Synthetic cannabinoid containing products have become available in Australia since about 2010 with brand names such as Spice, Kronic, K2, Tai High and Zeus. Although these products are disingenuously labelled as “incense” or “aromatherapy” products, and “not for human consumption”, their branding and packaging indicates that they are intended for smoking or vaporising as unregulated cannabis substitutes. The consumption of these synthetic cannabis products has been linked to many hospitalisations and some deaths in both the USA and Australia.
Understanding the toxicity of synthetic cannabinoids poses a significant challenge given the rapid chemical evolution of this class of compounds over time (see Banister SD, Moir M, Stuart J, Kevin RC, Wood KE, Longworth M, Beinat C, Wilkinson SM, Glass M, Connor M, McGregor IS, Kassiou M (2015).

The project will focus on recently evolved SC compounds, particularly those detected in the last 2 years that have been strongly linked to adverse outcomes. We will synthesise these molecules and examine both their in vitro and vivo effects.
Specific aims of the current project may include:
1. If biological and toxic effects of SCs are exclusively mediated by cannabinoid (CB) receptors, or whether there are other actions that explain such effects 2. The structural components of SCs that confer CB receptor activity and/or toxicity 3. Whether SC effects in vivo are predicted by their in vitro cannabinoid 1 receptor (CB1R) affinity and efficacy 4. Whether SCs produce acute and long-term signs of toxicity in laboratory animals that are analogous to those currently being observed in humans
