Smoking Before Donating Blood

Donating blood is a valuable gift that can save lives. In fact, millions of people in the United States need blood transfusions each year. If you’re a smoker, you might worry about whether you can smoke before or after donating blood. Major blood banks like the American Red Cross don’t have restrictions on smoking prior to giving blood, but they do have some recommendations regarding smoking after donating blood 3.


The American Red Cross and other major blood-bank institutions generally don’t prohibit you from smoking cigarettes before donating blood 3. But some blood banks advise that you not smoke immediately after giving blood. If you smoke right after donating blood, you’ll increase your risk of fainting or becoming dizzy, warns BioLife Plasma Services 4. Therefore, you should wait at least 30 minutes after donating blood to smoke a cigarette, advises the Gulf Coast Regional Blood Center 5.

In general, to give blood you must be healthy, at least 17 years old and weigh at least 110 pounds, according to the University of Pittsburgh Medical Center 1. A blood banking center will conduct a simple physical exam and assess your medical history. The American Red Cross typically determines your eligibility based on whether you’ve traveled outside of the United States to certain countries or continents recently, whether you have or have had certain communicable diseases and whether your lifestyle or health status makes donating blood unsafe 3. You might not be eligible to donate your blood if you’re at risk for passing on a blood-borne infection because you’ve used illegal intravenous drugs, or because you have been exposed to or currently have HIV infection, hepatitis, Chagas disease or babesiosis, or Creutzfeldt-Jakob disease.

Before Donating

Blood banks usually don’t have specific recommendations about smoking before donating your blood, but they do have other important advice. You should drink lots of fluids – more so than you normally drink – on the day that you plan to donate your blood, according to the American Red Cross 3. You should also wear comfortable clothing with a shirt that’s either sleeveless or has sleeves that are easy to roll up above your elbows. In the days or weeks beforehand, you can prepare to give blood by eating more iron-rich foods like spinach, fortified or enriched starches, seafood, meats, dried fruits and eggs. Get plenty of sleep and protein in your diet before giving blood as well, and avoid caffeine, alcohol and fatty foods immediately prior to donating your blood, advises BioLife Plasma Services 4. Remember to bring a valid form of identification like your driver’s license and a list of your current medications when you go to donate blood.
