1976: Chile's intelligence service, DINA, assigns biochemist Eugenio Berríos to develop sarin gas within its program Proyecto Andrea, to be used as a weapon against its opponents. One of DINA's goals was to package it in spray cans for easy use, which, according to testimony by former DINA agent Michael Townley, was one of the planned procedures in the 1976 assassination of Letelier. Berríos later testified that it was used in a number of assassinations.

By using Pepper Spray as a base and modifying it to resemble Neurotoxin -- i.e. using Neurotoxin's stats in AmmoTypes.XML in place of Pepper Spray's stats. I've created the necessary parts in items.XML, Weapons.XML, AmmoTypes.XML, AmmoStrings.XML, & Magazines.XML. However, in-game the Sarin Spray does not have the effect of Neurotoxin . . . what am I missing?

#define AMMO_NEUROTOXIN			0x00000001	//1			// this ammo adds the cyanide drug effect to its target, killing it in a few turns

// Flugente: ammo can now add the lifedamage drug effect. This will kill the target in a few turns.
// this is intended to work on darts, but it is possible on any ammo
if ( AmmoTypes[ubAmmoType].ammoflag & AMMO_NEUROTOXIN )
{			
	pTarget->usSoldierFlagMask |= SOLDIER_DRUGGED;

	// Add lifedamage effects
	pTarget->AddDrugValues( DRUG_TYPE_LIFEDAMAGE, Drug[DRUG_TYPE_LIFEDAMAGE].ubDrugEffect, Drug[DRUG_TYPE_LIFEDAMAGE].ubDrugTravelRate, Drug[DRUG_TYPE_LIFEDAMAGE].ubDrugSideEffect );
}

According to the code, any ammo with <ammoflag>1</ammoflag> tag adds lifedamage drug to the target:
