Final answer:
The Controlled Substances Act of 1970 declares marijuana a dangerous drug and makes its sale a prosecutable act. Despite some states legalizing marijuana, it is still considered illegal under federal law, causing conflict between state and federal regulations.
Step-by-step explanation:
Controlled Substances Act of 1970 and Marijuana
The Controlled Substances Act of 1970 is a law implemented in the United States. It classifies drugs into different schedules based on their potential for abuse and accepted medical use.
Under this act, marijuana is categorized as a Schedule I drug, which means it is considered to have a high potential for abuse and no accepted medical use. As a result, the sale of marijuana is prosecutable and regulated by federal law.
Although several states have legalized marijuana for recreational or medicinal use, federal law still considers it illegal. This creates a conflict between state and federal regulations on marijuana.
