Psychoactive Drugs and Their Effects on the Brain
Psychoactive Drugs and Their Effects on the Brain
Your roommate Gretchen has had chronic pain issues since she broke her back in a car accident about a year ago. You know that she finished her prescription pain killers at least three months ago, but you’re suspicious she’s been taking something else. Quite frequently you find Gretchen passed out in her room, and when she is awake, she doesn’t seem to care about much. She stopped going to class and says her pain is way better than it was a few months ago. You got really worried last week when you found a syringe laying on the bathroom floor and then found out from your landlord that Gretchen never paid her share of the rent. What drug is Gretchen on?

You made plans with your friend Jason to order some pizza and watch the new Transformers movie. When you arrive at Jason’s apartment you smell a distinctive odor in the hall. When you open his door, a smoky cloud lingers in the living room. Jason has invited his cousin Max over and they seem to have been smoking something. Their eyes are red, they seem extremely relaxed, and there are food and candy wrappers all over the place. Jason says that he totally forgot you were coming over, but you should stay and hang out anyway. What have Jason and Max been smoking?
