Originally from Central Asia, cannabis is grown in many parts of the world today. The buds of the Cannabis sativa plant are covered in a sticky dusting of crystal resin, that contains therapeutic compounds known as cannabinoids.
There are far more cannabinoids than have been discovered. The Drug Enforcement Administration (DEA) has classified cannabinoids as a Schedule I controlled substance, the same as LSD and heroin. Owing to such regulatory barriers, the scientific inquiry and research of cannabis is difficult. However, earlier this year, the National Academy of Sciences released a new report that reviewed 10,000 scientific abstracts and reached almost 100 conclusions regarding the medical uses of marijuana and cannabis- derived products. The report suggests, "Political and non-political strategies to resolve regulatory barriers to cannabis research, an objective and evidence-based analysis of cannabis policy is necessary.”
