If you’re an experienced medical cannabis patient, you may have heard of the drug Delta-8 Tetrahydrocannabinol, also known as Delta-8 THC or D8. Delta-8 THC is closely related to Delta-9 THC - the form we commonly refer to simply as ‘THC’. Delta-8 occurs naturally in the cannabis plant in trace amounts but is often illegally produced semi-synthetically for the unregulated black market.

A brief overview of Delta-8 THC

Delta-8 was first described in 1941 by Roger Adams and associates from the University of Illinois1. It remained obscure until the passing of the USA’s 2018 Farm Bill with a loophole allowing for Delta-8 to be sold in the USA legally. It has since attracted worldwide interest making it important to understand what it is. In this article we aim to provide an overview of Delta-8 THC, its legality, risks, and similarity to Delta-9 THC.

What is Delta-8 THC?

Delta-8 THC is an isomer of Delta-9 THC, meaning it is a similar drug that contains the same number of the same atoms as Delta-9, arranged differently in its chemical structure. Different isomers or forms of the same drug may produce significantly different effects, and the health effects or safety profile of Delta-8 cannot be assumed due to its similarity to Delta-9.

Effects of Delta-8 THC

Delta-8 THC produces psychoactive (mind-altering) effects like THC at roughly half the potency per milligram, although little else is known. Delta-8 may also vary in terms of its onset and duration compared to Delta-9.

Is Delta-8 THC safe?

No. Delta-8 THC is currently unregulated in Australia, and black-market products containing it are untested and may contain harmful and unknown ingredients. Delta-8 THC itself has little research into its safety and unknown side-effects may occur alongside the side effects normally associated with Delta-9 THC, such as anxiety, nausea, mood, perceptual and behavioural changes.

Is Delta-8 THC legal in Australia?

No, Delta-8 THC is not legal in Australia. This is unlikely to change as it is chemically manufactured, and delta-8 THC products only have a brief history of human use, with little research on its effects and safety. However, Delta-8 THC may be naturally present (in trace amounts) in regular high-THC prescription cannabis.

Delta-8 alternatives

Due to Australia’s legal and regulated medical cannabis market, there is no need for patients to resort to unregulated and untested black-market products such as Delta-8. It is still important to remember that cannabinoids have many inherent risks that cannot be ignored, so if you have any questions about Delta-8 or the safety of cannabinoids, be sure to ask your prescriber.
