why the government of the day did not stop the drug use?

There could be various reasons why the government of the day did not effectively stop drug use. Some possible reasons include:

1. Lack of funding or resources dedicated to drug prevention and enforcement efforts.
2. Corruption or collusion within government agencies or law enforcement that allows drug trafficking to continue unchecked.
3. Lack of political will or prioritization of the issue by government officials.
4. Ineffective or inconsistent law enforcement strategies that fail to effectively address the root causes of drug use.
5. Social and economic factors, such as poverty, unemployment, and lack of access to education and treatment options, that contribute to drug use and make it difficult for the government to address the issue comprehensively.

It is important to consider these factors and work towards implementing evidence-based policies and strategies to combat drug use effectively.
