I've never done any drugs that were illegal at the time of consumption. The state of nj says weed is legal, so who am I to argue, I'm not the overarching government!
Extacy and LSD are a surprisingly good combo, especially for a well supervised nature hike. You need about 1 babysitter for every 3-4 tripping people, but they can smoke weed to help pass the time. Don't drink. The tripping people will inevitably want some, and those two drugs frequently don't play nice with alcohol.
