This is a free preview of a paid episode. To hear more, visit drmanaankarray.substack.com Health does not begin in hospitals. It begins in homes, schools, workplaces, neighbourhoods, and policy chambers. In this foundational chapter of Section 2, we explore the concept of health determinants - the broad constellation of factors that shape population health outcomes. Moving beyond individual risk f...

Not all poisons fit neatly into pharmaceutical or recreational categories. Some are industrial, environmental, botanical, or chemical - encountered rarely, yet capable of profound harm. In this final episode of Season 10, we explore miscellaneous poisons and unusual toxic agents that challenge forensic interpretation. We examine: * Carbon monoxide and other toxic gases. * Cyanide and cellular hypo...

Many substances designed to heal can harm when misused, miscalculated, or maliciously administered. In this episode, we examine medicinal poisons - therapeutic agents that may become toxic in overdose, error, or deliberate ingestion. These cases often involve complex pharmacology, variable tolerance, and subtle pathological findings. We explore: * Paracetamol toxicity and delayed hepatic failure....

Drugs sit at the intersection of medicine, behaviour, and law. Some are prescribed. Some are prohibited. All demand careful interpretation in forensic practice. In this episode, we explore the wide spectrum of licit and illicit drugs encountered in medico-legal investigation. The forensic practitioner must understand pharmacology, toxicity, behavioural effects, and post-mortem interpretation. We e...

Alcohol is among the most frequently encountered substances in forensic practice - yet its interpretation is rarely straightforward. In this episode, we examine the pharmacology, physiology, and medico-legal implications of ethanol in forensic contexts. From road traffic fatalities to custodial deaths and accidental injury, alcohol often plays a contributory role. We explore: * Absorption and meta...

Not all causes of death are visible to the eye. Some leave no bruise, no fracture, no tear - only biochemical disruption. In this episode, we explore the principles of forensic toxicology: the science of detecting and interpreting drugs, poisons, and chemical agents within the body. Toxicology often transforms uncertainty into clarity - but only when results are interpreted with precision. We exam...
