Answer 1

Google search told me:
Cocaine: powdered milk or vitamin b powder. Sometimes the straw or dollar is coated in something so the powder sticks and doesn’t go up your nose, as this is very irritating when doing multiple takes.

Cigarettes are herbal cigarettes (and they are disgusting)

Prop swords with no edges and guns are (hopefully) loaded with blanks.
