are stail brownies still potent?

Ok so I made a batch of hash brownies a week and a half ago. I forgot I had one left. Well i was looking around my car to see if i had any roaches because my stash ran out and I found the last brownie that i had in a bag under the seat. Well I just ate it so i've got about 45 minutes to an hour before i'll be able to tell if they work, but do you guys think it will still be able to get me high? I heated it up in the microwave for 20 seconds to try and freshen it up a bit, but it still tastes stail.

mine worked after a couple of days
one of my friends had hers for like a month and they still worked..

staleness shouldn't make ANY difference.. it's not like the thc would evaporate or disappear or something.
...lol unless it's like at the point of moldin or some shit

but u should still get high off'em. it just won't taste as good

i had a harrold's once for like a month!
it was so potent i would just rip off like a corner and be set for the whole day

should still work
