Optimistic activists would say that the movement for marijuana legalization made a small gain last week when the Drug Enforcement Administration decided to expand marijuana research.

In fact, new research projects might be geared toward reaffirming rather than challenging biases against cannabis.

People flocked to Oregon's first-ever marijuana growers' fair on Saturday where a competition for best cannabis plants was being held, with the winners to be displayed at the Oregon State Fair.

The inaugural two-day Oregon Cannabis Growers' Fair underscores how the once-illicit marijuana industry is starting to go mainstream in Oregon, one of four states to have legalized recreational cannabis use, along with Washington, D.C.

A body of research suggests yes, but scientists are having to fight red tape to study whether medical marijuana could substitute for opioid drugs.

Taking your cannabis business to international markets can yield huge profits. After all, cannabis is completely legal in places like Canada, Jamaica, Colombia and Italy, and they don’t face the same tax, research and patenting issues as countries like the United States.

While going international with your cannabis brand might seem like a great idea, doing so within legal guidelines is not always straightforward and easy to do.

A bill currently on the desk of New Jersey Gov. Chris Christie's would add PTSD to the state’s list of qualifying conditions for medical marijuana.
