Both compounds have the exact same chemical formula — C21H30O2; however, the atomic structure of each compound differs slightly due to the placement of atoms, and this small structural variation has a major impact on how each compound affects us.

Here at Canna City, we offer a wide variety of high-quality THC products that have been lab-tested.

CBD vs. THC side-by-side comparison

THC bonds extremely strongly to CB1 receptors located throughout the brain causing the psychoactive effects commonly referred to as the ‘high’ associated with Cannabis — altered perception, euphoric sensations and in extreme cases, feelings of paranoia or anxiety.

Conversely, CBD does not bond with CB1 receptors in the same manner as THC. Therefore, CBD is non-psychoactive.

Feature Cbd THC
Psychoactive? No Yes
Source Industrial hemp or medical Cannabis Primarily medical Cannabis
UK legal status With restrictions Class b controlled substance
Use For Wellness, sleep & anxiety relief Recreational use / licensed medicinal use
Risk of drug test Low risk – although trace levels of THC are present High risk
Must I have a prescription? No – supplements Yes – i.e. Sativex

The UK has strict guidelines regarding the use of cbd. Specifically, the UK will allow the sale and distribution of CBD as long as:

  • The CBD product was created using an EU-approved industrial hemp strain.
  • The final product contains less than 1 mg of THC per container (as of updated FSA guidance).
  • The CBD product is being sold as a food supplement and not as a medicinal product.
  • The CBD product has received approval for a novel food authorisation by the Food Standards Agency (FSA). (note: as of March 2021, all CBD products sold as food or food supplements must receive approval prior to being sold.)

On the other hand, THC is classified as a class b controlled substance according to the Misuse of Drugs Act 1971. If someone is caught possessing THC, they can face up to five years in jail.

There are limited exemptions for specific licensed medications such as Sativex (approved for treating multiple sclerosis-related spasm), and Epidyolex (approved for children suffering from severe epilepsy syndromes).

Why novel food authorisations matter

The Entourage Effect: will it affect your purchasing decision?

There are several CBD products available that claim to provide an “entourage Effect.”

Products claiming to provide an entourage effect typically include multiple cannabinoids — including low levels of THC — along with cbd, CBG, CBN and terpenes.

Proponents of the Entourage Effect believe that when used collectively, these cannabinoids produce enhanced therapeutic benefits.

In order to be considered compliant with UK regulations, full spectrum products must contain less than 0.2% THC.

While regular use of full-spectrum oils is unlikely to trigger a positive result on a drug test, frequent users may experience a very slight positive reading.

As such, individuals working in positions requiring safety critical certification would likely prefer to purchase either broad-spectrum (THC-free) or pure-CBD products.

Final thoughts

CBD and THC are chemically related yet are completely separated by laws and physiology in the UK.

Well-sourced and appropriately labeled CBD is a genuine and accessible Wellness product whereas well-sourced and appropriately labeled THC is tightly regulated outside of Prescription medication.
