• Few birthdays are as important or as festive as your 21st. Turning 21 means becoming an adult and being old enough to buy and drink alcohol in the United States, so your gift could help your friend or loved one celebrate that milestone.
  
  

Disposable Cameras

• Since most 21st birthday parties involve alcohol, giving disposable cameras to the birthday boy and his crew can be an effective way of preserving memories while avoiding the potential tragedy of a broken digital camera or cell phone. After the festivities, collect the disposable cameras and have the photographs printed. Place the best photos in a scrapbook to create a gift that will be treasured for years to come.
  
  

Drink Recipe Book

• A drink recipe book is a fun and practical gift to give someone who has just become drinking age. No matter how much your loved one knows about mixed drinks there are sure to be several she has never heard of, and a recipe book can teach her how to make them for herself and others.
  
  

Wine Opener Kit and a Bottle of Wine

• Give your loved one a wine opener kit and a bottle of wine. Be sure to give your loved one a small lesson on opening a bottle of wine as it can be quite tricky if you have never done it before.
  
  

Personal Breathalyzer

• Now that your loved one can go to bars, help him avoid driving under the influence by giving him a personal breathalyzer. Though not as festive as other gifts, a personal breathalyzer could be lifesaving and shows you care.
  
  

A Hangover Care Kit

• Hangovers are an almost inevitable part of the 21st birthday experience. Create a care package for your loved one for the morning after her big day. Fill a basket with an eye mask, bottle of aspirin, beer and Bloody Mary mix, washcloth and a bottle of water.
