This study found that ritalin use leads to cocaine abuse.

Stimulant treatment in high school also did not influence drug use in
adulthood except for greater use of cocaine.

They found, unfortunately, that treatment with stimulant medication in
high
school is significantly associated with the risk of ever trying cocaine.
That this is a valid conclusion is supported by their finding that
treatment
with stimulant medication in childhood is associated with cocaine use in
adulthood, although after adjusting for "disease severity" and the
presence
of conduct disorder, the association was no longer significant.
The authors work extraordinarily hard to explain to the reader why the
first
finding, which is statistically significant, is actually not real. The
naïve
reader may wonder why the authors are so invested in undermining their own
carefully performed results.

It is not hard to explain. The study author is a big promoter of stimulant
medication
for ADHD, and has written a book on the subject.

See last sentence....(roger, the last sentence is the one with the *** in
front and in back).

Results. Duration of stimulant treatment was not significantly associated
with frequency of any form of drug use by young adulthood. Stimulant-treated
children had no greater risk of ever trying drugs by adolescence or any
significantly greater frequency of drug use by young adulthood. Stimulant
treatment in high school also did not influence drug use in adulthood except
for greater use of cocaine. This difference was no longer significant after
controlling for severity of attention-deficit/hyperactivity disorder and
conduct disorder in childhood, adolescence, and adulthood. Stimulant
treatment in either childhood or high school was not associated with any
greater risk for any formal Diagnostic and Statistical Manual of Mental
Disorders, Third Edition, Revised drug dependence or abuse disorders by
adulthood. Treatment with stimulants did not increase the risk of ever
having tried most illegal substances by adulthood except for cocaine.
***Subsequent analyses showed that this elevated risk was primarily mediated
by severity of conduct disorder by young adulthood and not by stimulant
treatment in childhood.***

Can you read? Did you understand that sentence if you could?
