How monitored are stoner movies with their stunt weed?

Fair enough. I suppose if, for stoner movies, they wanted to actually get high as a sort of method acting, they could smoke in their trailer before they walk on the set. I read somewhere that that's what Rogen did with Kevin Smith in Zack & Miri Make a Porno.

I didn't see that film, and there is no way of knowing unless the actors or filmmakers said something in an interview.

But I've worked in the industry off & on, and my understanding is, today - for most big studio feature films, props are just props. Because today, everything is monitored & controlled, from sex scenes, props, action/stunt scenes, and mostly the budget, schedules & insurance. There are a lot of contractual, legal controls over everything in studio movies (not as much for independent films.) So I guess that means it has to be fake weed, because if it was real and they kept flubbing & slurring their lines, and spent all day filming one scene, it would go over-schedule & over-

budget. Big studios are very accountable today. Actors sign a contract & have to be on set & ready for certain days.

A long time ago Hollywood studios learned the hard way and lost millions of $$ when productions got shut down, or accidents happened, an actor got injured. Oliver Reed died during filming Gladiator & it cost over a million to

complete his scenes digitally without him. Michael Cimino lost the studio millions making Heaven's Gate & ruined his career. Marilyn Monroe showed up on drugs, messed up her lines, they had to shut a few of her movies down.

Brandon Lee was killed by a stunt gun w/ a real bullet before The Crow was done filming. They don't allow those kinds of costly mistakes to happen.
