Yikes!!
Why would anyone want to take something that has such a bizarre recent track record? The symptoms don't sound like something you would want to try; agitation, paranoia, suicidal tendencies. Why would anyone think these symptoms couldn't happen to them?
They don't think and don't care. They're looking for a high, a thrill.
Years ago, I worked in a state office. Full of people with advanced degrees. Eventually we started to realize that our purses/desks were being rifled through and what was being stolen was ANY kind of drug we might have in our desk. (It wasn't uncommon for people to have drugs because our health plan's pharmacy was in the lobby -- so people often picked up their family's prescriptions on break/lunch and then had them in their purse/desk.) We finally found out what was happening when a long-time employee actually asked one of -- begged to be exact -- if she could have one pill from the prescription bag she saw the coworker putting into her purse.
Her: "Can I have one of those? Please? Please?"
Coworker: "WHAT?"
Her: "Can I have one of those pills? Please? I want one. Please. Can I have one?"
Coworker: "NO! What's wrong with you? Who asks someone for a pill?"
Her: "I want to try it. I want to try it."
Coworker: "You don't even know what it is!"
Her: "I don't care what it is. I just want to try it."
Coworker: "Really? You don't care what it is? It's a drug for my son's encopresis!"
Her: "I don't care. I just want to see what happens to me when I take it."
Coworker: "You'll have an accident in your pants is what will happen, you idiot!"
Coworker: "I just want to try it."
Well, needless to say, her boss and HR were called in and she was gone by day's end. Come to find out, she had a well-hidden addiction problem and what she was really addicted to was using drugs to "feel something." She said she felt "dead inside" except when she used drugs to "feel something." So she didn't actually care what the specific result of a drug was, as long as it was SOMETHING.
