Brains, I've got my husband, who's a cardiologist, reading behind my shoulder. He says "none of those should give you any trouble if you mix them with grass. Those contraindication medications treat various things from skin conditions to heart and vascular diseases to infections to blood clots. THC in cannabis shouldn't be an issue with those." He just speculated that based on that list, you're being prescribed whatever you're newly taking for migraines, perhaps?
