Final answer:
The controlled substance class level that does not have DEA dispensing limits is Class V. Class V substances have the lowest potential for abuse and are generally considered to have a low risk of dependence or harm. Cough suppressants with limited amounts of codeine or dihydrocodeine are examples of Class V substances.
Step-by-step explanation:
The controlled substance class level that does not have DEA dispensing limits is Class V.
There are five classes of controlled substances, with Class I being the most restrictive and Class V being the least restrictive. The DEA assigns DEA dispensing limits to controlled substances in Classes I to IV, which restrict the amount of the substance that can be prescribed or dispensed. However, Class V substances have the lowest potential for abuse and are generally considered to have a low risk of dependence or harm. As a result, they do not have DEA dispensing limits.
For example, cough suppressants with limited amounts of codeine or dihydrocodeine are classified as Class V substances. These medications can be purchased over the counter in some states and can be dispensed without strict restrictions.
