The first and only time I have taken weed was in Venice at a Dave Gilmour Concert in the summer - one of the best times of swim's life. sat on a high fence in the warm evening with these two aging fellas (think old acid casualty) who spoke on english (and swim speaks on italian). Swim informed me he smoked a single joint with them. On the way back to the hostel, he grew increasingly paranoid. Seeing "orange lightning" in the distance illuminating the entire night sky and then in the hostel hearing every squeak from every bed a thousand times louder echoing around until they came a single roar... Can weed do this? He didnt smoke much and didnt feel any other effects (high etc) other than the extremely vivid hallucinations and the paranoia. Would it have been laced? If so any ideas what with? Thanks for any info.
