New regulations for medical and recreational marijuana businesses will go into effect today.

Renewal fees for medical marijuana licenses have decreased, and the way in which retail marijuana grow facilities are categorized has changed to be more specific; plant numbers are broken into smaller unit sizes.

Overall, it’s now more expensive to set up a dispensary that serves medical patients rather than one that sells only recreational cannabis. Initial application fees for medical centers range in cost from $6,000 to $14,000 and are separated into three tiers.

Amendment 139, a proposal that’s seeking a spot on the November ballot, is getting attention primarily for a section that would limit the potency of marijuana products to 16 percent THC — a reduction for a huge number of currently available items.

But that’s not all the measure would do. A139, which is on view below, would also put childproof-packaging regulations into the Colorado Constitution along with labeling rules that could require warnings about mood swings, impaired thinking, possible addiction and even temporary paranoia.

New Jersey state senator Nicholas Scutari takes questions at his press conference on marijuana refor

During a four-day trip to Colorado earlier this month that took him through Boulder, Golden and Denver, New Jersey senator Nicholas Scutari, a Democrat from Union, examined the effects of legalizing recreational marijuana. He concluded that similar legislation could benefit New Jersey.

His trip included visits to dispensaries and meetings with state officials, law enforcement and local business owners. In a press conference held when he returned home, he said he came away with a better understanding of safety regulations, such as making sure packaging on marijuana products indicates clear dosage levels and equipping police departments with drug-recognition experts.

Forty-three-year-old Alex Sanchez spent just one night in jail last October after he was arrested for growing weed at his house in Kendall. When he returned home, the electricity wasn’t on. Sanchez called to figure out what was up and stumbled upon a little-known county ordinance that prevented him from taking a hot shower or cooking himself dinner unless he forked over what amounted to his life savings.

That day, Sanchez learned he was on the hook for thousands of dollars in fees, inspection costs, permits, repairs, and, eventually, once all of that was paid off and completed, a four-figure deposit payable to Florida Power & Light.
