The holding hits debate has been ongoing for quite some time with both sides producing evidence in their support.

As erb is very hard to find in my area, I would prefer to conserve as much as possible and have read certain NORML studies that say "as much as 40% of available THC is often exhaled."

We all know smoke is harmful and should not be held in the lungs.

However, vaporizers are much healthier on the lungs.

Oxygen deprivation killing brain cells hardly sounds like a logical argument, as one would only be holding the hit a maximum of 30-45 seconds.

Competitive swimmers hold their breath underwater for upwards of a minute, 1.5 minutes at time, while simultaneously exerting more energy and oxygen through swimming and they show no signs of brain damage, thus leading me to doubt that 30 seconds of quietly holding one's breath while not burning much energy (i.e. sitting on couch etc) contributes to brain damage from O2 deprivation.

Does anyone know of any negative consequences of holding in vapor hits?
