SWIM recently got some opium from a trusted friend, or what he thinks is opium. It is a tary, gooey, amber brown substance in foil, which caused the foil to stick to itself ridiculously. Swim heard that you have to burn it at high heat so swim used a jet flame butane lighter, it would bubble up smoke a little bit, and then after it cooled down it would be hard and crumbles in a wierd way. It really didnt give swim much of a buzz aside from the bowl of weed it was on. It was from a reputable source but swim is questioning it now. Swim smoked about four match head size bowls, not enough? Swim is not new to opiates whatsoever so swim knows what the buzz should resemble and this aint it. Is this really O?
