CBD vs THC – Which is Better? Learning the Basic Differences

THC (Tetrahydrocannabinol) and CBD (Cannabidiol) are both extracts from the marijuana plant. However, there are many differences between them that are important to know.

The effect of THC and CBD depends on the amount consumed, but the most affected receptors are the parts of the brain relating to perception, motivation, memory, cognition and mood.

While both can affect the user through interaction with the brain receptors, the actions of both substances are extremely different. THC has very strong psychoactive properties which cause a high in those who take it.

Cannabidiol, on the other hand, is anti-psychoactive which makes it ideal for medical use.

How Do CBD and THC Affect Medical Conditions?

Both Cannabidiol and Tetrahydrocannabinol can be used to treat a range of medical conditions thanks to the effects on the body’s nervous system.

However, those reactions are very different, and therefore they have different medical uses.

Both CBD and Tetrahydrocannabinol have an effect on a number of medical conditions including:

Worry and Anxiety

While Tetrahydrocannabinol has been linked to feelings of paranoia, worry and anxiety, especially when taken in large doses, CBD, on the other hand, can counteract anxiety and is capable of alleviating social anxiety.


THC may exacerbate psychosis whereas CBD has antipsychotic properties that have led to it now being tested for use in treating patients with schizophrenia.


Those who need to achieve a higher quality of sleep should avoid Cannabidiol as it promotes wakefulness.

In these circumstances, Tetrahydrocannabinol is a better choice as one common side effect of taking it is drowsiness, meaning that it allows the user to enjoy improved sleep.

Cognitive Ability and Memory

Tetrahydrocannabinol is known to have a prolonged negative effect on the parts of the brain that are key for cognition, learning and memory.

Cannabidiol can protect the brain, even reducing impairments that have been caused by THC.

Why Is Hemp Oil More Popular For Use In Medical Treatments?

As Cannabidiol oil has none of the harmful effects on cognitive function that are associated with Tetrahydrocannabinol, it is more commonly used for medical applications.

Tetrahydrocannabinol is also categorised as an illegal drug which causes abnormalities in the heart and brain, whereas THC does not cause these issues.

THC is also known to be addictive, whereas Cannabidiol has no addictive properties and this too makes it more suitable for ongoing medical use.
