  1. In 2019, the minimum age to buy tobacco was raised to 21.
    Prior to this, you only needed to be 18 to buy tobacco products in most states. Now, if you want to purchase and use tobacco products such as cigarettes, e-cigarettes, and cigars, you'll need to present a valid ID proving that you're at least 21 years old.[5]
    • Some U.S. states haven’t officially raised their own minimum legal sales age for tobacco yet, but they’re still required to abide by the new federal law.[6]

Stay at a 21+ all-inclusive resort.

Book a 21+ cruise.

PDF download Download Article
  1. Some “adults only” cruises are only available to guests who are over 21.
    These cruises are often designed to provide a more relaxing experience for older guests (or a more booze-y one, depending on the cruise). After you turn 21, you’re officially allowed to book a ticket for one of these cruises and enjoy the unique, child-free experience![12]
11

Attend 21+ concerts and events.

PDF download Download Article
  1. Some concerts take place at venues that require guests to be 21 or over.
    These venues often serve alcohol or function as bars as well, so they restrict entry to anyone under 21 in order to comply with the federal drinking age.[13] After you turn 21, you’re legally allowed to enter these venues, so you no longer need to worry about missing out on an awesome concert just because you’re too young!

Rent a car.

PDF download Download Article
  1. You’re allowed to rent a car at 21, but there may be extra fees.
    You may have heard that you need to be 25 years old to rent a car in the U.S., but this isn’t always true. To rent a car through the major car rental service Enterprise, you only need to be 21 years old. However, all drivers who are under 25 are required to pay a “young renter fee,” so it will unfortunately be a little pricier.[14]
13

Teach someone to drive.

PDF download Download Article
  1. In many states, you need to be over 21 to teach someone how to drive.
    This is because new drivers must earn their learner’s permit before taking their driving test, and these permits often require a licensed driver over the age of 21 to be in the car.[15]
    • Some states may require you to be older to teach someone to drive. In California, for example, a licensed driver over the age of 25 needs to be in the car with a permit holder.[16]

Become an Uber driver.

PDF download Download Article
  1. In many U.S.
    cities, you need to be 21 to be an Uber driver. Even though the legal age to get your driver’s license is 16, the ridesharing app requires that drivers be much older than this due to liability and insurance coverage. Depending on the city you live in, you’ll finally be allowed to sign up to be an Uber driver after your 21st birthday, which is a great way to earn some extra cash![17]
    • Unfortunately, if you live in California, you’ll need to wait until you’re 25 to become an Uber driver due to the extra high cost of insuring young drivers in the state.[18]
15

Become a bartender.

PDF download Download Article
  1. Most states require bartenders to be 21 or older.
    This makes sense, considering that you need to be at least 21 to consume alcohol yourself![19] If you’re over 21 and you’re interested in becoming a bartender, consider taking a bartending course. You’ll be able to decide whether it's the right career for you, and learn how to make some delicious cocktails in the process!
