BZ Gas

The BZ Gas is a special weapon featured in Grand Theft Auto V.

Description
It is essentially a non-lethal version of the Tear Gas. The BZ Gas is a knockout gas developed by the Humane Labs and Research, likely for military use.

The BZ Gas only appears if the player has chosen the smart approach for The Jewel Store Job. It first appears in the BZ Gas Grenades mission where Michael must steal them from a Humane Labs Boxville. Later, they appear in Franklin's inventory during the heist. The player must throw one in the vent in order to allow Michael and the heist crew to safely rob the Vangelico store. They are not seen afterwards.

It is possible to spawn them through a trainer, although they will simply behave like regular Tear Gas grenades.

Trivia

 * BZ is the real life code for a incapacitating chemical weapon developed in the United States in the 1980s. Much like the in-game BZ Gas, it is non-lethal.
