Pain contracts

I have recently been transferred to a pain clinic to get my opioids. In order to relieve the pain I suffer with daily, I have had to give up the one pain reliever that works. I now can only use the pills they give me, not the plant that grows naturally & does far less to damage my body than the pills do. Why is it in our current society, doctors are forced to protect themselves as opposed to helping the patients. Every doctor I discuss my issues with agrees that if it wasn't for the government, I would be allowed to treat myself with marijuana rather than harmful & potentially deadly pills. I want to know where the justification is in the minds of these 'men', who decide what we can & can not do to our own bodies. Why is it that in one state you can do things, yet in another you'll be arrested? What has happened to the country that I was taught to believe in? I just want to raise my children in a world where freedoms are allowed, and given freely, not just for those in power or with money.
