CJ's response to sandstorms

This script will add a Rockstar omission.
Now, during a sandstorm, CJ begins to choke, cough and slowly lose health.

To protect against sand dust, you can:
1) Stay home
2) Sitting in the car *
3) Wear a face mask

* Cars with a sealed interior are protected from sand. Buggy, convertibles, tractors, etc. won't save you from dust.
