Synergine

Synergine is a legal drug throughout the Galactic Nexus, where it is used as a combination of stimulant and painkiller.

It is particularly useful for shaking off the after-effects of stun rays (it will not revive them, however), and also as a treatment for those recently revived from cryosleep. It operates largely by assisting the body’s natural healing processes, accelerating and increasing their effects.

Synergine is particularly effective against headache symptoms, shock and most forms of nausea; it is, however, completely ineffective against the nausea caused by spacesickness.

Fast-Penta

An almost completely reliable truth serum, Fast-penta is a commonly-used tool of ImpSec, the Barrayaran intelligence agency, and of numerous of its allies and enemies, too.

The drug itself relaxes physical tensions, as well as mental and emotional inhibitions. It is not so much that it compels honesty, as that it compels docility and helpfulness – which, in the hands of a skilled interrogator, amounts to about the same thing.

Artificial immunity to it is sometimes given to operatives by their agencies, and more rarely, some people have naturally idiosyncratic reactions to it, in which the effects are more similar to those of ecstasy or LSD – Miles Naismith Vorkosigan is one of these.
