As more states decriminalize recreational use of marijuana and expand its medical applications, concern is growing about inconsistent and inaccurate dosage information listed on many products, including brownies and other edibles. But now scientists report that they have developed a technique that can more precisely measure cannabis compounds in gummy bears, chocolates and other foods made with marijuana. They say this new method could help ensure product safety in the rapidly expanding cannabis retail market.

The researchers present their work today at the 251st National Meeting & Exposition of the American Chemical Society (ACS).

TEL AVIV (JTA) – He was chilling out in the corner, tipped back in his chair, newsboy cap askew on his head, a grin on his face and smoke gently wafting from his mouth.

Finally, I thought, I’ve found someone smoking pot at a cannabis conference.

CannaTech, an international conference held for the first time last week at venues in Tel Aviv and Jerusalem, featured seminars on everything from the global cannabis investment market to quality control in commercial cannabis cultivation. There were vendors showcasing the latest growing technologies and unique handmade smoking devices. One guy was even touting a product to alleviate the dry-mouth feeling stoners are all too familiar with.

Because he’s a scientist, not a back-slapping venture capitalist, Mowgli Holmes loathes using the term networking to describe even the portion of his job that entails shaking hands in the cannabis industry. But it was networking that brought the chief scientific officer of Phylos Bioscience in Portland, Oregon, to Las Vegas in November 2014 to attend the Marijuana Business Conference and Expo—and to smoke a massive joint with one of the cannabis movement’s legends, Ohio lawyer Don Wirtshafter.

Could technology which detects when you are distracted at the wheel save lives?

Major automakers are investing in car monitoring systems which detect when you are distracted or too tired to drive effectively.

According to the Wall Street Journal, a number of high-profile vehicle manufacturers are investing and testing driver monitor systems which keep an eye on your movements and body readings, in order to give you a nudge or alert you when your focus is faltering.

“As much as we love cannabis, this is a non-consumption event.”

That admonition kicked off the first day of presentations and roundtables at Cannatech, a three-day conference on the marijuana industry held this past week in Israel. Instead of pot edibles, hundreds of attendees munched on pita sandwiches and Turkish bourekas.

And, save for occasional patches of pungent air, the request to keep the event sober mostly worked.

Starting your first cannabis garden can be overwhelming -- there are endless opinions on what equipment to use and which techniques yield the best results. Fortunately, there are a lot of ways to grow great cannabis. With a little homework, a spirit for problem solving, and some memory of your high school science classes (don't worry, just some), you'll find that growing cannabis is one of the quickest and most impactful ways to deepen your understanding of this unique plant.

Leafly visited five different gardens to get a behind-the-scenes look at how the professionals are growing cannabis. We'll bring you to indoor facilities in California, Colorado, Oregon, and Washington to study the steps successful growers use to produce some of the finest flowers in the country.

Starting this summer, medical marijuana products will be required to undergo testing by certified facilities, much the way that recreational products are currently tested. Last week the Colorado House passed House Bill 16-1064, which will enable facilities to get a medical marijuana testing license in anticipation of that testing, and the state Senate passed the proposal on March 8.

Magic things happen when you get down to the nanoscale. Suspensions of gold or silver particles change colors; calcium carbonate molecules can be arranged to either produce beautiful opalescent abalone or dusty chalk. The way things are put together is the difference between coal and diamonds, so what has scientists so excited about hemp nanotechnology?

Why hemp?

The Startup Nation’s Tel Aviv hub opened its doors on Monday to Israel’s first ever international conference on innovation in the medical cannabis industry.

Founded just last year, CannaTech’s conference brings together experts and entrepreneurs from across the field, including growers, researchers, investors, and others that have been drawn to this rapidly expanding field.

Second annual CannaTech conference brings hundreds of delegates from 15 countries to see what Israeli ‘cannapreneurs’ can offer them.

Marijuana conferences are popping up on a near weekly basis in the United States. Entrepreneurs, scientists and investors have to weed out the recreational gatherings from the more important industry confabs.

But there was no doubt that the CannaTech 2016 International Summit on Cannabis Innovation this week in Tel Aviv and Jerusalem was an essential event.
