FAQ

 

Cannabidiol, or CBD, is a non-intoxicating component of the cannabis plant with enormous therapeutic potential. Researchers are currently studying the effects of CBD on a wide range of conditions including chronic pain, insomnia, PTSD, anxiety, epilepsy, dementia and more. Extensive preclinical research and some clinical studies have shown that CBD has strong anti-oxidant, anti-inflammatory, anticonvulsant, anti-depressant, anti-psychotic, anti-tumoral, and neuroprotective qualities.

Products infused with a crystalline CBD isolate, derived and extensively refined from industrial hemp, are available. But single-molecule CBD is thought to be less effective therapeutically than whole plant CBD-rich oil extract. The rich recipe of compounds in medicinal plants exerts healing effects through complementary action. This supports the idea of the ‘entourage effect’, where mixtures of cannabinoids, their co-occurring terpenes, and perhaps other molecules such as flavonoids and stilbenoids, have a greater positive effect than just CBD or THC alone.

Typically CBD is not associated with many side effects but these have all been reported:
– Dry mouth– Drowsiness
– Lightheadedness
– Rarely can cause feelings of mild intoxication

Cannabinoids (e.g., THC and CBD) are the chemical compounds secreted by cannabis flowers that can affect the human body. They work by imitating compounds our bodies naturally produce, called endocannabinoids, that affect nerve, brain and immune cell activity.Currently, there are two known primary cannabinoid receptors: CB1 and CB2 receptors. CB1 receptors are located in the central nervous system, and in some peripheral tissues. They affect appetite, muscle control, pain, cognition, thermoregulation, and our stress response. CB2 receptors are primarily found in immune cells, and at a lower density in the central nervous system. CB2 activation is associated with immune function and immune cell proliferation, inflammation, and pain. Although these two cannabinoid receptors have been studied relatively extensively, there are more cannabinoid receptors being examined.

The ‘endocannabinoid’ system is an integral part of our neuro-immuno-endocrine network. This is the system of organ and tissue signaling in the human body that sends and receives chemical messages and affects many aspects of human health including mood, pain, inflammation, stress response, and immune function.

Our bodies produce their own cannabinoids—endocannabinoids—primarily anandamide, and 2-AG (2-arachidonoylglycerol). A ‘phytocannabinoid’ or plant-derived cannabinoids like CBD or THC can activate the same receptors in the body and have similar or stronger effects than our endocannabinoids. This is similar to how morphine derived from the poppy plant can reduce pain by activating the body’s endorphin receptors.

We know the very specific receptors that THC activates in the body, primarily CB1 and CB2 receptors in the brain, but are still learning all the different rectors CBD interact with. One research article estimated CBD may interact with 65 different receptors in the human body, leading scientists refer to CBD as a ‘promiscuous’ compound.

At low doses of CBD, less than 150mg total per day, it is unlikely that significant drug-herb interactions will occur. However, it is always possible that drug-herb interactions can occur, and this is more likely the higher the dose. CBD and other plant cannabinoids can potentially interact with many pharmaceuticals by inhibiting the activity of cytochrome P450, a family of liver enzymes. If you are taking medication where maintaining a certain blood level is critical- such as anti-seizure, anti-viral, blood-thinning medications- talk with your health care provider or pharmacist before trying CBD.

Although both hemp and ‘marijuana’ are technically variants of the Cannabis sativa plant, there are significant differences between them. Hemp is considered ‘industrial’ under current regulations and is defined as having less than 0.3% THC.

In the US, the legal definition of ‘industrial hemp,’ (as defined in Section 7606 of the Agricultural Appropriations Act of 2014), is ‘the plant Cannabis sativa L. and any part of such plant, whether growing or not, with a delta-9 tetrahydrocannabinol concentration of not more than 0.3 percent on a dry weight basis.’

Marijuana generally refers to Cannabis sativa plants that have a high concentration of THC, and the word stems from the recreational use of THC rich cannabis for the purpose of getting ‘high.’ Hemp plants possess a high concentration of CBD, with only traces of THC, and hemp extracts are associated with medicinal use.

– CBD exhibits no effects on humans indicative of any abuse or dependence potential.

– To date, there is no evidence of recreational use of CBD or any public health-related problems associated with the use of pure CBD.

– Chronic use and high doses up to 1,500 mg/day of CBD are reportedly well tolerated in humans.

Cannabidiol (CBD) has many health benefits, without producing the psychoactive, ‘euphoric’ effects of THC. ‘Relaxing but not intoxicating’ is how some of my patients have described the effect. That said, I did have one patient that felt that a low dose of CBD did make her feel high. This is why we recommend starting with very low dosages.

Yes, as long as they are derived from hemp, not marijuana, and contain less than 0.3% THC. No medical marijuana card is required to buy or use hemp-derived CBD products.

Make sure the product you buy has been third party lab tested for the 3 P’sPotency (how much CBD is in it), Purity (any residual solvents from the extraction process) and Pesticides. Third-party lab testing should be available on the product website.

Unfortunately, CBD labels on products are often inaccurate and unreliable as far as their CBD content. A JAMA 2017 study found that nearly 70% of all products sold online made from cannabidiol—an extract of the marijuana plant also known as CBD—contained either higher or lower concentrations of the drug than indicated on the label.

CBD-rich products should be lab tested to verify they are free of pesticides, and other contaminants. Best to avoid products extracted with toxic solvents like BHO, propane, hexane or other hydrocarbons. Opt for products that utilize cleaner extraction methods such as supercritical CO2.

Beware of CBD vape pen oil that contains propylene glycol. When overheated, this chemical additive produces formaldehyde, a carcinogen, as a byproduct, according to a 2015 report in the New England Journal of Medicine.

Unlike THC, CBD has negligible effects on appetite and satiety.

An effective dosage can range from as little as a 5mg of CBD per day up to 150mg per day. Make sure to start low and go slow. Take a few small doses over the course of the day rather than one big dose. Use the same dose for several days. Observe the effects and if necessary adjust the amount. Don’t overdo it!

Most drug tests screen for the psychoactive compound THC, not cannabidiol (CBD). However, full-spectrum hemp extracts may contain trace amounts of THC, so it could cause a positive result when screening urine and blood specimens, especially when taken at high doses. I recommend a prudent and cautious approach to taking CBD rich hemp extracts in the context of urine drug screens.
