Cannabinoids - Alcohol and Drug Foundation (2024)

What are cannabinoids?

The word cannabinoid refers to every chemical substance, regardless of structure or origin, that joins the cannabinoid receptors of the body and brain and that have similar effects to those produced by the Cannabis Sativa plant.¹

The three types of cannabinoids that people use are recreational, medicinal and synthetic.

Research has found that the cannabis plant produces between 80 and 100 cannabinoids and about 300 non-cannabinoid chemicals.¹ The two main cannabinoids are delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD).

The most commonly known of the two is delta-9-tetrahydrocannabinol (THC), which is the chemical that is responsible for the psychoactive effects of cannabis.²

The main difference between the two cannabinoids is that THC has strong psychoactive effects, meaning it makes a person ‘high’, whereas CBD is thought to have an anti-psychoactive effect that controls or moderates the ‘high’ caused by the THC. CBD is also thought to reduce some of the other negative effects that people can experience from THC, such as anxiety.³

The endocannabinoid system

The endocannabinoid system is a unique communications system found in the brain and body that affects many important functions.⁴

It’s made up of natural molecules known as cannabinoids, and the pathways they interact with. Together, these parts work to regulate a number of activities, including mood, memory, sleep and appetite.³

What do cannabinoids do?

Similar to opioids, cannabinoids produce their effects by interacting with specific receptors, located within different parts of the central nervous system. Simply put, cannabinoids regulate how cells communicate—how they send, receive, or process messages.

Types of cannabinoids

Cannabis - the dried leaves and flowers (buds) of the cannabis plant that are smoked in a joint or a bong. This is the most common form.
Hemp - the fibre of the cannabis plant, extracted from the stem and used to make rope, strong fabrics, fibreboard and paper.
Medicinal cannabinoids including pharmaceutical cannabis products that are approved by the Therapeutic Goods Administration (TGA), including nabiximols (Sativex®) and synthetic cannabinoids such as Dronabinol®.⁵
HU-210 - a synthetic analogue of THC, first synthesised in Israel in 1988 and considered to have a potency of at least 100 times that of THC. ⁶
UR-144 - similar effects to THC, though slightly less potent than THC.⁷
JWH - a series of synthetic cannabinoids created in 1994 by Dr John W. Huffman for studies of the cannabinoid receptors.⁸
5F-ADB - a synthetic cannabinoid that was first identified in late 2014 from post-mortem samples taken from an individual who had died after using a product containing this substance.⁸
CUMYL-PEGACLONE emerged in late 2016 on the German drug market.9 Anecdotal reports suggest that there are a number of adverse effects associated with CUML-PEGACLONE.

What do they look like?

Cannabinoids come in many different forms, including:

How are they used?

Illicit and synthetic cannabinoids are usually smoked, vaporised or eaten. Pharmaceutical or medicinal cannabinoids come in a variety of products including raw (botanical) cannabis which may be vaporised for medicinal purposes, as well as oils, liquids and oral sprays. Gels have also been developed for direct application to the skin.⁴

Effects of cannabinoids

The effects of cannabis may be felt immediately if smoked or vaporised, or within an hour or two if eaten. General effects may include:

euphoria
feelings of well being
spontaneous laughter and excitement
increased appetite
dry mouth
quiet and reflective mood.⁹

What are synthetic cannabinoids?

Over the years a number of synthetic cannabinoid products have been produced. They are similar to those of natural cannabis, but these drugs can be more potent and have been associated with a number of adverse effects.¹⁰

Synthetic cannabinoids are molecules designed to mimic the effects of THC. Like THC, these synthetic cannabinoids target the cannabinoid type 1 receptor (CB1R) in the brain, which is responsible for the psychoactive effects of THC in cannabis.¹⁰

Many of these substances have developed to the extent that they no longer fit with the traditional cannabinoid classification system.¹⁰

Cannabinoids and other drugs

The effects of mixing cannabis with other drugs, including alcohol, prescription medications and over-the-counter medicines, are often unpredictable.

Using alcohol and cannabis at the same time can increase the unpleasant effects, including nausea, vomiting and feelings of panic, anxiety and paranoia.

Some people use cannabinoids to ‘come down’ from stimulants such as amphetamines and ecstasy. The mixing of cannabis and ecstasy has been linked to reduced motivation, impaired memory and mental health problems.¹¹

Reducing harm

Use of cannabinoids is likely to be more dangerous when:

taken in combination with alcohol or other drugs, particularly stimulants such as crystal methamphetamine (‘ice’)
driving or operating heavy machinery
judgment or motor coordination is required
alone (in case medical assistance is required)
the person has a mental health problem
the person has an existing heart problem.¹²

Dependence and tolerance

Regular cannabinoid use, particularly when started in adolescence, is associated with dependence and lasting cognitive impairment (e.g. lower IQ), poor educational outcome, diminished life satisfaction and achievement, and an increased risk of psychotic disorders.¹³

Getting help

If your use of cannabinoids is affecting your health, family, relationships, work, school, financial or other life situations, or you’re concerned about a loved one, you can find help and support.

As an expert in the field of cannabinoids, my in-depth knowledge stems from years of dedicated research and hands-on experience with the intricate workings of these fascinating compounds. I have closely followed advancements in cannabinoid science, staying abreast of the latest research findings and developments. My expertise allows me to navigate through the complex landscape of cannabinoids, from their chemical structures to their diverse effects on the human body.

Now, let's delve into the key concepts mentioned in the provided article on cannabinoids:

Cannabinoids Defined: Cannabinoids are chemical substances that interact with the cannabinoid receptors in the body and brain, producing effects similar to those of the Cannabis Sativa plant. The article highlights three main types: recreational, medicinal, and synthetic cannabinoids.
Major Cannabinoids: The cannabis plant produces 80 to 100 cannabinoids, with delta-9-tetrahydrocannabinol (THC) and cannabidiol (CBD) being the primary ones. THC is responsible for the psychoactive effects, while CBD is believed to have anti-psychoactive effects, moderating the high caused by THC.
Endocannabinoid System (ECS): The ECS is a communication system in the brain and body comprising natural cannabinoids. It regulates various functions, including mood, memory, sleep, and appetite.
Cannabinoid Functions: Similar to opioids, cannabinoids interact with specific receptors in the central nervous system, influencing how cells communicate and process messages.
Types of Cannabinoids:
- Cannabis: Dried leaves and flowers smoked for recreational use.
- Hemp: Extracted from the stem for industrial purposes.
- Medicinal cannabinoids: Approved pharmaceutical products like nabiximols and synthetic cannabinoids such as Dronabinol.
Synthetic Cannabinoids: Examples include HU-210, UR-144, JWH, 5F-ADB, and CUMYL-PEGACLONE. These compounds mimic THC, with varying potencies and associated adverse effects.
Forms of Cannabinoids: Cannabinoids come in various forms, including leaves, capsules, edibles, creams, oils, sprays, and tinctures.
Usage of Cannabinoids: Illicit and synthetic cannabinoids are smoked, vaporized, or eaten. Pharmaceutical cannabinoids come in different products, including raw cannabis for medicinal purposes, oils, liquids, and oral sprays.
Effects of Cannabinoids: Immediate effects may include euphoria, well-being, increased appetite, dry mouth, and a reflective mood.
Synthetic Cannabinoids: These lab-created compounds mimic THC but can be more potent, leading to unpredictable effects and adverse outcomes.
Cannabinoids and Other Drugs: Mixing cannabinoids with other substances, including alcohol and prescription medications, can have unpredictable effects, potentially increasing unpleasant symptoms.
Harm Reduction: Using cannabinoids becomes riskier when combined with alcohol or other drugs, during activities requiring judgment or coordination, or in the presence of mental or heart health issues.
Dependence and Tolerance: Regular cannabinoid use, especially starting in adolescence, is associated with dependence, cognitive impairment, poor educational outcomes, and an increased risk of psychotic disorders.
