Well, that's what movies do. They make everything extreme for entertainment purposes. It's how the killer always catches up to the victims, or the guy who nearly died can come save the day at the end of the movie, or how a family can win a dead mans keno when they've run out of money on a casino vacation.
Besides, I'd rather the effects of weed be extreme in movies. I'm not paying to watch a guy sit in a room smoking a bong with Bob Marley posters, candy and pizza while playing COD. I can hangout with my boring friends and watch that.
