Cannabis and Other Substance Misuse: Implications and Regulations

Area of Science:

• Forensic Toxicology
• Neuroscience
• Pharmacology

Background:

• Controlled substance abuse, including cannabis and illicit drugs, poses significant public health risks, often leading to severe intoxication and death.
• Postmortem analysis is essential for determining the cause of death in suspected drug-related fatalities.
• Understanding the neurotoxic effects and lethal dosages of abused substances is critical for public health interventions.

Purpose of the Study:

• To provide a comprehensive review of commonly abused controlled substances.
• To discuss postmortem analysis methodologies, lethal dosages, toxicity mechanisms, and regulatory frameworks.
• To highlight the neurotoxic effects of abused substances on the central nervous system (CNS).

Main Methods:

• Narrative review of scientific literature on controlled substance abuse.
• Analysis of characteristics, toxicity, and regulatory aspects of seven prevalent drug groups: cannabis, opioids, amphetamine-type stimulants, cocaine, new psychoactive substances, and hallucinogens.
• Examination of postmortem analysis techniques relevant to drug intoxication.

Main Results:

• Abuse of cannabis, opioids, stimulants, cocaine, NPS, and hallucinogens is linked to increased fatal overdose risk.
• Most abused substances exert neurotoxic effects, primarily targeting the CNS.
• Lethal dosage levels and specific toxicity mechanisms vary significantly across substance classes.

Conclusions:

• Strict regulation of controlled substances is crucial to mitigate harm and reduce mortality.
• Prescribers must adhere to guidelines to prevent diversion and misuse of prescribed medications.
• Enhanced understanding of drug abuse consequences can inform more effective prevention and intervention strategies.
