More than 20 states have approved marijuana use for medicinal purposes and Colorado and Washington are opening up the plant for recreational use. Marijuana companies rose more than 50 percent in 2013 and opened in 2014 with a bang, rising almost 150 percent in just three weeks.

This list gives an overview of publicly traded marijuana stocks worth over 50 million, including hydroponic companies, vaporizer producers, and research houses for medicinal purposes.

Medbox

Medbox (OTC: MDBX [FREE Stock Trend Analysis]) rose from $23 to $93 in a matter of five trading sessions, with the peak on January 8th. This is a great example of uninformed investors pouring their money into a hot name. The company makes automated dispensing solutions for medications, including marijuana. Medbox has the largest market capitalization of cannabis-focused stocks, close to 1.2 billion. It also does not file with the SEC.

AVT Inc.

Started in 2001, AVT (OTC: AVTC) began producing vending machines but recently transitioned to automated retail machines. Marijuana investors took interest in the stock when Medbox announced a purchasing agreement. Medbox spends about half a million dollars a year buying dispensary units from AVT.

Currently focused on Colorado, Advanced Cannabis Solutions (OTC: CANN) buys growing facilities and leases them to growers. The company looks for an ROI of over 25 percent and a ten-year deal for contracts.

Fusion Pharm

Fusion Pharm’s (OTC: FSPM) PharmPod product is a “plug-and-grow” hydroponics solution. The company looks to capitalize on commercial growers and small operations with its scaleable product. The company emphasizes that the PharmPod only requires 20 percent of the water of a more traditional growing solution and is very customizable. The company does not file with the SEC.

GW Pharma

GW Pharma (OTC: GWPRF) is one of the few cannabis stocks that trade on a major exchange (Nasdaq), meaning its financial information is much more closely regulated. The company is biotech, however, meaning it has its own set of risks. Based in the UK, GW Pharma is developing cannabinoid medications, primarily for multiple sclerosis and cancer. The company has one of the largest market caps at 930 million.

Hemp Inc.

With several nutrition products on the market, Hemp (OTC: HEMP) cannot seem to sell any of them. Using hemp as a key ingredient, its supplements seem to fall into three key categories: protein, sexual performance, and general nutrition. Hemp does not file with the SEC.

mCig

mCig (OTC: MCIG) has an interesting product: a ten-dollar mini vaporizer for bud and wax. Just over five inches long, mCig is very portable and even offers three different heat settings.

The second generation began selling at the start of the year. mCig does file with the SEC.

Medical Marijuana

Medical Marijuana (OTC: MJNA) produces a series of cannabinoid oil products, advertising the health benefits of consuming CBD. These include chewing gum, shampoo and lotion, and liquid CBD oil. CannaVest, mentioned above, was spun out from Medical Marijuana, which is now a minority shareholder.
