Drug use (recreational)

Can I still donate blood even if I have taken recreational drugs?

If you have ever injected drugs not prescribed by a registered medical practitioner, even once, you will not be able to give a blood donation.

  • People who have injected drugs have a high risk of having a number of virus infections, especially hepatitis C.  
  • This and some other viral infections, may be life-long.  Not all viruses can be detected by our blood tests.  
  • NZ Blood Service cannot collect blood that contains any recreational drugs since these might cause adverse effects in the donor while the blood is being collected.  In addition some drugs may harm people who receive the blood.


NZ Blood Service values the privacy of donors. All interviews are held in private and donor confidentiality is always maintained.

Please call your local Donor Centre or 0800 GIVE BLOOD (0800 448 325) and ask to speak with a nurse if more information is needed.
