fortunately, there has been a great deal of honest research into Cannabis. Now, Spain has discovered the curative powers of Cannabis/Hemp/Marijuana.
