Losing a child is the worst nightmare any parent could imagine, a nightmare that is much harder to bear when you know that there may have been something you could have done to prevent such an awful tragedy. As unimaginable as this scenario is for most parents, preventable deaths are happening at an alarming rate as politicians argue about whether or not marijuana is medicine (we did some checking, it is). At this crucial time in history, a moment when the science on medical marijuana has become crystal clear, our government leaders can no longer afford to move slowly on reform measures. The lives of our children depend on this.

Master P and Silkk The Shocker aren't the only ones looking for weed to make money anymore.

Marijuana is legal for adult use in two states and available to medical patients in almost half the country, and legal sales generated over $2 billion in 2014. But a regulated pot industry could unltimately generate $45 billion annually if marijuana is legalized nationally, according to an industry study published earlier this month.

As parents of disabled and deceased children told heart-wrenching stories Monday morning, Sen. Kirsten E. Gillibrand had to stop and compose herself.

The emotional pain the families of brain-impaired children recounted would not be necessary, she told a news conference at the Dent Neurological Institute in Amherst, if medical marijuana were available like other regular prescription drugs. But because the federal government still looks upon the substance as a harmful and illegal drug akin to heroin and LSD – even where it’s legal – she said more children with neurological disorders will continue struggling with damaging daily seizures.

Medical marijuana users in Quebec can now help shed light on the drug's long-term safety and effectiveness through a new registry at McGill University in Montreal. 

McGill says its medical marijuana registry, which launched on Monday, is the first research database of its kind in the world. 

The registry meets a requirement of Quebec's college of physicians, which considers cannabis an experimental therapy. Under provincial regulation, cannabis can only be prescribed as part of a formal study.

It may be the best guarded greenhouse in Minnesota.

The Minnesota Medical Solutions operation in Otsego, about 40 minutes northwest of downtown Minneapolis, is growing marijuana — legally. One of two manufacturers picked by the state to produce medical cannabis, the company is readying for July 1, when it will be legal to sell the product in pill or oil form.

Security, though, is at a premium. The federal government still considers marijuana growing illegal. As officials walked reporters through the plant on Tuesday, they left no doubt they’re serious about keeping the operation safe.

For nine months, the city of San Jose has attempted to close down San Jose Organics, a major medical marijuana dispensary with over 5,000 members.

San Jose has already fined the dispensary thousands of dollars and told it to cease operations. The city is adding $1,500 a day to its fines for every day it remains open. Now, the two sides are set to face of in court.

In a hidden camera investigation, the NBC Bay Area Investigative Unit saw that the dispensary appeared to be violating several city regulations on the sale of medical marijuana.
