What does toxicology study?

The healing effects of drugs
The biochemical composition of drugs
The poisonous nature of drugs
The distribution of drugs in the body

The correct answer is: The poisonous nature of drugs

Toxicology is the scientific study of the harmful effects and the poisonous nature of various substances, particularly drugs and chemicals. This field focuses on understanding how these substances can adversely affect living organisms, including their mechanisms of action, symptoms of toxicity, and long-term effects on health. By examining the poisonous characteristics of these substances, toxicologists can assess risks, develop antidotes, and establish safety guidelines for exposure. The other options, while relevant to the broader topics surrounding drugs and their effects, do not accurately describe the primary focus of toxicology. The healing effects of drugs pertain more to pharmacology, while the biochemical composition of drugs relates to chemistry and drug formulation studies. The distribution of drugs in the body is a subject of pharmacokinetics. Therefore, the emphasis on the toxicological aspect underscores the importance of recognizing the potentially harmful consequences of drug exposure.
