I was half way through a long train trip and ran out of weed. I asked a couple if they had any weed to spare for pain. The woman gave me a small package and told me to be careful as it was really strong. Her boyfriend seemed disapproving. The package contained a nasal spray of 4mg of narcan and a single gell pill containing a white powder. I didnt use it yet and brought it home. I am wondering how to test it to find out what it is. I have looked at test strips online, but the variety has scared me off ( and cost). What would be the simplest, most cost effective way to test? I cannot afford a bunch of expensive test kits. B4 telling me to just toss it, I've had it for awhile and I'm pretty curious as to what I've got. I normally use weed, and psychedelics, with a side of kratom, or ghost pipe for good measure. Open pill and just taste seems like it might work. But, the free narcan has me cautious.
