What Is CBD (Cannabidiol)?

Cannabidiol, also known as CBD, is a cannabis compound found in hemp and sativa cannabis strains. Not to be confused with its psychoactive cousin component Tetrahydrocannabinol (THC), CBD offers significant medical benefits to users without any negative side effects. It’s important to note that though THC is responsible for the “high” feelings associated with ingestion of cannabis, CBD does not affect your body in this way. CBD-infused products will not get you high.

What is the endocannabinoid system?

Your body is home to the endocannabinoid system; a complex network of cannabinoid receptors and connected molecules. It’s responsible for helping regulate a huge variety of bodily functions, such as memory, sleep, motivation and reward, immune function, temperature, and appetite. The system contains two main types of receptor: CB1 and CB2. The differences between CBD (a non-psychoactive compound) and THC (a psychoactive compound) can be identified by studying the way each compound reacts with these receptors. CB1 receptors mainly influence the release and production of transmitters, while CB2 receptors are involved in maintaining the effectiveness of your immune system. THC interacts with these receptors by overwhelming the endocannabinoid system and bonding with the synapses, throwing it off balance and causing a psychoactive response linked with pleasure, memory, concentration and pain tolerance.

How does CBD interact with the endocannabinoid system?

Unlike THC, CBD does not bond with the CB1 receptors. Instead, it stimulates activity in both the CB1 and CB2 receptors without binding to them. Additionally, when CBD is introduced into the endocannabinoid system it increases the release of 2-AG. This is a naturally occuring endocannabinoid which is produced to enhance the overall effect of the endocannabinoid system on the body. In high concentrations, CBD can even activate the 5-HT14 serotonin receptor, which is responsible for producing anti-depressant effects. It also influences appetite, anxiety, sleep, pain perception, addiction mechanisms, and nausea.

Where does CBD come from?

Cannabidiol molecules are found in industrial hemp, as well as cannabis plants. Because industrial hemp has a low THC concentration, SmartCBD takes extra caution to preserve the raw nature of the hemp plant in order to extract from it the highest quality CBD. If you’re looking to purchase a CBD-infused product, SmartCBD’s extensive range offers a high-quality, natural alternative to wellbeing and health.

Frequently Asked Questions

Answered by SmartCBD experts

Is CBD legal in the UK?

CBD is legal in the UK and is commonly sold as a food supplement. All SmartCBD products are produced using hemp and are completely legal for consumption and sale in the UK.

Will I fail a drug test?

Drug tests are typically geared towards identifying THC and not CBD or other Cannabinoids. Some CBD oils may contain trace amounts of THC and this may register on a drug test. Take a look at our range of CBD oils’s and balms with zero THC.

Will CBD get me 'high'?

CBD oil will not get you ‘high’ in the traditional sense of smoking or ingesting marijuana. That is because marijuana contains high levels of Tetrahydrocannabinol (THC). THC is the drug that causes people to feel the “hazy” or “stoned” effects typically associated with marijuana use.

Is SmartCBD made synthetically?

No. All of our products are made 100% organically with natural and complex Cannibinoids, the way nature intended.

Does CBD oil help with pain?

Promising studies on the effects of CBD oil’s use for pain management have been carried out. CBD users say that Cannibinoids can offer a natural alternative for people who have chronic pain.

Will CBD make me drowsy?

A lot of our customers, when writing reviews about our CBD products, talk about how “relaxed” they feel as opposed to drowsy.
