Marijuana Laws

As recorded December 15, 2025 · not verified as current law. New Jersey law

Cannabis laws in Princeton follow New Jersey’s state law. The rules here are set by the broader jurisdiction, and city-level differences are uncommon.

Recreational cannabis is legal for adults 21 and older. Medical cannabis is also available. Cannabis remains illegal under U.S. federal law, which can create risks in federal areas or during cross-border travel. Possession and purchase are regulated.

Quick facts

  • Recreational: Legal (21+)
  • Medical: Legal
  • Possession: No strict limit (large amounts may raise issues)
  • Buying/Selling: Legal from licensed dispensaries
  • Tourists: Permitted with valid ID (21+)

Practical guidance

Avoid cross-border transport of cannabis products. Do not assume informal tolerance equals legality.

Law Enforcement

Princeton, Kingston, Plainsboro and West Windsor felt safe, but local cops had a reputation for actively looking for smokers. People worried about smoking in cars, out in public and even in a visible backyard. New Jersey has since introduced regulated adult use, as covered in Marijuana Laws.

Where to Buy Marijuana

The area had little street activity and strangers tended to keep to themselves. House parties at Princeton or Rider were a more likely place to meet someone with a couple of dimes. Trenton was described as about 15 minutes away by car and New Hope, Pennsylvania, about half an hour.

Marijuana Prices

  • Regs: US$25–40 per ¼ oz or US$110–150 per oz
  • Mids: US$160–200 per oz
  • Kind bud: US$20 per gram, US$90–120 per ¼ oz or US$300–400 per oz
  • Haze, when it turned up: US$25–30 per gram or US$500 or more per oz

Types of Marijuana

Regs, mids and kind bud were the usual grades. Haze was the rare, expensive option.

More Information

People worried about criminal charges even for a joint. The expectation at the time was that a good attorney might keep an under-50 g case from ending in jail, but the fees and fines could still add up. Carrying it in a car was considered risky, and smoking in the car more so.
