After Charlotte’s story got out, hundreds of families relocated to Colorado where they could procure CBD for their children, though not all experienced such life-changing results. Instead of moving, other families obtained CBD oil through the illegal distribution networks.
At age five, Charlotte suffered 300 grand mal seizures a week, and was constantly on the brink of a medical emergency. Through online research, Charlotte’s desperate parents heard of treating Dravet with CBD. It was controversial to pursue medical marijuana for such a young patient, but when they gave Charlotte oil extracted from high-CBD cannabis, her seizures stopped almost completely. In honor of her progress, high-CBD cannabis is sometimes known as Charlotte’s Web.
The ruling was contrary to existing evidence, which suggests the chemical is safe and could have multiple important uses as medicine. Many cannabis advocates consider it a miracle medicine, capable of relieving conditions as disparate as depression, arthritis and diabetes.
While parents treating their children with CBD had to proceed based on trial and error, like a folk medicine, they also had to wonder whether dispensary purchased CBD was professionally manufactured and contained what the package said it did. GW brought a scientific understanding and pharmaceutical grade manufacturing to this promising compound.
The first thing to know about CBD is that it is not psychoactive; it doesn’t get people high. The primary psychoactive ingredient in marijuana is tetrahydrocannabinol (THC). But THC is only one of the scores of chemicals – known as cannabinoids – produced by the cannabis plant.
So far, CBD is the most promising compound from both a marketing and a medical perspective. Many users believe it helps them relax, despite it not being psychoactive, and some believe regular doses help stave off Alzheimer’s and heart disease.
CBD first came to public attention in a 2013 CNN documentary called Weed. The piece, reported by Dr Sanjay Gupta, featured a little girl in Colorado named Charlotte, who had a rare life-threatening form of epilepsy called Dravet syndrome.
THC use may also result in unpleasant side effects such as increased heart rate, dry mouth, and memory loss.
Marijuana itself can have a number of short-term and long-term adverse effects, including impaired short-term memory, altered judgment, and impaired coordination. Research also suggests that marijuana can alter brain development and may lead to cognitive impairment.
CBD is often used to alleviate symptoms associated with:
CBD and THC have the same molecular structure, but there are differences in how these molecules are arranged that are responsible for the differing effects they have. By mimicking endocannabinoids, they bind with receptors and cause different effects in the body.

Non-psychoactive (does not produce a high)
The product you choose may depend on the effects you are trying to achieve. If you are trying to reduce stress or sleep better, for example, CBD may provide benefits without the negative side effects associated with THC. THC might be a better choice for symptoms or conditions for which the substance has demonstrated benefits, such as tremors or poor appetite.
Full-on stimulation of CB1 can deliver therapeutic benefits, but THC ’s psychoactivity intrinsically limits its medical utility, according to Big Pharma catechism. For the medical constabularies, getting high is by definition an adverse side effect. Allosteric modulation raises the prospect of increasing CB1 receptor activity without causing disconcerting dysphoria or needless euphoria.
Scientists at the University of Aberdeen in Scotland have synthesized a positive allosteric modulator of CB1 to treat pain and neurological disorders. When researchers at Virginia Commonwealth University tested the compound on mice, this experimental drug, known as “ ZCZ011 ,” had no psychoactive effects of its own, but reduced neuropathic and inflammatory pain by boosting the CB1 receptor’s response to anandamide, an endocannabinoid compound.
Every cell membrane has lots of receptors for many types of messenger molecules, which influence the activity of the cell. It’s not uncommon for a receptor to have two distinct binding sites or loci that can be activated by various drugs and endogenous compounds. The orthosteric site is the switch that a drug turns on, whereas an allosteric modulator can either amplify or decrease a receptor’s ability to transmit a signal depending on how the allosteric modulator changes the conformation of the receptor.
Healing Without the High?
When cannabidiol, an allosteric modulator of CB1 , docks at the receptor, it does not initiate a signaling cascade. But it does impact how the CB1 receptor responds to stimulation by THC and the endogenous cannabinoids. Allosteric modulation of CB1 changes the conformation (shape) of the receptor, and this can have a dramatic impact on the efficiency of cell signaling.
CB1 ’s orthosteric binding site is also the “keyhole” for THC ’s endogenous cousins, anandamide (the first endocannabinoid compound discovered in the mammalian brain) and 2AG (our most abundant endocannabinoid). Likened to the brain’s own marijuana, these endogenous cannabinoid compounds fit into the same orthosteric binding pocket as THC and activate some of the same signaling mechanisms.
Since the CB1 receptor was discovered in 1988, it’s been an article of faith among cannabinoid researchers that CBD , unlike THC , has little binding affinity for CB1 . But this notion is based on old science.
THC and CBD work in tandem; they are the power couple of cannabis therapeutics. Given the intimate synergies between these two plant compounds, how much sense does it make to attribute psychoactivity exclusively to one ( THC ) and not the other ( CBD )? Is it really accurate to say that CBD is a “non-psychoactive” substance?
