What is the maximum amount of substance containing opium that can be dispensed without a prescription?

The maximum amount of a substance containing opium that can be dispensed without a prescription is 8 ounces. This regulation is primarily in place to prevent misuse and abuse of opiate-containing products, which are classified as controlled substances due to their potential for addiction and dependence.

The law specifies that substances containing not more than 100 milligrams of opium per 100 milliliters (or per 100 grams) can be sold without a prescription, provided that the total quantity does not exceed 8 ounces. This amount allows for legitimate use in managing pain, cough, or diarrhea while maintaining control over distribution to help minimize the risks associated with opioid medications.

Understanding these limits is crucial for pharmacists in ensuring compliance with federal regulations and for protecting public health. The other amounts listed exceed the legal limit and would require a prescription, reflecting the increased risk of abuse and the need for medical oversight when higher quantities of opium are involved.
