According to the State of Oregon, Marijuana is a medicine!!

So, I was thinking.
According to the State of Oregon, Marijuana is a medicine. It's "medical" marijuana with "medicine" dispensaries.
So, is a person who dispenses "medicine" at these "state licensed" locations required to be a licensed pharmacist?
What if a person is taking other prescription drugs that are not compatible with marijuana? Does the person at the dispensary inquire if the person is currently taking any narcotics or other prescription drugs?
Is the dispensary person behind the counter educated enough to know there won't be any adverse or potentially deadly reactions to say a drug prescribed for liver disease or a blood thinner etc?
If someone does die from "mixing" deadly drugs who gets sued?
The dispensary?
The State of Oregon?
The doctor who prescribed the marijuana?
These dispensaries are in fact acting in the same capacity as a pharmacist with absolutely NO understanding or formal training necessary to identify or avoid any potential drug interactions.
Just thinking.
Let's push this one to the "liability" front burner. Thank You Ken Perkins!
