I smoked a bunch of that shit when it was popular. I had my captains licence at the time and was taking regular drug screens. My advice... stay away from it. My brain has never seemed to work as well after 2 years of smoking related substances. They kept making certain compounds illegal and they'd have to change recipes a little so who knows what some of that shit even was. Last time I smoked it, random liqueur store brand, me and the chic I was dating fell asleep on Thursday night and woke up Sunday evening. We hadn't used any other substances. Neither of us had pissed the bed but neither of us remember getting up to piss. That shit cost me the best job I ever had. I just couldn't do it anymore. It's hard to explain. Don't smoke anything mother nature didn't produce man.
