Poisons are invariably detrimental to one or more species' well-being. While many drugs can induce similar effects, these may have other potentially beneficial uses whereas poisons are designed and/or administered with the primary intent to harm.

Navigable environments may incur poisons through several means, with the resulting areas being called toxic hazards.

Butanediamine Edit

Also known as putrescine, this compound is one of the byproducts of organic decomposition.

Cerberus turian poison Edit

Cerberus developed a neurotoxin tailored to turians that saw usage during their failed takeover of the Citadel. General Korilius was stabbed with a poisoned blade while defending civilians, rendering him comatose with the doctors at Huerta Memorial Hospital unable to identify the toxin.

Schematics for the poison can be found at an ex-Cerberus facility on Gellix. A former Alliance researcher has data on a similar toxin that was developed in case of a war with Palaven, and is amenable to selling it at the Spectre Requisitions office if the Cerberus schematics weren't taken from Gellix. Either can be used in the synthesis of an antidote that cures General Korilius.

Drell subcutaneous oils Edit

The drell secrete a toxic compound that other species find highly intoxicating and even hallucinogenic. This is why they generally do not wear environmental suits; even they would suffer its effects after prolonged exposure.

Element zero Edit

Main article: Element zero

Exposure to significant amounts of eezo either grants biotic ability to the victim (and offspring, if pregnant) or promotes the growth of cancerous tumors. Overexposure tends to shift the balance to the latter.

Final Jest Edit

A batarian poison that turns blood to lighter fluid and uses the brain's electrochemical pain response to set the victim on fire from the inside. Victims end up with big fat orange blisters that may be blue if the venom sacs aren't too fresh, but the observations are moot since they explode quickly anyway. Available on Khar'shan.

Fusion containment cell Edit

Commonly found throughout mercenary bases and unsafe starships, these items emit clouds of poison gas when violently destroyed. The gas dissipates after a while.

Mother's Milk Edit

A caustic liquid that dissolves the victim's throat mid-swallow. Gives victims a suppurating "scarf" of red. Another batarian poison available on Khar'shan.

Pauper's Pleasure Edit

A batarian poison available on Khar'shan. Pauper's Pleasure causes purple hives in the victim's skin before their saliva boils and they slowly braise in their own bodily fluids.

Pentamethylenediamine Edit

Also known as cadaverine, this compound is one of the byproducts of organic decomposition.

Polonium Edit

This element's radioactivity is used to coat certain types of ammunition for extra damage against organic targets.

Ruthenium dichloride Edit

This compound is most often used together in commercial canning, preserving, bottling, and labeling, though it is toxic to asari, humans, and salarians. It can be found in Horosk bottles.

Sulfur Edit

The prevalence of sulfur and its compounds in Kadara's water supply renders the planet hostile to colonization. Filtering them out is required before the water is deemed potable.

Thoros-B Edit

Main article: Thoros-B

Thoros-B is a toxin developed by Binary Helix as a multispecies bioweapon.
