Action on the measure came on the same day lawmakers also approved a bill that would legalize recreational pot for adults 21 and older.
The measure was named "Jake's Law" after Jake Honig of Howell, a 7-year-old boy who died from brain cancer in January. Jake was helped by cannabis oil but his parents were forced to use it sparingly because of the state's strict limits on how much could be purchased. Those limits would be eased in the new measure.
Since March, when Gov. Phil Murphy expanded the list of qualifying medical conditions and reduced the cost of patient registration, enrollment has doubled, from 18,500 patients to 37,500, according to the state health department.
