What I have been told is that in my area the precursor to heroin addiction is usually prescription painkillers, not marijuana.
That is very much the case; often legitimately-prescribed painkillers lead to the addiction, and heroin is cheaper than the pills.
What I see in the scientific daily data.. is they are testing positive for both.. I run drug tests everyday. So.. as usual, the data doesn’t lie, but people do. The question is why? Why not provide the data. They die with more than seventy percent with both drugs.. it is the heroin od. that kills them, but they are also treating their pain with pot. The dopamine system gets wracked and it’s a domino that starts the game. Lots and lots of children in dire straits because of this. Had one set of parents who smoked all day and um never took their six year old to school. Finally, the state placed him and he is a year behind.. well much more than that, in reality.
