- BONG! Sorry, that is not the correct answer. Thank you for
- playing, please try again.
-
- Nitrogen Narcosis can occur at depths as shallow as 70-80'.
- SYMPTOMS occur generally at depths around 120'-140'. That is,
- beyond 100' and you can have truly hazardous effects. This is,
- of course, dependant on your personal susceptability.
-
- At 300', OXYGEN TOXICITY occurs. This an ENTIRELY DIFFERENT
- problem and is MUCH more hazardous. Oxygen Toxicity happens
- suddenly and as subtly as a sledgehammer to your head. It
- causes violent convulsions and unconsciousness, and, as a result,
- death. This is not something that we are individually susceptible
- to; it's pretty uniformally deadly, at about 298'.
-
- Anybody diving to 200' and deeper is going to be SERIOUSLY narc'ed.
- Whether they feel panicky, euphoric or start hallucinating varies
- from person to person. But at 300', getting narc'ed is the LEAST
- of your worries.
-
- Had to clear that one up quick. :-)

- p.s. Please be sure about such things before posting them.
- 300' for N2 narcosis is a hazardous misconception. And, as
- much as people should always check things they read on the
- net, many people don't.
