Possible? Yes. But without further information, it is impossible to tell what is "probable." You might want to think about, and suggest, a verifiation regimen where someone (a third party) administers and actually observes the meds being taken. Absent that, yes, you are left with only the difficult and onerous path of instituting contact restrictions, which are near-certain to meet resitance.
Without a complete knowledge of the fcts, it is nearly impossible to suggest a course of action -- what you need is a detailed consultation with a qualified family law specialist.
