The three were taken to James Cook University Hospital after police were called to Elton Street, Redcar, at around midnight on Saturday night.
A Cleveland Police spokeswoman said: “Anyone who has taken the drug and is concerned should seek medical advice. Those with serious side effects should seek urgent medical treatment.”
The three people remain in hospital but are no longer in a critical condition.
Three men, two 22-year-olds and a 23-year-old, were arrested on suspicion of supplying a controlled substance.
