Secondhand Smoke

We have demonstrated that secondhand smoke from marijuana impairs vascular endothelial function in rats, an effect also caused by secondhand smoke from tobacco, but the marijuana effect appears to last longer.  This occurs even if the smoke is from marijuana lacking cannabinoids, indicating that the effect is caused by the smoke itself and not the cannabinoids. Therefore, we are exploring whether or not this effect can be avoided by use of loose leaf vaporizers, which heat marijuana to below combustion temperatures.
