I have never had a 'bad trip', or maybe I don't REALLY know what one is, but the only time I have CRAZY anxiety and super bad thoughts and stuff is when I am in fear of getting caught. School is the perfect place to get caught. At least at a mall or something you can go hide in a bathroom.
I have never "tripped" at school. But I did take a hit not to long ago. Nobody knew.I just laughed sooo much
If you think you can handle I say do it. I wish I had tried it when I was at school (I was blatantly high everyday though so I don't think I would have had to stress teachers or anything).
