Which act defines the legal structure for handling synthetic drugs in the country?

The Comprehensive Dangerous Drugs Act is the primary legislation that establishes the legal framework for the regulation and control of synthetic drugs within the country. This act outlines the schedules of various drugs, including synthetic substances, and sets forth the protocols for their classification, manufacture, distribution, and penalties associated with violations. It is designed to address the complexities posed by rapidly evolving synthetic drug variants by providing law enforcement and health officials with the tools to combat their prevalence and misuse.

The other options, while related to drug control, do not specifically encompass the regulatory structure needed for synthetic drugs as comprehensively as the Comprehensive Dangerous Drugs Act does. The Dangerous Substances Act may cover some aspects of drug control, but lacks the specific focus on synthetic drugs. The Drug Control Act generally oversees overall drug policies but may not provide the detailed stipulations regarding synthetic substances. Meanwhile, the Narcotics Lab Act is aimed more at regulating facilities that conduct testing and research on narcotics rather than directly addressing the legal intricacies involved with synthetic drugs.
