President Obama told young Americans to stop worrying about getting lit without getting arrested. "Young people, I understand this is important to you. But you should be thinking about climate change, the economy, jobs. War and peace. Maybe way at the bottom you should be thinking about marijuana,” he said in an interview with Vice posted on Monday. However, Obama did speak to the problems of current drug sentencing for marijuana and other currently illegal substances. “Substance abuse generally, legal and illegal substances, is a problem. Locking somebody up for 20 years is probably not the best strategy,” he said.
