Millions of Americans can now get medical weed under state law, but we still haven't done much research into the drug's positive effects.

The federal government has a "responsibility" to facilitate sensible research into marijuana's medical benefits, Sen. Elizabeth Warren (D-Mass.) and seven other senators urged in a letter issued last week to multiple federal drug and health officials.

The Colorado Board of Health will hold a meeting tomorrow that could result in another affliction being added to the Medical Marijuana Registry's list of debilitating conditions.

A new study published The American Journal of Drug and Alcohol Abuse has found that teens are using marijuana less frequently and are less attracted to it now that it is decriminalized or legalized at the state level. 

The data challenges many assumptions about how changing cannabis laws may impact children. 

Opponents of legalization often tout scientifically unsupported notions about teen marijuana use. 

A bill to establish Hawaii’s first medical marijuana dispensary system will become law at midnight Tuesday, with or without Gov. 

The Sacramento County Board of Supervisors voted unanimously Tuesday to continue the urgency ordinance on medical marijuana dispensaries until July 27.

Sacramento County Supervisors voted Tuesday to revise its water code to declare marijuana cultivation a form of water waste.

The Board of Supervisors unanimously agreed with the proposal, set forth by Supervisor Roberta MacGlashan, in light of the state's years-long drought.

"According to the California Department of Fish and Wildlife, a single marijuana plant uses an average of six gallons of water per day during the growing cycle," MacGlashan said after the hearing.

The supervisors cited recent examples of pot busts to show how much water is being used.

Nick Lachey, a member of the band 98 Degrees and more recently a television actor, is among five investors in a Hudson marijuana grow center, one of 10 that would be created across Ohio under a proposed ballot issue.

While marijuana taxes earmarked for schools soared in May, recreational pot sales in Colorado plateaued in spring 2015

​The Colorado Department of Revenue’s just-released marijuana tax data for May 2015 shows one clear winner: schools.

In the first five months of 2015, the state’s pot-funded excise tax that collects money earmarked for school construction capital brought in more money than it did in all of 2014. While that specific school tax’s 2015 take may not reach the $40 million number used to lure voters toward the state’s pot-legalizing Amendment 64 in 2012, its recent growth is exciting to lawmakers and industry alike.
