I'm not really gonna go to deep into it but my personal feelings are a false positive would be infinitely worse.

Those drugs they give you do shit to you. I've been permanently altered from taking them when I was in my adolescence (I can remember feeling _significantly_ different pre and post drugs, and I've been off for many man years). There's a reason I'm not very keen on the "keep trying them till something sticks" approach that we take with this crap. Especially with developing individuals.
