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.
