Actually meds in drinking water are from multiple sources. It's well documented that MANY meds don't fully metabolize. These will be excreted in some form or another: Pee, Poop or Sweat. The question of which contributes MORE to the drinking water concern is likely those disposed of improperly through flushing.
That doesn't address the question of "will my pee put chemicals into a compost heap that mess up the composting".
Honestly I have no clue about
pee and Crohn's meds. SSRIs on the other hand are documented to survive in small quantites into the urine. So I guess if you want happy worms; start on some SSRIs.
Or pay me enough... I'm on two SSRIs, but not really inclined to pee in abnormal places. And I don't collect my urine... Court order I'm afraid... :-P (Just kidding ... there was no court order to stop...)
Diagnoses? Crohn's in 1983; Kidney Stones in 1997; Reactive Airway Syndrome in 2002; Major Depression and GAD in 2003; Migraines in 2006; ADHD and IBS in 2007.
Current Meds? 6MP; Adderall; Wellbutrin; Zoloft; Albuterol (emergencies only); Fexofenadine; and Epidrin or Imitrex (depends on migraine severity...etc)
Overall: Things are So-So. In other words "It could be worse. It could be raining."
