Yes, only examples will show true power of this plant.
About example of doctor which apologize because he was wrong. He is exception in doctor profession. Many of them are recommending cannabis in quite to patients because curing disease with cannabis is going against official narrative and they will loose job if they openly start give cannabis to patients.
LinkRead this story from @lastdaysoutlaw about doctor who cured his wife with cannabis, but later don't want to admit it. It's from my friend:
Nothing will change without examples, no matter is subject cannabis or something else.
Doctors are afraid to loose their job(money to be precise).
