Nearly 1 in 4 Arizona teens have used a highly potent form of marijuana known as marijuana concentrate, according to a new study by Arizona State University researchers.

Among nearly 50,000 eighth, 10th and 12th graders from the 2018 Arizona Youth Survey, a biennial survey of Arizona secondary school students, one-third (33%) had tried some form of marijuana, and nearly a quarter (24%) had tried marijuana concentrate.  

Sometimes during a trial a lawyer will get angry, a witness will speak out of turn or a defendant will have an outburst. The judge will then calmly instruct the jury to disregard what just happened.

In theory, it’s supposed to keep emotion and bias out of the legal system. In reality, ASU assistant professor Jessica Salerno said, it’s hard for humans to separate thoughts and emotions so neatly.
