But Christie suggested on a radio show Wednesday night that he may not sign the bill as it is, partially out of fears that people other than the children cleared to use it wouldn't be the only ones who do.
"I know parents are concerned about the health of their children," Christie said Wednesday on TownSquare Media. "I have to be concerned about the health of every child."
Christie said he's reviewing the bill.
He has until Aug. 8 to take action, by signing it, vetoing it or issuing a conditional veto that sends it back to lawmakers with instructions on what changes they could make that he would find acceptable.
While parents and other advocates intend to make a splash Thursday by hand-delivering their appeal, they likely won't see the governor himself. He's scheduled to be at a meeting in Nevada.
The Legislature passed the measure in June after hearing about the plight of a Scotch Plains girl with severe epilepsy whose parents had not been able to find a psychiatrist to sign a consent form to get her access to medical marijuana.
The bill would eliminate the need for written consent from a pediatrician and psychiatrist to be eligible. It also would allow legal dispensaries to produce pot in an edible form.
New Jersey adopted the law to allow medical marijuana in 2010, but since then only one dispensary has opened, and it's been closed much of the summer due to low supplies. A second operation is planning to open in September.
