Also they would I am guessing be giving some kind of drug that is close to Ketracel White but not addictive.
Minor side note, but is the Ketracel White drug really 'addictive'? I mean, the Jem' Hadar were designed to need the drug, it's not as if one of them (as currently engineered, and without that mutation fluke we saw in Hippocratic Oath) can live without the drug, then get themselves 'addicted' and later get 'unaddicted' again. Are we humans similarly addicted to essential amino acids, for example?
