Unfortunately, a newsweek article with anecdotal evidence and low external validity does not reflect reality. Prescription drug abuse is of course prevalent, but you're pretty out of touch if you believe kids are trading codeine and over the counter cough and cold medicines to get ahold of "good" drugs (i assume you mean prescriptions like oxycontin, vicodin, dilaudid, klonopin etc). I frankly don't believe that more kids are into prescription opiates and benzodiazepines than alcohol, which is a far harder drug than marijuana.
I'm not sure why you included that link to signs of methamphetamine use; nothing in your previous posts had anything to do with amphetamines (besides ritalin, which is an amphetamine salt and not methamphetamine).
EDIT: "-the drugs used to make a designer cocktail meth-head."
I'm still scratching my head as to what you mean by this.
och--
re-read the post. whatta think is happening to your pain relievers and non addictive drugs that you thought you had more of? (by you--I mean that generally-not your personally)
Kids are resourceful. They are smart. They know who sells, deals and looking.
They know who knows who.
So, easy to sell drugs on the blackmarket, to get cash or trade for what they want as a high.
It really is not a difficult concept.
The thing about the whole meth underground is that every user becomes a dealer as well.
