Yes it is still "illegal" to openly smoke marijuana but please don't get the misconception that it won't be going on. It is true that there will be officers patroling the crowds but I assure you that as long as you are discreet and respectful you will have no problem blending in with the other hundreds of smokers who partake on the rocks next to the water. It is very seldom citations are even written at this event and more often than not they involve things other than weed. Last year some people by the XIL stage were causing some trouble but as long as your cool your good to go. I believe most of the tickets are actually given to people smoking blunts while roaming the crowd. The scene up here might not be as open as Cali, there is definately just as much to offer...Have fun!!
