One company known as the “Walmart of weed” is setting up shop in Washington D.C. a few miles in the White House and federal buildings.

The weGrow store will be opening on Friday in Washington, coinciding using the first concrete part of implementing city law to allow D.C. residents to buy marijuana for medical reasons.

WeGrow said hello offers the necessary tools to pioneers of a “green rush,” a movement it considers like the gold rush where nearly $9 billion could be made in the medicinal marijuana business within the next 5 years.

There happen to be 16 states that have decided to legalized marijuana for medical use to deal with a number of health issues, from anxiety and back pain to HIV/AIDS and cancer-ailments.

About 7 percent of Americans, or 17.4 million people, said they used marijuana in 2010, which is up from 5.8 percent in 2007, according to the Substance Abuse and Mental Health Services Administration.

A Gallup poll last year found that 50 % of american citizens state that marijuana should be made legal, and 70 % support medical uses for pot.

WeGrow does not sell pot or seeds to develop it, but it instead provides products and services to assist cultivators boost their own plants for personal use or sale at dispensaries.

The first weGrow store was initially opened in Sacramento this past year by founder Dhar Mann.  He said he started the store after he was kicked out of a mom and pop hydroponics store in California just for mentioning marijuana.

Since its opening, the store has opened an area in Phoenix, San Jose and Flagstaff.  It has also expanded in Nj, Delaware, and Pennsylvania.

WeGrow said it has intends to expand its business into Oregon, Washington State and Michigan too.

On Friday, D.C. officials will announce those who are eligible to make an application for permits to grow then sell medicinal marijuana to dispensaries underneath the district’s 2010 law.  Applicants must sign an argument saying they do know permission does not authorize them to break federal law.

“They are doing so at their own peril because I can’t imagine that the federal government will allow marijuana selling for just about any purpose right in their backyard,” Kevin Sabet, an old senior adviser towards the president’s drug czar as well as an assistant professor within the College of Medicine at the University of Florida, told the Houston Chronicle.

“Whether it’s D.C. or all the way out in California, the government’s been pretty clear that medical marijuana doesn’t pass the giggle test.”
