Typical antipsychotic therapy increases cravings for cocaine and amphetamines in Psych patients

A study has found that

Discontinuation of typical antipsychotic therapy reduced craving for cocaine and amphetamines in patients with psychiatric illness,

but did not change drug use or psychiatric symptoms. Link goes to a review of the study.

So can we conclude the opposite, that typical antipsychotic therapy increases cravings for cocaine and amphetamines in Psych patients? Sound reasonable to me.
