I would guess that some of the medical problems being mentioned (especially heart rate and blood pressure) might be related to SMOKING weed. I've never heard any reports along these lines about edibles, particularly if they're low dose. And if you buy them in a reputable store - not from a rando dealer.
For those of you who love Woody's Berliner Jazztage album, I hope you grabbed Mosaic's "Woody Shaw: The Complete Muse Sessions" box before it sold out.
