Several UCD Students have been hospitalised after taking a bad batch of drugs.
Students are being warned not to take the potentially dangerous substance.
Several students were taken to hospital on Tuesday night after taking the new drug cocktail known as scuzz.
They are believed to be in a stable condition after using what's thought to be a combination of LSD, speed and other amphetamines.
Gardai have launched an investigation and asked the college to issue a warning to students.
UCD's student union has taken to twitter and facebook to highlight the potential dangers of the drug.
It also says that gardai are worried that fatalities could occur if the batch is not taken out of circulation.
