So, it was mentioned by the devs that they feel as though the bonus to HQ food is too small and will be improved. What about drugs? A difference of +10% for a Mega-Potion of Strength hardly seems worth it, right? Going from +40 STR to +44 won't make a big difference, so no one really has an interest in it and there is no market for it.
Also, separately, why not allow repeated use of medication? Just as in real life, over-use of medication has negative effects. If the 4-minute timer for re-use has not passed, why not force us into Weakened status? I think it would be a pretty fair and fun thing to add into the game. A third use would result in Brink of Death.
