A visit to UC San Diego from Sir Richard Branson, founder of the Virgin Group and member of the Global Commission on Drug Policy , was bound to cause a stir. But how do you explain his late arrival to a campus event on drug use and HIV in Tijuana? His flight was on time, but his driver took him to the wrong university! No matter. Moderator Steffanie Strathdee deftly hosts a fascinating discussion with Proyecto El Cuete research director Dr. Patricia Gonzalez-Zuniga and author Jon Cohen that gets even better when Branson finally takes the stage and opens with a hilarious, off-color joke. Strathdee also previews material she will be presenting this week at the 21st International AIDS Conference in Durban, South Africa.
