Final answer:
Purchasing alcohol for someone under the age of 21 can result in legal consequences, such as fines and jail time.
Step-by-step explanation:
Purchasing alcohol for someone under the age of 21 can have legal consequences, including fines and jail time. According to the National Minimum Drinking Age Act of 1984, states are required to raise their drinking age to 21 or face a reduction in federal highway funds. Although there may be some variation in the interpretation and enforcement of minimum drinking age laws from state to state, it is generally illegal to purchase alcohol for someone who is under the legal drinking age.
