The national drug overdose epidemic has been steadily on the rise for nearly 20 years. From 1999 to 2010, deaths surged a colossal 102 percent. And while overdoses kill more people each year than either cars or guns, the debate over what can be done to address the disturbing trend often gets overshadowed by noisier killers.

CNN's chief medical correspondent Dr. Sanjay Gupta apologized Wednesday for publicly opposing marijuana legalization, saying there was "no scientific basis" to claim marijuana had no medical benefits.

Fulfilling a campaign promise, Gov. Maggie Hassan signed a law Tuesday making New Hampshire the 19th state to allow seriously ill residents to use marijuana to treat their illnesses.

"Allowing doctors to provide relief to patients through the use of appropriately regulated and dispensed medical marijuana is the compassionate and right policy for the state of New Hampshire, and this legislation ensures that we approach this policy in the right way with measures to prevent abuse," Hassan said in a statement.

The prospect of reversing blindness has made a significant leap, according to scientists in the UK. An animal study in the journal Nature Biotechnology showed the part of the eye which actually detects light can be repaired using stem cells.

The team at Moorfields Eye Hospital and University College London say human trials are now, for the first time, a realistic prospect.

Experts described it as a "significant breakthrough" and "huge leap" forward.
