'Neutral Red' is sold in pet stores to give to pets, so you know where(if) they are peeing. It's supposed to be safe to ingest- but don't take my word for it. Check the bottle.
Edit: It will stain skin, and it comes out the same color- eg red pee. It'll make them think they're pissing blood.
Same suggestion for me.
Laxatives are a no-no. Under the worst case scenario - someone decides to press charges - you're on pretty shaky ground...
"And, why did you lace your drink with laxatives?"
"Because I wanted to find out who was drinking my beverages."
"Ahh, so you assumed someone else was going to drink it?"
"Yes, that's correct."
"So, you're admitting to intentionally tampering with a product that you knew someone else was going to consume."
= felony (IIRC)
