the grower is licensed or not, pot is still a risky business in states that have approved its use for medicinal purposes.
Take California. While the state has had medical marijuana dispensaries for more than 15 years, it remains a target for federal law enforcement officials, where the U.S. Drug Enforcement Administration arrested nearly 8,500 people for marijuana-related offenses between 2004 and 2010.

than two years after New Jersey approved a measure to legalize marijuana for chronically ill patients, the program may finally be on the verge of rolling out.
