CA already has its hands full (poorly) implementing it’s legal marijuana laws, it’s doubtful whether there is time, money or political willingness to go into retail stores and remove a product that’s federally legal to sell and own based on the Hemp Farm Act of 2014. It’s also poorly written (as referenced in the article). I agree with the poster that this has to be politically or financially driven.
Whether any of these CBD products will do anyone any good (or bad) is moot. “Cannabidiol is the hottest new medicine in mental health because the proper clinical trials do suggest it has clinical effects,” says Philip McGuire, professor of psychiatry and cognitive neuroscience at King’s College London. “It is the No 1 new treatment we’re interested in. But although there’s tons of stuff in the news about it, there’s still not that much evidence.” Large, long-term studies are needed; a 2017 review paper into the safety profile of CBD concluded that “important toxicological parameters are yet to be studied; for example, if CBD has an effect on hormones”.
CBD products have become increasingly popular in recent years, as more and more producers market CBD as the new "it" drug for the health and wellness set — one that has been touted as a pain reliever and a treatment for anxiety, among other potential applications. Last year, consumer sales of CBD products topped $350 million in the United states, more than triple the amount sold in 2014, and various estimates predict the market could reach $2 billion within the next two to four years.
Currently, the only official, FDA-approved use of CBD is as a component in a drug named Epidiolex, which will be used to treat severe forms of epilepsy in children and adults, and which will be, Carson hopes, available to patients by the end of the year. Carson says he developed an interest in CBD because parents of kids with epilepsy came to him having read about CBD’s potential benefits on the internet. “There’s lots of data now that I think really supports that CBD helps for epilepsy,” particularly in reducing the frequency of seizures, he says. Anecdotally, he noticed that the same parents reported another potential benefit associated with CBD: reduced anxiety. “I got the sense that some children did get benefits in terms of anxiety, and I think that’s where I wonder if for example CBD in coffee could potentially be helpful,” he says.
Cannabidiol has been found to act as an antagonist of GPR55, a G protein-coupled receptor and putative cannabinoid receptor that is expressed in the caudate nucleus and putamen in the brain.[34] It has also been found to act as an inverse agonist of GPR3, GPR6, and GPR12.[12] Although currently classified as orphan receptors, these receptors are most closely related phylogenetically to the cannabinoid receptors.[12] In addition to orphan receptors, CBD has been shown to act as a serotonin 5-HT1A receptor partial agonist,[35] and this action may be involved in its antidepressant,[36][37] anxiolytic,[37][38] and neuroprotective effects.[39][40] It is an allosteric modulator of the μ- and δ-opioid receptors as well.[41] The pharmacological effects of CBD have additionally been attributed to PPARγ agonism and intracellular calcium release.[8]

Now, while CBD derived from hemp or psychoactive cannabis (“marijuana”) is chemically identical, there may be reasons other than legal concerns to make the distinction. If the hemp in question is low in CBD as well as THC, it may take exponentially more hemp than marijuana to produce the same amount of CBD. So this raises concerns about concentrates of pesticides and other contaminants getting into CBD oil made from hemp — especially hemp that has traditionally been grown for industrial purposes, and under standards developed with that in mind. In the case of places like China, even those standards may be too lax or not enforced at all.
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.
