Foster care can be a dangerous place for children. Foster children may be neglected, injured, sexually and physically abused, or even murdered by foster parents. But for foster children living in medical marijuana states, often the greatest danger can be CPS itself.

Every single one of the 20,000 people who march through Golden Gate Park during the annual AIDS Walk on Sunday will be exposed to marijuana. 

There will be no choice — the cannabis industry has sponsored one of the checkpoints. The water, the tents, the DJ booth, that's all paid for with volunteered cannabis cash.

"We're trying to have a presence here," says Christopher Esposito, a former board member of the SF AIDS Foundation who's now running the "Team Cannabis" fundraising cadre at the walk. "It's the Gap, it's Chevron — and it's Team Cannabis."

And in some instances, cannabis's activist streak is winning, handily.

Members of Congress are often eager to admit they're not scientists. The trouble is, they also don't like listening to scientists and have tried to keep them from shaping federal policy on issues from national defense to environmental protection to gun violence. Now, America's ignorance-is-bliss Congress has come to fear what scientists might have to say about marijuana.

If you happen to see a robot on the side of the road this summer, don’t be afraid to pick him up. That’s just hitchBOT, a friendly hitch-hiking robot trying to make his (her? its?) way from Boston to San Francisco.

Designed by Canadian researchers, hitchBOT is part art project, part social experiment. Can robots trust humans? Or, perhaps more importantly, can drivers trust hitchBOT?

If you see hitchBOT along the side of the road or outside a coffee shop, you’re free to take him with you. He just wants to see the country — from Times Square to the Grand Canyon, and everywhere in between. HitchBOT can’t move on his own, so once you get tired of dragging him around, feel free to pass him off to a friend or stranger. Or just leave him out in a public place.

Denver is scheduled to air its first marijuana commercial on Monday, July 20, and the nation’s budding pot industry couldn’t be happier, despite recent high-profile drug busts.

With recreational marijuana use legalized in four states and the District of Columbia, and ten other states considering it, the newly minted industry is slowly being accepted by the general public.

Soon after her first birthday, Mallory Minahan began suffering from debilitating seizures. For a decade she suffered these attacks—a symptom of intractable epilepsy—as many as 30 or 40 times a month. Her parents, both medical professionals, were powerless to help.

With widespread anticipation that California voters could legalize recreational marijuana use for adults next year, a generation of women growers are poised to shed the term “activist” for “CEO.”

About two dozen women working in the North Coast’s flourishing medical cannabis industry will be rubbing elbows after business hours Thursday in downtown Santa Rosa during a launch party for a local chapter of Women Grow, a for-profit networking company.

The women say they aim to break through what some call the “green ceiling” of an industry traditionally run by men, with marketing heavily skewed toward able-bodied heterosexual males.

There really is a subscription box for everything nowadays and that includes marijuana.

Beauty enthusiasts have Birchbox. Dogs and their people have BarkBox. Men who don’t embrace their 5 o’clock shadows have the Dollar Shave Club. Foodies and drinkers have as many options as there are months in a year.

And now medical marijuana users in California have at least two choices: PotBox and Marvina.

Through its curated monthly subscription service, PotBox is hoping it can make ethically-sourced farm-to-bong pot as popular as ethically-sourced as farm-to-table food.
