A closed prison in California could soon house a plant for growing marijuana and producing cannabis oil. Southern California company Ocean Grown Extracts proposed a plan last month to transform an empty San Joaquin Valley prison, the Fresno Bee reported Monday. 

Cannabis legalization is coming in Canada and with it is coming a new business sector. Economic growth, tax revenue and job creation are the exciting upside of this emerging industry. What does this mean for jobs?

Let's look at a U.S. example. Colorado is one of four states with recreational cannabis sales and made $996-million dollars in tax revenue in 2015. That's almost a billion dollars, people! Along with that came a budding job market and a decreased unemployment rate.

Types of Jobs

Like other businesses, the cannabis industry will have a need for traditional roles in areas like finance, marketing, human resources, operations and IT.

As commercial marijuana grows in Colorado continue to receive plant quarantines and product recalls over the use of potentially harmful pesticides, herbicides and fungicides, one industry group is trying to set up a way to ensure safe growing practices. The Organic Cannabis Association's pesticide-free certification program will test participating grows for residuals of harmful pesticides and award scores based on the products used at the grow.

"We view cannabis producers as just another set of farmers," says John-Paul Maxfield, chairman of the OCA. "This is our first step toward building a larger organic certification."

SAN FRANCISCO (KGO) -- Thanks to changing federal and state regulations, the marijuana industry in California is booming. And now women are taking the lead and breaking through the "grass ceiling.

Weed, pot, marijuana, Mary Jane, no matter what you call it - the sale of legal cannabis is growing fast.

Industry leaders expect sales to soar from $2.5 billion in 2014 to as much as $8 billion by 2018 and women are staking claim to many of those new businesses.

"Women are natural healers," Andrea Unsworth said. "We're the people who are typically in your home when you are sick, you know you go to mom."

How to make pot seem as all-American as an ice-cold beer.

Colorado cannabis regulators on Monday recalled medical and recreational marijuana grown by two cannabis businesses — RR Services and Advanced Medical Alternatives — over concerns the plants were grown with unapproved pesticides.

The recalls, called health advisories by the state, are the tenth and eleventh holds announced by the Colorado Marijuana Enforcement Division in less than one month.

The advisories note that 42 batches of RR Services’ marijuana and 10 batches of Advanced Medical Alternatives’ cannabis each tested positive for myclobutanil, a fungicide considered “slightly hazardous” by the World Health Organization and a “Bad Actor” by the Pesticide Action Network.

The marijuana industry may be growing rapidly, but if you don't know these critical points, your investment in marijuana stocks could go up in smoke.

It may not rank up there next to Social Security or Medicare, but marijuana is getting itself a lot of coverage this election season -- and for good reason.

The weed business is booming.

In its annual report on the U.S. cannabis industry, Marijuana Business Daily predicts up to $44 billion in economic impact by 2020. To put that into some corporate context: it's roughly equivalent to the current market cap of Netflix (NFLX) or Caterpillar (CAT). Last year's report predicted $14 billion to $17 billion in impact for 2016. The publication has been producing the report since 2012.

You won't find brightly coloured bongs or bubble gum-flavoured rolling papers displayed against the backdrop of exposed brick and modern, industrial-style furnishings at Tokyo Smoke.

Instead, the shop — located in a former shipping dock nestled between two warehouses in Toronto's west end — carries high-end pot paraphernalia befitting the pages of a design magazine while also serving up cups of artisanal coffee.

Pipes handcrafted by California-based ceramicist Ben Medansky sit alongside a pricey portable vaporizer, a reimagined version of the French press coffeemaker launched via a Kickstarter campaign and a selection of what shop owner Alan Gertner calls "museum quality collectibles" — items such as vintage Barbies and a vintage Hermes bag.

Renowned scientist Dr Henry Lowe has pointed to the huge foreign exchange potential of nutraceuticals and medical cannabis and says that Jamaica needs to move quickly to capture its share of what is a rapidly growing global market.

“With limited effort, there is an estimated potential earning of over US$300 million from these two products in the next three years if the products are properly marketed,” Lowe, who has developed a number of nutraceutical products using Jamaican plants, told the 50th anniversary annual general meeting of the Jamaica Exporters’ Association last week
