Powder to the People

Powder to the People is an unmarked quest in Fallout: New Vegas.

Detailed walkthrough
When talking to Siri, a female slave working for Caesar's Legion at The Fort, she will tell the Courier about her tough life as well as her healing powder.

With a Legion reputation of good or better, the player character can get it from her. Additionally, with a minimum Survival skill of 20, she can be told how to improve the recipe she is currently using.

The player character can then return to her once a day to get some free healing powder. If she has been given the better recipe, she will give the player character six healing powders.
