I mean, would it be all right in terms of safety? My dad was curious on how weed is so I said i'd get some for him. He has elevated blood pressure and he takes meds for it, like beta-blockers I think, on a daily basis now for years. He can drink coffee just fine and he smokes from time to time (cigarettes) and all that, but would it be okay for him to try a few puffs? Worst case is I don't want him freaking out over the increased heart rate and panicking.
