Effects of snuff? need help?

ok well today me and my friends were eating lunch and (we r all in 9th grade) anyway my friend broughht in this like beef jerky stuff but its like all dried and shredded. and she asked me if i wantedf some so im like. uh sure. so i took like a pinchful and ate it but it tasted kinda weird. anyway so she starts cracking up laughing and im like what. and she just said nevermind. so she whispers something in my friends ear and my friend told me there was snuff in it and thats why she started laughing when i ate it. so she totally drugged me without me knowin and im mad cuz i dont do drugs. so i was wondering what the efects are in like a little less than a pinchful of snuff?
