Is poppy tea better for your health then prescription painkillers? like coca leaves being a lot safer and healthier on the body than pure cocaine

That is hard to say: since I don't know where you are buying these poppy leaves,(I don't know what is in them besides poppy) My suggestion is to take prescription meds are prescribed. To try other things for pain like distraction, humor, movies, reading, and ask doctors in Sweden what is recommended for your medical conditions. You don't state that in this. Good luck and don't give up.
