Really sorry to hear about your situation stroker, hope you the best.
I do not agree on the six month thing though regardless if it is weed or tobacco or whatever.
This country needs to learn how take care of its people and not where the next fucking drop of oil is going to come from
Their motivations here are monetary yes but its but not with the same sort of ideals.... And drug tests as well as family history criminal background checks etc are standard. Think about it. Why give a heart to someone with a drug problem when there could be a "better" recipient..
I'm not even siding one way or the other. That's the view point . whether based in archaic medicince (cannabis) or not.
As far as cannabis and your heart. I would definitely recommend you abstain.
People I've monitored usually climb about 30bpm within the first hour of smoking then go back to baseline at roughly 1:30-1:45 then drop up to 10bpm at around 2:30
Your blood pressure is altered and brain excited
This bi-phasic nature of cannabis causes most of the problems regarding legitimate medical use.
In most people this isn't cause for serious comcern.. Orthostatic hypotension(light headed or fainting upon standing) and other similar problems are common however ..
But In people like yourself............
I know I know. You've been smoking it though and nothing's happened.
