Excellent question, Heather.
While this is not my area of expertise, I understand that
Traveler Health is definitely a priority for both our visitors and medical personnel here.
The rule of thumb is if you’re bringing medicines with you into Ireland, carry them in their original, clearly labeled container, along with your prescription or a letter from your doctor. Anything over a three-month supply of medicine will be questioned and any “controlled drugs” as well as any syringes or needles, should be declared and explained in a letter from your doctor.
Might others in our Community have experience traveling with CBD oil, and offer their knowledge?
