I don't know either -- the whole confused article seems like a bit part from a Cheech & Chong movie. The indecisiveness of the language suggests the authors are the ones abusing drugs.
I think they will eventually find (if they can remember what they started the study for) that the kind of people addicted to opioids are the same people that took up recreational cannabis use. They just transition from one to the other, most often from cannabis to opioids.
haha, your right, it is a stupid report. The problem is that it will be used and reported as factual “news”.
In my opinion the Opium Wars are alive and well, except this time the Chinese are us.
History certainly does repeat itself.
The Story of Opium
http://opioids.com/narcotic-drugs/chapter-2.html
“But in 1834, the old Emperor Tao-kwang, himself a reclaimed opium-smoker, determined if possible to save his country. He first of all took the sense of the people through his high officials, Shall we legalize and tax the trade, or shall we annihilate it?”
