And now, onto the thorny issue of legality. The simple answer to the question is yes — if it is extracted from hemp. The 2014 Farm Bill established guidelines for growing hemp in the U.S. legally. This so-called “industrial hemp” refers to both hemp and hemp products which come from cannabis plants with less than 0.3 percent THC and are grown by a state-licensed farmer.
The color of CBD oil drops can range from clear or slightly golden, to a dark brown almost black. Several factors determine the finished product color, including the type of CBD extract, the extraction method used, the carrier oil used, and additional ingredients. Full spectrum (whole plant) extracts tend to be darker in color, whereas isolates tend to be more transparent.
Studies have demonstrated that CBD has a low affinity for the CB1 receptors, but even at low concentrations, CBD decreases G-protein activity (3). CB1 receptors are expressed on many glutamatergic synapses that have been implicated in seizure threshold modulation. CBD may act at CB1 receptors to inhibit glutamate release (4). Studies have shown changes in the expression of CB1 receptors during epileptogenesis and after recurrent seizures (5). CB1 receptor expression is upregulated at GABAergic synapses and shown to be downregulated at glutamatergic synapses in epilepsy, contributing to lowering seizure thresholds.
In addition, big businesses work best when they can scale operations. With niche products like hemp-derived CBD oil, it is important to ensure products are third-party tested in order to verify their contents. Small businesses sell less products so can more easily perform these tests with care. Small businesses are also more nimble and can more quickly adapt to any new developments in testing, as well as adding new products to the shelves.
Extraction: The method by which CBD oil is processed from hemp plants can be very telling. Some manufacturers extract and process the oil using toxic materials like propane or butane; in most cases, these oils are cheaply priced. Safer extraction and processing agents include ethanol, which cleans the hemp plant of unwanted toxins; and supercritical carbon dioxide extraction, which strips harmful materials from the plant by changing the carbon dioxide’s temperature and pressure settings.
