my (relatively limited) experience with various forms of non-oil edibles, is they make me rather paranoid and nervous. I've gotten that nervous buzz from about six different types of edibles so far.
I can get that way with some of the activated oils, if I consume too much, but a moderate amount and I get a really nice, pleasant, confident and long-lasting buzz. I feel sure that certain cannabis strains of flowers also can make me feel paranoid, and while I cannot name them, when I find one, I stay away from it.
The OP article is only "linking" edibles with deaths. They are not saying the edibles "caused" the deaths. As with many things, more than one factor can play a role.
Goodness knows our phramaceutical industry is putting some dangerous chemicals out there and into our systems. I have had some bad experiences with pregablin (Lyrica) and gabapentin (Neurontin) recently, and if I had died (and the Neurontin made me feel like I had died), I would have had some marijuana in my system at the time. I wonder if my death would have been "linked" to cannabis?
