The test strips, for sure, may be given away. There are some jurisdictions where the pods (which contain insulin for those who don't know) are considered pharmaceuticals and access is restricted. However, in my opinion they're really only useful to someone else to use as pods. I wouldn't sell them; thst invites a whole bunch of legal (and moral) implications. But if you quietly give them away you should be fine. And thank you for thinking of doing that!
