SCB Syndrome, or Swiss Cheese Brain Syndrome, is the medical condition, caused by excessive intake of such a wide variety and extensive multitude of recreational drugs, whereby the victim's brain resembles Swiss Cheese.
The depth of the syndrom is generally measured by the diameter of the average sized hole or tunnel through the brain, and ranges from very small (just slightly large enough to fit a microdot within) to medium (just large enough to fit a large marijuana seed inside), to extreme (large enough to fit 1 or more trittles inside).
