From the article
State rules provide that patients may not smoke medical marijuana in a school bus, on public transportation, in a private vehicle in operation. Patients also cannot smoke on school grounds, at any correctional facility, in a public park, on the beach, at a recreation center, or at any other place where smoking is prohibited.
All Atlantic City casinos, however, allow smoking. Revel initially opened as a smoke-free casino but later changed its stance. Casinos may designate up to 25 percent of the casino floor for smoking.
So it's not that simple.
