My question involves criminal law for the state of: New Jersey

**What Happened:**
Last night, my brother (19) was arrested for a DUI. During the arrest procedure, he told the police officers that he was suicidal. They had him go through many tests and had him to talk to a social worker. During the many tests, they discovered that he had traces of marijuana in his system. He also told them that he smokes three times a week. He has a small possession charge on his record.

After talking to the worker, he is now being shipped to a psychiatric ward because they have deemed him suicidal. He says that what he told the officers is true and that he really does want to kill himself. This scares the shit out of my mom and I. Since this is so recent, my mom and I are not sure of the implications with the law. I'm really hoping you guys can help. More importantly though, we're really worried about him.

His driving record currently has one speeding ticket. Recently, he got into an accident and was charged with reckless driving, change of lane, and failure to provide insurance. We paid a lawyer to take care of this accident on the 21st.

The current DUI related charges against him are
  • DUI
  • Speeding (83 in 55mph)
  • Reckless Driving
  • Failure to provide registration


So my question is does testing positive for marijuana will induce another charge? What is a likely outcome of this shitstorm?
