Growing up I heard that expression often - 'she needs to get off her high horse!' I never quite got it - although as I got older I understood it - it was not till recently that it gave me a giggle. Of course when I heard it just last week this was the first thing to come to mind.
I AM a Cannabis cartoonist ;-) AND proud of it.
I do get offended if someone asks if Storm 'high' - if he was taking prescribed pills would you ask me -is he high? He is medicated. He takes his medicine to keep his chronic pain under control. 
My Country says Cannabis is a legal medicine proven to help many ailments, my Dr. prescribed it (he is a medical professional with a degree) So really - why should we care what the average  uneducated (I mean on the topic of Medical Cannabis -not on life in general ;-)  person thinks? 
I saw a post where someone said "how do you get past the opinions of others?"  It comes so clearly to me the answer. SEE that your child is no longer suffering. See that your child gets a quality of life back that they did not have before. See your child be able to sleep finally. See your child happy and have POSITIVE outlook on life with a serious illness and it no longer matters what anyone thinks. Their 'Opinion' is no longer valid.
So get off your high horse and accept it for what it is. 
A medicine - easing suffering all OVER the world for all kinds of reasons.
A Plant.     How many are we?
