Athsat

Athsat is a potent and deadly poison, which acts quite quickly, causing difficulty in breathing, violent convulsions, and finally, err, death. Unusually, it is harmless unless activated by the victim’s own physical excitement – likely responding to hormonal triggers.

A rare and highly expensive poison, it originates in Nyissa, and is rarely sold to foreigners – and only then at prices that make its regular one seem cheap in comparison.

Caskan Wolf Snake Venom

Caskan Wolf Snake Venom is a deadly poison to various species on the planet Caska. It is also, curiously, a strong hallucinigen to humans are some other sentients.

As an illegal substance under imperial rule, Caskan Wolf Snake Venom is sometimes smuggled into the Empire’s jurisdiction.

Communion (Dark Heavens)

Communion is a deeply sinister drug, and all the more so for being legal. In a future of ecological catastrophe and over-population, that government has sanctioned mass suicides. They even provide the drug for them, at no charge: Communion.

The drug has two parts: a neurotoxin absorbed through your saliva, and a muscle relaxant that kicks in more slowly, killing you softly and painlessly.

Unless, of course, your mouth is dry from the excitement of your impending end, in which case the neurotoxin won’t work as advertised but the muscle relaxant will, killing you, but only after a minute or so of extreme physical anguish during which time you are fully conscious but unable to move.

Doxycide

Doxycide is a powerful black potion with a foul odour, which, when sprayed on Doxies, causes them to fall into a state of paralysis for a time.

The name of Doxycide is misleading, as it does not directly kill Doxies. It does, however, leave them in a state that frequently leads to their deaths.

Garrotting Gas

Garrotting Gas is a colourless vapor arising from a potion. It is unclear whether the gas is dangerous to breathe, but it can be deadly nonetheless.

The gas lives up to its name, actually strangling those who pass through it, causing choking and even complete suffocation if exposure goes on long enough.

Iocane

Iocane is one of the deadliest known poisons. It is usually found in a powdered form, and dissolves instantly in most liquids. It has no taste or smell, and is thus close to undetectable. It is also a very swift acting poison, killing in less than a minute.

Despite its deadliness, it is possible, by repeated application of the smallest doses, gradually increasing in size over a course of several years, to develop an immunity to it, although the limits of this immunity have rarely been tested, as only a single individual is known to have developed it.

Iocane originates in Australia, where it is a small but highly valuable part of that nation’s export trade, and a well-known tool of business in its criminal underworld.

Poudre de la Mort Vraie

Both a drug and a poison, Poudre de la Mort VraieThe Powder of True Death or Powder of the True Death, depending on your translator – is specifically designed for use by vampires. Created by Signalman Reynolds, formely of His Majesty’s British Army, it is extremely potent and addictive to vampires.

Reynolds, whose own wife had been a vampire, spent decades discovering how to create a substance that vampires would be attracted to. The actual formula for the creation of the grey powder is unknown, although it includes the dust of ground up mummies and assorted alchemical treatments.

Its effect on vampires is exactly what Reynolds intended: it has a euphoric rush, but leaves the vampire overwhlemed with the guilt of all their actions (both as a human and as a vampire) and not at all hungry for blood. The idea is that the vampire will be tortured by both remorse and starvation as they slowly wither away to nothing – the taste of blood will lead a vampire who has consumed Poudre de la Mort Vraie retch and vomit.

A large enough dose of the untainted blood of another vampire will throw off the effects of the drug, and a small enough dose can be outlasted – after a few days, normal vampiric instincts will reassert themselves.

Printimpolivre-bioxene

Printimpolivre-bioxene is both an hallucinogen and a paranoic. A reasonably well known compound to medical science (at least, in 2085), it is particularly effective against the alien Shorshian race.

It is often used as a poison. People who have been dosed with it can sometimes be detected by the sickly sweet odour it emits in their perspiration, by medical analysis of their bloodstream, and of course, because they’ve suddenly started seeing things that aren’t there and not trusting anyone.

Saarix

A deadly poison, Saarix-5 is a nerve gas. It is quick acting, but also fairly quick to disperse, as it oxidises on exposure to the air. It is almost universally deadly to all species exposed to it, including humans, Bellidos, Cimmaheen, Juriani and Halkas.

Saarix-5 is also able to be stored as an inert solid, in which form it is fairly safe, and can safely be handled with bare skin. Such forms are often used to smuggle the gas through checkpoints, usually with some sort of quick detonation device attached to allow its use.

Smilex

Perhaps more indicative of the insanity of the Joker than anything else about him, Smilex is a deadly poison that causes horrific facial deformations, usually in form of a rictus grin.

Smilex is made in both liquid and gaseous forms – the gas resembles a green smoke. The liquid can be mixed into almost any foodstuffs.

The puzzling thing about Smilex is the business plan behind its distribution. The Joker gives it away, seeking the widest possible range of people in Gotham, with the intent of killing them. Surely, this is insanity by any modern standard: the total absence of anything even resembling a profit motive – in fact, the Joker probably took a loss on the deal.

Weedosoros

Weedosoros is a magical poison, taught a Hogwarts School of Witchcraft and Wizardry. Little is known about it, other than that it was one of the many potions used by Severus Snape.
