The main role of the “Office of National Drug Control” is to decrease the manufacturing and the usage of drugs.
<u>Explanation:
</u>
The war on drugs was initiated by Nixon when America was in a terrifying situation over the widespread drug use. Especially during the 1960's the 'counterculture' movement period, the drugs had become more popular in public. Then the Americans realized that the drug use was a serious threat to the country and it's moral. The ''Office of National Drug Control Policy'' (ONDCP) was started by former President Nixon who initiated the “war on drugs”. The “Office of National Drug Control” (ONDCP) took responsibility<em> to reduce the use, trafficking and manufacturing of illicit drugs and drug-related health issues, consequences, crimes and violence by building, executing and estimating U.S. 'drug control policies' on “war on drugs.”

That i don't know i guess they get more rights
Any answer choices? Based off my memory I'm going to say maybe <span>new treatments for patients suffering from tuberculosis and yellow fever</span>
