Hi, this happened to me multiple times, i had my plasting bag with nep in it and I needed to hide it so i put it in my sock the bag was closed a I sweat a bit, and then when insuflatted it my nose was very numb and uncomfortable and the effects were totaly different, i was 4 days up my parents didnt even noticed but then i became like zombie and they found out, that nep was totaly destroyed, i started seeing many people( halucinating) and it was totaly disgusting and that happened with more batches... 3 grams i dumped in toilet, next time i will hide it somwhere else, do you know why that happend? , is it because sweat or what? The bag was closed i think.
