After Nov. 8, when voters in nine states will consider some form of cannabis legalization, the cannabis stock investment market may explode. If you’re feeling like you’d like to get in on the ground floor, consider Nov. 9 the day the street-level doors will be barred.

Want to jump in now? Be careful. Investors are already rushing into the market. Marijuana-related equities have, on average, more than doubled in price since September 1. Many of those stocks are extremely volatile, however, and may plummet just as quickly as they’ve risen.

As legal marijuana becomes more popular in the US and abroad, people are coming up with creative ways to capitalize on the trend.

Here's a look at some very interesting ventures in the cannabis world.

Forget 1-800-Flowers.Com Inc (NASDAQ: FLWS), it's Buds & Blossoms’ time now. This Denver-based florist that specializes in pot-infused weddings takes buds "Straight from your bouquet to your bowl.” Owner Bec Koop was featured on CNBC’s Strange Success segment earlier this week.

Although the sale of marijuana is a federal crime, the number of U.S. banks working with pot businesses, now sanctioned in many states, is growing, up 45 percent in the last year alone.

Still, marijuana merchants say there are not nearly enough banks willing to take their cash. So many dispensaries resort to stashing cash in storage units, back offices and armored vans.

Proponents believe the Nov. 8 election could tip the balance in favor of liberalizing federal marijuana laws, a move seen as key to getting risk-averse banks off the sidelines.

Vancouver-based Aurora Cannabis (TSXV:ACB) today reported its fourth quarter and fiscal 2016 results, and though the company posted a hefty loss it predicted better days ahead.

For fiscal 2016, Aurora lost $5.7-million on revenue of $1.4-million. The company posted no revenue in fiscal 2015, as it only began to sell medical marijuna products on January 5 of this year.

Aurora CEO Terry Booth characterized the year, one in which the company raised $68-million, made what it feels were key hires, and strengthened its board.

Growing cannabis legally will be a step closer on Sunday when federal legislation comes into effect allowing the drug to be grown for medicinal purposes.

The Office of Drug Control will start accepting applications for cannabis cultivation licences on Monday.

People or organisations wanting a licence will need to show they will be supplying either a licensed medicinal cannabis manufacturer or researcher.

How well do you know your weed? A Berkeley laboratory recently found that 84 percent of medical marijuana samples contained large amounts of pesticides. Steep Hill, a Northern California-based cannabis testing lab, says their findings were much higher than expected and “are cause for concern for California cannabis consumers.”

“Those in the cannabis community who feel that all cannabis is safe are not correct given this data – smoking a joint of pesticide-contaminated cannabis could potentially expose the body to lethal chemicals,” says Jmichaele Keller, president and CEO of Steep Hill. “As a community, we need to address this issue immediately and not wait until 2018.”

Creso Pharma Ltd (ASX:CPH) has partnered with Swiss pharmaceutical firm, Streuli Pharma, to commercialise its first human nutraceutical product, INNutri Soft Gums in the Swiss market.

Creso’s strategy is to develop and commercialise pharmaceutical-grade cannabis and hemp-based products for the nutraceutical (food supplement) market.

INNutri Soft Gums use an innovative and proprietary delivery technology allowing for an optimum delivery of cannabis and hemp derived therapeutic products.

The cannabis is delivered through buccal (mouth) absorption and the soft gums have several advantages over existing health supplement products.

Tokken is a mobile banking app designed to legitimize the way Coloradans pay for weed. Using a custom-built internal banking system based on “tokens,” instead of cash, the company hopes to grow the technology and, eventually, disrupt the global banking system.

For users, Tokken acts as a digital wallet, enabling easy purchasing with on-file cards. But this wallet is different from other popular payment systems, like Venmo or Paypal.

Tokken’s technology converts hard currency to digital tokens, which are used as an accounting tool, linked to U.S. currency.

Dispensaries can choose to leave the money in token form, convert tokens to cash or use them to make other payments.

Cannabis has been part of human culture for millennia, and is still an important part of the day-to-day life of millions of people worldwide. However, in much of the world, a century-old stigma has established a harsh legal and social climate for the recreational and medical use of the substance. The current legal status of marijuana is extremely complex; in most countries it is illegal to grow, sell and carry the plant and consumption can carry the confusing label of ‘illegal but decriminalised’. Despite these barriers, in recent years a handful of countries have taken decisive steps to become marijuana-friendly territories. Cannabis legalisation advocates have pushed this agenda for decades, but it seems like it has gained institutional acceptance only in recent years.
