Can I donate blood if I use cannabis?
What this means
- Past or occasional use is not a barrier.
- You must be sober and able to give informed consent at your appointment.
- Avoid using right before you donate.
What to do next
Book for a time when you will be clear-headed and feeling well.
When to call the center: No need to call about cannabis use specifically.
Why this rule exists
You need to give clear, informed consent, which is why impairment is the issue, not the substance.
This is general educational guidance, not a final eligibility decision. Donation centers make final eligibility decisions during confidential screening. Rules may vary by center, donation type, location, and current policy.
