motion of doctor's hand on generic approval form
You pay $100 (+/- $50) and you can immediately walk down to a dispensary and get whatever you want.
I've got with these guys, they have two offices in SF and an online appointment scheduler: http://green215.com
It's perhaps not that easy, but it's within delta of that.
The thing is, marijuana is thought possibly to be beneficial for a huge swath of conditions, many of which are primarily self-reported like insomnia and migraines. A normal doctor would probably not give you the third degree you before suggesting a treatment for these conditions either. And since marijuana is largely benign even when it doesn't help, this is not really irresponsible on the marijuana doctors' part. My doctor was advocating a riskier course of treatment when he told me to take ibuprofen!
If so why are some people (not all) who are supposedly "sick" trying to get low THC pot?
Although these days with very strong pot low could mean 10% THC.
If you go poking around weedmaps.com (well, after their site starts functioning again :/), and look into strain-specific details there, there absolutely are low THC strains available, and also amazingly high THC level strains. High and low CBN/CBD, etc.
In addition, they have some space dedicated to breaking out the main/known active contituents in MJ, and what they're believed best to affect.
