Move over edibles, lotions and tincture potions — there’s an entire new realm of cannabis-infused products hitting the shelves of dispensaries and recreational shops as marijuana moves even further into the mainstream.

What was once almost always smoked is now also available to mix in with your morning smoothie, gargle as a mouthwash, or even insert into your, ahem, lady parts. The science of extracting THC to make the base oil used in many of these products is a fairly standard practice, which begs the question, “What can’t we infuse?”

As voters go to the polls this November, at least four states will consider ballot questions on marijuana legalization. Pending proposals in Nevada, Maine and California would authorize recreational marijuana use, while Floridians will vote on whether to allow medical marijuana use.

When young entrepreneur Steven Helfer put together a Facebook page about “dabbing” (smoking marijuana concentrate) featuring funny pictures, videos of people smoking and other pot-related content, he didn’t expect to get 110,000 “Likes.” And he didn’t expect to use it as a marketing platform to help launch a multi-million dollar business.

Drugged driving is a growing problem, police fear.

As pot dispensaries become more prevalent in Ottawa, there is growing concern about people driving while high.

In May, Canada’s leading drive-safe group held a series of meetings with new members of Parliament to discuss what it calls the need to implement better roadside testing technology, before legislation to legalize marijuana is passed.

Mothers Against Drunk Driving appealed to the government to do away with current drug-recognition evaluations, and implement “drug wipe” roadside saliva tests, similar to the Breathalyzer tests that detect alcohol, to tell on the spot whether a person is impaired by drugs.

Tech giants like Facebook and Google don’t allow users to post ads that sell cannabis or promote recreational drug use. But activists say these policies are inconsistently enforced, and lots of acceptable content gets blocked.

People who sell medical and recreational cannabis in states where it’s legal have become accustomed to seeing their social media pages go dark unexpectedly. Selling or using cannabis for any reason is still federally illegal, and companies like Facebook, Google, Instagram, and Apple remain wary of being held liable for the pot content they allow users to post and promote.

JUDY WOODRUFF: But, first: how science is increasingly considering the possibilities of medical marijuana as conventional medicine for some cases.

Science correspondent Miles O’Brien has the second of his two reports on this for our weekly series The Leading Edge.

MILES O’BRIEN, Science Correspondent: It’s a landmark place, and time, on the long road to bring medicinal marijuana into the scientific mainstream.

The New England Treatment Access, or NETA, dispensary in Brookline, Massachusetts, is housed in a Beaux-Arts bank building built in the 1920s, a cathedral of cannabis.

Paul Breeden has been coming here to treat chronic pain since the dispensary opened in February.

PEOPLE WHO WOULD rather ingest marijuana than smoke it have plenty of options. You can buy weed-infused pasta sauce, chewing gum, beef jerky… even vegan caviar. The edibles market is big. And this November, voters in California and several other states will decide whether to legalize the recreational use of pot—which means it’s poised to get a lot bigger.

The issue with edibles is their notoriously unpredictable user experience: They’re potent, take a while to kick in, and can take a long time for your body to metabolize. All that makes dosing an intimidating guessing game.

The lightweight panels are already being tested in a few high-end cars, including BMW, Audi and Mercedes Benz.

With a little elbow grease and a lot of ingenuity, a new Alberta business is churning out biodegradable auto parts made from wood, hemp and flax.

The BioComposites Group plant, located on Drayton Valley's Bio-Mile, uses a one-of-a-kind manufacturing process to make door panels, kick pads, cup holders and dashboard panels. 

"We take waste wood fibre and waste agricultural fibers, and then needle them together with a process that creates a mat that is used for interior panels," said Dan Madlung, CEO and co-owner of BioComposites Group.

“Imagine if you said to Paul Tagliabue, back in 2003, that Ricky Williams might one day be able to save Junior Seau’s life…”— Thoma Kikkis, co-founder of Kannalife Sciences

Imagine that it’s the year 2025. In locker rooms across the NFL, as ankles are taped and braces strapped on, trainers hand out gel capsules for players to ingest minutes before they take the field. The capsules are scientifically designed to protect against the deleterious effect of concussive blows to the head and traumatic brain injury—and, as a result, they have helped to sustain the viability of the sport of football. Oh, and yeah, they are derived from marijuana.

How – and why – online cannabis marketplaces will replace the black market.

The first thing ever bought or sold online was a bag of cannabis.

The deal went down in 1971. Decades before eBay or Amazon, back in the days when data was delivered in a shrieking telephonic trickle rather than a broadband light beam, the first thing ever traded online was cannabis.
