Ritalin: consequences of abuse in a clinical population

This study examined the use of methylphenidate (Ritalin) among clients of drug abuse treatment programs. A review of the literature suggested that serious complications are to be expected from frequent abuse of Ritalin, particularly if administered i.v. Treatment personnel have also suggested complicating factors surrounding the abuse of Ritalin during outpatient treatment for opiate dependency. A consecutive series of admissions (N = 192) was examined for their use of Ritalin, with special attention given to history of use, means of supply, and adverse consequences associated with the abuse of this substance.
