Black outs.

I have been smoking the same 4 strains for about 3 months now and I latley I have noticed That I am Having Black outs when I exhale the bong smoke.
(its the same kinda Buzz when you stand up to fast)..

I have been smoking it for ages and its only started happening latley...
does anyone else get this.? :confused:
and is there an explenation for it.?

Never happened to me, but I do often get some blackouts. Its just the thc fuckin wit ya mind, I'd expect.

Ya, I have minor blackouts now and then, I kinda like 'em. :D

I think it's because of lack of oxygen. You get used to the smoke so you take bigger hits and your body gets less O2

...just a theory though
