Organophosphates have been used for decades as pesticides, insecticides and herbicides, both in agricultural and industrial settings. However, their toxic effects on multiple body systems limit their safety. The clinical presentation of organophosphate toxicity varies depending on the route and duration of exposure. Although most research is focused on their cholinergic toxicity, emerging evidence points to their crucial contribution to metabolic dysfunction, including Type 2 diabetes and neuroinflammation. Beyond acetylcholinesterase inhibition, recent research highlights the potential role of organophosphates in disrupting endocannabinoid signalling, particularly by affecting endogenous ligands that modulate G protein-coupled receptors. This dysregulation may contribute to organophosphate-induced metabolic disturbances and inflammation. This review aims to explore how chronic subtoxic exposure to organophosphates contributes to metabolic syndrome and neuroinflammation through disruption of insulin and endocannabinoid signalling. It highlights the role of the endocannabinoid system in mediating these effects and evaluates its potential as a therapeutic target in organophosphate-induced toxicity.
