San Diego voters will be told this fall that passage of a ballot measure to tax businesses selling recreational marijuana could generate an estimated $22 million for city coffers in the first year, according to documents made available Tuesday.

The estimate is part of a fiscal analysis of Measure N, which will go before voters in November. The City Clerk’s Office released fiscal and legal analyses on the dozen city of San Diego propositions that will be decided in the general election.

Measure N would only take effect if voters statewide approve Proposition 64, which would decriminalize recreational marijuana use. The drug is currently allowed under state law only for medical purposes.

Zinc deficiency is addressed by all the usual ganja guru suspects whose cannabis cultivation advice I respect and have learned from in books, magazine articles, live lectures and internet postings. Their observed symptoms of interveinal chlorosis, edge and spot necrosis plus stunted new growth seem to me more the result of near or complete absence of zinc rather than a mere “deficiency”. After reviewing the literature, I’ve come to believe that zinc deficiency in cannabis is a very common yet silent suppressor of optimum yields. In food agriculture, crop yields can be attenuated by over 20% without any symptoms at all of zinc deficiency being visible; this can go on for years and you’d never know it.

The Foundation of Cannabis Unified Standards (FOCUS) is working to create order among the chaos caused by a cannabis regulatory contradiction. FOCUS, which is an independent, third-party, not-for-profit organization, is in the process of developing cannabis-specific standards for everything from cultivation and extraction to packaging and retail.

FOCUS Founder and Executive Chair Lezli Engelking says the overall goal is to help growers implement these standards, which were developed by industry professionals who reached a complete consensus on each approved product and reflect what is safe to use on other agricultural and plant products, by providing guidance.

Sometime in the middle of the afternoon on April 26, Luis Hernandez-Gonzalez, the 44-year-old owner of a hydroponics gardening store in Miami, Florida, received a call from a customer who had recently moved to Tennessee.

Luis Rego, a 32-year-old alleged pot farmer, was having trouble with his current crop and wanted some advice. Unbeknownst to both men, special agents from the US Drug Enforcement Agency (DEA) were eavesdropping on their conversation as part of an investigation into a ring they believed had set up an illegal grow house network in eight Tennessee counties. According to an excerpt from transcripts of the phone call, Rego said of his crop, "Man, this does not want to even out... In the morning, it's fine, and in the afternoon, it gets sad."

The state's medical cannabis commission plans to reveal its rankings of prospective growers and processors this week, as complaints mount about the lack of diversity among the winning companies.

Dr. Paul Davies, chairman of the medical cannabis commission, said the selections were made without commissioners knowing the identity or background of the applicants. He said he's "very happy" that some of the winning companies are run by women or racial minorities.

Racial diversity was was not a factor in deciding which applicants were awarded licenses to grow and process the drug this month.

From APIs to dispensary robots, new innovations are popping up like weeds.

The cannabis industry is growing up, and it would be tough to imagine more convincing proof than Microsoft's recent announcement that it's getting involved.

Though the software giant will stay very much in the background -- its role will focus primarily on providing Azure cloud services for a compliance-focused software push -- the move is still widely viewed as a telling sign.

For all the buzz it’s generating, legalized pot may not live up to the hype. At least not in Uruguay where limits on production and pricing have led one of two producers to diversify into less regulated hemp.

Weeks before selling its first ounce of pot at pharmacies, International Cannabis Corp. is already betting that hemp - a variety of cannabis - will be a much bigger market than selling the psychoactive part of the plant, according to Chief Executive Officer Guillermo Delmonte. Hemp and its extracts can be used in food, cosmetics and medicine.

If the idea of lacing traditional Jewish foods — gefilte fish, challah, matzo balls, latkes and kugel — with marijuana makes you wince, then skip right over this. But if reading about what certainly must be the first cookbook to feature such dishes piques your interest, read on.

All of these Jewish classics and more can be found in “The 420 Gourmet: The Elevated Art of Cannabis Cuisine” by JeffThe420Chef (Harper Wave).

Rolling a five pointed joint is one innovation, but science is finding many new high-tech ways to help cannabis patients.

When it comes to technological developments in the widely varied cannabis industry, some come about due to the natural instinct to innovate, and some come about as a necessity to adapt with the ever-changing landscape that is the medical and recreational cannabis space. Over the years, businesses, researchers, advocates, and everyone in between has had their crack at assisting in ushering in new technologies and practices.
