Could do that... or you could go with the non-FX
option of using a poison in aerosol form and treat it
like a tear gas grenade with chloroform or knockout
gas as the catalyst.
From the MSRD:
Tear Gas Grenade
Military and police forces use these weapons to
disperse crowds and smoke out hostage takers. On the
round that it is thrown, a tear gas grenade fills a
5-foot radius with a cloud of irritant that causes
eyes to fill with tears. On the following round, it
fills a 10-foot radius, and on the third round it
fills a 15-foot radius. It disperses after 10 rounds,
though a moderate wind (11+ mph) disperses the smoke
in 4 rounds and a strong wind (21+ mph) disperses it
in 1 round.
A character caught in a cloud of tear gas must make a
Fortitude save (DC 15) or be nauseated. This effect
lasts as long as the character is in the cloud and for
1d6 rounds after he or she leaves the cloud. Those who
succeed at their saves but remain in the cloud must
continue to save each round. A gas mask renders the
target immune to the effects. A wet cloth held over
the eyes, nose, and mouth provides a +2 bonus on the
And instead of tear gas:
Poisonous Substances: Solid poisons are usually
ingested. Liquid poisons are most effective when
injected directly into the bloodstream. Gaseous
poisons must be inhaled to be effective. The table
below summarizes the characteristics of various
Save DC: The Difficulty Class of the Fortitude save to
negate the effects of the poison.
Initial Damage: The damage a character takes
immediately upon failing his or her Fortitude save.
Secondary Damage: The damage a character takes after 1
minute of exposure to the poison if the character
fails a second saving throw. Ability score damage is
temporary, unless marked with an asterisk, in which
case the damage is permanent ability drain.
Unconsciousness lasts for 1d3 hours, and paralysis
lasts 2d6 minutes.
Purchase DC: The DC for the Wealth check necessary to
obtain the raw materials to craft the poison, or to
purchase one bottle of solid or liquid poison or one
high-pressure cylinder of gaseous poison. A bottle
holds four doses, while a cylinder holds enough gas to
fill a 10-foot-radius area.
Restriction: The restriction rating for the poison, if
any, and the appropriate black market purchase DC
modifier. Remember to apply this modifier to the
purchase DC when making a Wealth check to acquire the
poison on the black market.
Craft DC: The DC of the Craft check to create a
quantity of the poison.
Time: The amount of time required for the Craft check.
If the Craft check succeeds, the final product is a
synthesized solid or liquid poison stored in a bottle
(containing 4 doses) or a gas stored in a pressurized
cylinder. When released, the gas is sufficient to fill
a 10-foot-radius area and takes 1 round to fill the

1 Chloroform gives off vapor that causes
unconsciousness. Applying chloroform to an unwilling
subject requires a successful grapple check and pin.
