    Is it addictive?

    It is not considered an addictive drug like cocaine, heroin or alcohol because it does not produce the same compulsive drug-seeking behavior. However, like addictive drugs, chloral hydrate produces greater tolerance in some users who take the drug repeatedly. These users must take higher doses to achieve the same results as they have had in the past. This could be an extremely dangerous practice because of the unpredictability of the drug effect on an individual.
