"I acquire quite a few medications and then dispense them to my friends as needed."

Says Katherine: "I usually know what I'm talking about." This is, apparently, a big trend:

For a sizable group of people in their 20's and 30's, deciding on their own what drugs to take - in particular, stimulants, antidepressants and other psychiatric medications - is becoming the norm. Confident of their abilities and often skeptical of psychiatrists' expertise, they choose to rely on their own research and each other's experience in treating problems like depression, fatigue, anxiety or a lack of concentration. A medical degree, in their view, is useful, but not essential, and certainly not sufficient.

They trade unused prescription drugs, get medications without prescriptions from the Internet and, in some cases, lie to doctors to obtain medications that in their judgment they need.

Oh, these young people. They used to just smoke marijuana.
