What is the maximum amount of opioid that can be sold over the counter?

The maximum amount of opioid that can be sold over the counter is determined by federal and state regulations to ensure safe access while preventing misuse. In the context of this question, the correct answer indicates that a maximum of 16.2 mg of opioid per fluid ounce is permissible for over-the-counter sales.

This regulation is in place to limit the amount of opioid available in easily accessible products, which is crucial in combating the opioid crisis and maintaining public health safety. Products containing lower quantities of opioids can be deemed safe for self-medication in certain circumstances, under the guidance of regulatory bodies that define these limits.

The other choices exceed this threshold, which could lead to higher risks of dependency or misuse. Keeping the maximum at 16.2 mg per fl oz represents a calibrated attempt to allow necessary pain relief while controlling the potential for abuse.
