I think that drug mixed in coffee have same efficiency as cyanide mixed with sugar. That or shady drug won't do a shit to Renko.
Some time ago I visited sex-shop for shits and giggles and I've got some info on the topic. The shop assitant said that if there's need to cancel the effect of "ladies" aphrodisiac in between intaking and after "kicking in" without waiting to wear off - she have to drink something hot and "stimulating" e.g. potent enough coffee or tea (pref. black). So Merry in here already failed before she attempted. Looks like Jetto doing his/her research.
