one of the interesting things to me is that, smoking cannabis, especially holding in a hit, really interferes with oxygen flow to the brain. this is precisely the nature of my cardiac issue. I have right ventricular tachycardia-displaysia. (think i spelled that right) when my right ventricle fails to pump blood to the brain, that is where my risk lies. so my thoughts are, if by vaporizing, I do not disrupt oxygen intake or flow to the brain, there is not going to be the risk of inducing an arrythmia. thats my thinking for now. so, as it stands, I am going to TRY vaporizing, and if I have any problems, like an elevated heart rate at all, then I will be waiting several years until I can eat it....until then.....
