Hi Ann,
Welcome to our Community and how nice that you are planning a visit to the Emerald Isle!
After a quick search, I found out that prescribed cannabis-based products were not allowed in the Republic of Ireland. Here's
an official source with more details.
When it comes to other medicines, I'd suggest carrying them in their original, labeled containers with a prescription or doctor's letter. You shouldn't have any problems that way.
Are you already set on an itinerary? Let us know if we can help. 😊
Cheers,
Antoine
