You and your roommates have decided to go to a fraternity party on Saturday night. You arrive at the fraternity house and see another classmate, Jenn, from your psychology class. You go over to say hello and see what she thought of the first exam, but Jenn seems to be acting very strangely. She starts describing fantastic colors made by the lights and how the dance floor is a beautiful sea of diamonds. You take a look around and realize the lights are nothing special, while the floor is definitely made of wood. You take another look at Jenn; her pupils are dilated and she keeps hugging everyone. When she comes over to hug you and tell you how much she's missed you since yesterday, you observe that Jenn is sweating and clenching her teeth. Additionally, you can feel her heartbeat when she makes contact with you. What drug has Jenn taken?
