The federal government has repeatedly and aggressively sought to discredit scientific research on the medical efficacy of marijuana ... then claims that there is a lack of evidence to justify safe medical use.
With it's monopoly on the legal supply of marijuana, the government can just say no for any reason. Researchers must apply for a federal grant from the National Institutes of Health (NIH) before they can study marijuana -- even if they do not request federal money.
When the government does permit research, it delays the process and forces scientists to change their study objectives, making them far less likely to find positive results.
This is where companies like EUChemicals come along to aid researchers and their projects with research chemicals, EUChemicals create synthetic cannabinoids and many other research drugs which means the researcher does’nt need any form of license to study the effects of THC.
