How much marijuana do you have to smoke to pass out?

There are so many different thing that can contribute to passing out while smoking.

1. Tolerance level

2. Lack (or over abundance) of sleep

3. THC content

4. Food ingested

And, some people just pass out when the smoke...it's just how they react to it. There's no specific amount of weed that one can smoke to make them pass out. But, the best way to know is to find out for yourself :)
