Hello from AZ, a intro for a true first timer

Well, honestly i have had back pain and depression for a long time my depression was once so bad that i simply could not do anything except stay in my house and venture out from time to time to drive someone somewhere.

But through therapy and time its gotten better, however i literally have to fight it everyday. Its a struggle just to get out of my bed sometimes. Having back pain doesn't help a lot either, I am only 19 and sometimes I can barley move, it makes me feel older than my parents since they can do so much without worrying about the pain involved, or spasms for that matter.

Only a few months ago i had to go to the E.R. because of that pain, it simply wouldn't go away and I was having spasm attackers left and right, they put me on demerol and the pain went away but they had to use a lot (I didn't feel high at all, weird but true).

Anyways Arizona has legalized Cannabis (albeit only just) and I don't want this pain anymore, and I heard it can do a lot in the ways of relieving anxiety, stress, and depression. However I have never done more than take a few ibuprofen more than what it says to take. So I have never had alcohol, cannabis, tobacco or any other mood/mind altering substances besides demerol that one time in the E.R.

My question is simple how does a guy with no money, anxitey/depression(i know not the same thing but it swings from me being in the house to being outside), and absolutely no knowledge of how to not only smoke the weed, but how to get it?

I want to use Cannabis for the first time for back pain, depression, and anxiety. I have no money and I have no idea even where to look
