too hard to tell but if you kept it in a air tight jar it's fine but if it was just sitting out in the bag i'd toss it.
Doesn't matter honestly. I'd smoke it. I've smoked 2-3 month old weed and it got me high as fuck lol. Was only mids too!
When you break it up is there like a powder like substance that puffs off of it? Any moldy bud I've ever gotten had dried out and when you broke it up puffs of powder would emanate from it.
Use some small nail scissors, perfect for cutting weed carefully, and it doesnt fly everywhere. From the pictures you posted (which are not good, btw) it looks like mold. i wouldnt smoke it. You can maybe make an extract using alcohol though. Im not sure, but i think alc will kill the mold[dont quote me]. DO NOT SMOKE IT
How can you not know if there is mold on it? Look at pictures of moldy weed on google or something. you will know.
