The kerfuffle is shedding light on one of the more obscure, and potentially lucrative, parts of the commonwealth's medical marijuana program. Under Pennsylvania's law, in addition to the dozen commercial marijuana growers, the state's eight university health systems can partner with aspiring cannabis cultivators. The health systems will not handle any part of the marijuana plants or its derivatives, but they will lend their names to the partnerships and ostensibly conduct research into the benefits of the drug.
