Smoke typically travels upwards in a closed room due to the natural tendency of hot air to rise.
In a closed room, cigarette smoke tends to rise upwards due to its heat and buoyancy.
Smoke rises in a closed room because it is less dense than the surrounding air.
Cigarette smoke rises in a closed room because it is lighter than the surrounding air.
Cold air tends to sink and move downwards in a room, while warm air rises and moves upwards.
Crawl on your hands and knees to stay below the smoke layer where the air is less toxic. Cover your mouth and nose with a cloth to protect your airways. Find the nearest exit and evacuate the room as quickly as possible.

Smoke is nothing but airborne ash, which will carry all the chemicals in the smoke throughout the room and onto surfaces-- including the food.
Something is preventing your fireplace from drawing. The damper may be closed, or partially closed. Your chimney may have a blockage, or you may have prevailing winds that push smoke back down the chimney. If you have air flow problems, such as a vent fan that draws air out of the house, it can cause that. Bottom line- if the damper is open, and the flue is not blocked, you need a good fireplace/chimney specialist to examine what you have.
Universal Studios closed down the Jaws ride on January 2nd, 2012. The ride was shut down to make room for other rides, which may include rides that are Harry Potter themed.

The smoke is attempting to reach equilibrium with the system (the closed system being the room), and as such tends to distribute itself relatively uniformly around the room.
It is unlikely to get a contact high from sitting in a room with weed smoke unless the room is poorly ventilated and you are exposed for an extended period of time with a high concentration of smoke.
Burning of coal in a closed room will have suffocating effects.
Sound can travel faster through space because space is a vacuum where there are no particles to slow down the transmission of sound waves. In a room at room temperature, sound travels through the molecules of the medium, such as air, which can slow down its speed.
