When can a controlled substance be shipped to another country?

The correct answer is that a controlled substance can be shipped to another country when an export license is obtained. The shipment of controlled substances across international borders is strictly regulated to prevent illegal drug trafficking and ensure compliance with international drug control treaties. An export license from the appropriate government authority, such as the Drug Enforcement Administration (DEA) in the United States, is necessary for legal exportation of controlled substances. This license ensures that all safety, legal, and regulatory standards are met before the substance can leave the country.

Obtaining an export license involves a detailed application process, verifying that the substance is legally permitted to be exported, and may require additional documentation or compliance with the importing country’s regulations. The importance of this process stems from the need to closely monitor and control the distribution of controlled substances to ensure they are used for legitimate medical or scientific purposes internationally.
