The Bay Area's well-developed medical marijuana industry has done much to elevate the age-old practice of smoking marijuana to new heights, with sticky, stinky new strains and a wide variety of edibles. Along with improvements of the herbal variety have come winning technological advances: the formulation of some mighty fine of cannabis tinctures and other concentrates. Our favorite? Alta California tinctures by CBD Science, formerly known as 420 Alchemy. Take a drop or two sublingually (that's under the tongue, stoners) and you'll attain a beautiful high that's different from smoking, vaporizing, or eating — a clear but consuming ride that seems to emanate from your very tissues, almost ecstasy-like. Three varieties — Healing, Tranquility, and Euphoria — give fans a range of satisfaction.
