Crowds from around the globe flocked to Tel Aviv in March for the second annual CannaTech conference. The summit was aimed at attracting fledgling marijuana ventures to the country and included speakers from medicine, politics, science, agriculture, and investments.

“Everything is set up here to be the epicenter of cannabis research,” organizer Clifton Flack told Quartz.

Why medical marijuana research is blossoming in Israel.

The Israeli government's stance on medical marijuana research and the country's cultural landscape make it far friendlier to marijuana than the puritanical policies of the U.S. government.

A new market report by University of Denver’s Daniels College of Business Assistant Professor Paul Seaborn finds that active marijuana business licenses in Colorado have hit an all-time high of 2,913 as of Dec. 1, 2016.

Canopy Growth Corp. (TSE:CGC), Organigram Holdings Inc. (CVE:OGI), and Supreme Pharmaceuticals Inc. (CNXS:SL) have all topped up their war chests this week with bought deal financings that put each of them in the rarified space among emerging public companies where they are able to attract seemingly endless amounts of capital at stout valuations with minimal dilution.

This year, the major accounting technology conference Accountex (formerly SleeterCon) happened concurrently – and down the street from – the largest cannabis industry conference in the United States, the Marijuana Business Conference and Expo. Seemingly an unrelated coincidence, the timing turned out to be kismet: Accountex attendee Penny Breslin, a financial technology consultant based in San Diego, found herself fielding questions from Expo attendees asking whether she “knew any good accountants.”

With the drug slated to be legalized in Canada in 2017, investors are rolling in, their engines sparked, hoping to take advantage of what some predict to be a multi-billion-dollar industry with 3.8 million recreational marijuana users in Canada by 2021. Factor in that the U.S. cannabis market is projected to rise from $6.0 billion in legal states in 2015 to $50.0 billion in 2026 according to data from Cowen & Co, and you have a lot of zeroes luring investors into marijuana stocks.

But for others, they’re worried that it could all just be smoke.

Florida's Health Department approved Knox Medical to be the fourth organization in the state to distribute low-THC medical cannabis.  The announcement came less than a month before the full legalization of medical marijuana in the state becomes effective.
