All indications are that Rush is using the medication for a valid medical condition and is suffering from the results of using that same medication.
There are several medications that are not suppported or 'approved' by the medical 'authorities' and therefore are not 'legally' or 'readily' available in the U.S. even though they are legally available elsewhere. Also, some medications are provided for by some insurance policies and not by others. Furthermore, some doctors or hospitals will prescribe some medications, but other hospitals or doctors will not prescribe those same medications.
I see nothing wrong with a person going outside of the 'system' to obtain critically necessary medications when they are not provided due to 'insurance' or other excessive restraints.
If Rush was terminally ill, he would have no problem legally obtaining the same medications that he is now having trouble obtaining due to someones believing that those same medications are harmful in the long run due to their addictive nature. It is obvious that Rush is suffering from long term pain that is not able to be relieved through surgical means and the long term usage of pain relievers is the only way to relieve said pain.
It is wrong to prohibit pain relief for someone just because the medication is addictive.
He also is not engaging in various criminal activites to obtain his needed medication.
Oh wait, then you say:
I see nothing wrong with a person going outside of the 'system' to obtain critically necessary medications when they are not provided due to 'insurance' or other excessive restraints.
That would also be known as engaging in various criminal activities to obtain needed medication.
