Medical Marihuana – can I travel to other countries and legally take my Medical Marihuana with me within European Union, like Portugal?

Good day!

I am undertaking a medical marijuana treatment for several months now, I am based in Poland, I need to travel to Portugal. Am I allowed to bring my MM to Portugal via plane? I know Portugal has descriminalized EVERY drug possession but I want to make sure I am not violating any law.

Any advice will be appreciated.
