weedlineThe New York Times reports on a, er, teen health trend:

At the Peace in Medicine Healing Center in Sebastopol, the wares on display include dried marijuana — featuring brands like Kryptonite, Voodoo Daddy and Train Wreck — and medicinal cookies arrayed below a sign saying, “Keep Out of Reach of Your Mother.”

The warning tells a story of its own: some of the center’s clients are too young to buy themselves a beer.

Several Bay Area doctors who recommend medical marijuana for their patients said in recent interviews that their client base had expanded to include teenagers with psychiatric conditions including attention deficit hyperactivity disorder.

“It’s not everybody’s medicine, but for some, it can make a profound difference,” said Valerie Corral, a founder of the Wo/Men’s Alliance for Medical Marijuana, a patients’ collective in Santa Cruz that has two dozen minors as registered clients.

“How many ways can one say ‘one of the worst ideas of all time?’ ” asked Stephen Hinshaw, the chairman of the psychology department at the University of California, Berkeley. He cited studies showing that tetrahydrocannabinol, or THC, the active ingredient in cannabis, disrupts attention, memory and concentration — functions already compromised in people with the attention-deficit disorder.
