Despite the gravity of the two examples above, there is arguably a bigger scientific fraud that has existed far beyond 50 years. This fraud has to do with the prohibition of marijuana, a natural herb that has been used for over a millennium. This prohibition of marijuana has to be the greatest scientific injustice because no major scientific study gives considerable reason for marijuana prohibition. From the report by the Indian Hemp Drugs Commission in 1893 to the report by the US Drug Czar’s Institute of Medicine in 1999, there is a limited reason for prohibition.
