ScubaCollin:LoL I wasnt saying if you smoke it before you dive, thats just plain stupid. I was asking in the long run. Plus Ive done it a few times(rarely). My dive buddie does all the time and im curious if it may affect him.
Firstly it's obvious that the long term health effects of smoking anything will eventually catch up to you and affect your diving.
Second observation is that drugs and diving do no mix. It's one or the other. If you are "clean" when you dive then I don't see why can't blow now and then.
The snake in the grass is flash backs. Pot get stored in your fat and if you're hungry and diving it could come out when you least expect it, expecially if you blow a lot you need to consider this. In other words you need to know what pot does under pressure (will you get a normal flashback or will it be a doozie....) and that's a good question for the medical forum.
