Comment: Big Pharma lobbies heavily against cannabis.  Why?  Because they can't 'patent' it and make billions in windfall profits.
So they promote their semi-synthetic opioids for chronic and temporary pain through their sales-agents = Doctors, getting normal people addicted to them.  In spite of the terrible side-effects, that they are the most addictive compounds in existence and that they are lethal.  Its all about money.
