When colorado first had legalization, the only cannabis related death was from a tourist having a 6 dose cookie . He had never consumed cannabis before, and had some sort of break and jumped off the balcony of his hotel room. The dispensary did tell him to only have a sixth of the cookie to start, so yes edibles arent the smartest to start with unless its microdose like 5mg. Now the good thing with edibles that are 50/50 THC/CBD is the CBD generally reduces some of the anxiety and also counteracts some of the psychoactive effects of the THC, hence why thats the only way I would suggest to start with edibles if one is a noob.
