Hash cookie help

so i got some hash cookies the other day. i ate one each day since then and havent gotten stoned at all from them. I ate just one cookie each time and after waiting for 2 hours each time nothing ever happened... wtf? I talked to the guy i got them from and he said he had eaten 2 after meeting me and was ripped. So, ive only had edibles twice before but I smoke/vape everyday so dont know if that makes a difference as far as tolerence goes. Also, after waiting two hours would i be fine to try another? :smokin:

maybe you should try eating at once, if you dont feel anything with one, double it, whats the worst that could happen, you'll throw up, then it would be like you ate one good cookie, and you will get something instead of 2 nothings. or nothing happened. in which case, id get your money back.

thats the bad thing about edibles, you cant really tell if they are real all the time or not, even if there is plant material in there, it's hard to tell what is weed and what isnt sometimes even when you see it.
