“Research shows that CBD content decreases when it is exposed to heat. It’s likely that the reduction in efficacy is due to the lower content. For instance, studies show that 71 degrees F can accelerate the degradation of CBD in a solution, resulting in less CBD. Potentially adding CBD to hot coffee may degrade it and reduce the amount of CBD available for absorption."


The 2014 Farm Bill[74], legalized the sale of "non-viable hemp material" grown within states participating in the Hemp Pilot Program[75]. This legislation defined hemp as cannabis containing less than 0.3% of THC delta-9, grown within the regulatory framework of the Hemp Pilot Program. This has led many to insist that CBD manufactured from hemp, is legal in all 50 states and exempts its oversight by the DEA as a controlled substance[76]. The 2018 Farm Bill is anticipated to provide further clarity regarding hemp regulations[77].


One of the strongest nutraceutical CBD oils is called Charlotte’s Web, with a 50mg dose. Charlotte’s Web is produced in Colorado by the Stanley Brothers, and named after Charlotte Figi, a girl who became famous in the US after her frequent seizures, brought on by the rare Dravet syndrome, were greatly reduced when she started taking CBD oil aged five. The company makes THC products too and is extremely successful, having just offered shares on the Canadian securities exchange, raising about $100m.
