Final answer:
The contract for the purchase and sale of illicit drugs would be considered illegal and unenforceable because illicit drugs are involved.
Step-by-step explanation:
The contract for the purchase and sale of illicit drugs between Amara and Joseph would be considered illegal and therefore unenforceable because illicit drugs are involved. In general, contracts that involve illegal activities are invalid under the law. Therefore, the contract in question would not be legally binding or enforceable.
