Amendment 64 granted Colorado citizens the use and regulation of marijuana. Passed on November 6, 2012, it included a declaration industrial hemp should be regulated separately from marijuana and that the Colorado General Assembly is “to enact legislation governing the cultivation, processing, and sale of industrial hemp.” Soon after Amendment 64 went into effect, Colorado became the first state to contain certified hemp seed – designated as containing less than .3% THC – as well as free of weeds and disease.
If you go through Chapter 481 of the Health and Safety Code, you will find substances like THC (Tetrahydrocannabinol) and dronabinol (synthetic marijuana).

You also won’t find any of the other descriptors of cannabidol found on the Open Chemistry Database maintained by the National Center for Biotechnology Information or in any penalty group in Texas.
While everyone has their own unique body chemistry, it seems like the vast majority of people can ingest CBD oil without ever feeling any unpleasant side effects at all, and the remaining few will mostly likely experience only minor symptoms like stomach upset or dry mouth. Since scientists are using pure extracts from known sources, it’s likely that some consumer reports of headaches or other minor adverse reactions could be due to impurities in inferior CBD products.
