Anything going to happen to me?!

I hope this is a joke. Otherwise, you'll get whatever is coming to you.

If she is aware that you did the drug then you may be suspended and there will be a discussion with your parents. If they are aware that you did the drug you need to protect others from the one who is not a friend. A friend wouldn't do this to another. You should tell them what was done so as not to have this on your conscience and know that you are helping other kids. I hope that and I do believe that you will never try drugs again.

If you feel different in as where you should start to see strange things, or hear different voices, obviously you will be tripping. The fact that you tried something different isn't necessarily a bad thing. As a human being, we are all inquisitive to different degrees. Back to the physical feelings. LSD acts differently on different people. One common way to bring yourself back is to flush your system with as much orange juice as you can drink. I hope this person claiming to be a "FREIND" is kidding, otherwise, you need some new friends.
Good luck

was it just normal paper? if so its unlikely that it was lsd.
lsd is hard to get hold of these days and your friend being able to find someone whos got a whole bottle of it (which would cost a HELL of alot of money) to just dip a piece of paper in it like it was nothing and then hand it over to you. it just doesnt sound legit at all your having a joke or he is one or the other.

You may see and imagine strange things for awhile.Maybe mild.
You should have this fool arrested,a friend does not give poison to another.
My friend died from someone lacing just marijuana with angel dust.
He killed himself.Get that bum locked up and learn a lesson.
bye

the nurse will probably ask you whats wrong and just say you don't feel good xD i highly doubt that he/she will check to see if you're on drugs.. unless you say you are
