I think this synopsis is very well-written. It pulls the reader in immediately and introduces the story without giving too much away.
In the first paragraph, I'd change every "where" to "when" because you're talking about times, not places. Also, the paragraph about the survivors sounds a little awkward to me. I'd probably edit it like this: Well, they live in the wastelands that the great war has left behind. They live where nothing is safe and where* drug lords rule with an iron fist.
* I was also considering writing this: They live where nothing is safe from the drug lords that rule with an iron fist. However, I wasn't sure if the drug lords were the only reason the wastelands weren't safe.
To be honest, your synopsis is really great, which is why I nitpicked so much. I'm looking forward to reading the rest. :)
