im a very high anxiety person and my life before weed sucked, my house was spot less, and i worked like 15 hours a day because i was always worried about everything going the way it should i couldnt be in a relationship cause they stressed me out cause you can never 100% no another persons intentions, at 21 i started smokeing pot and to quote kat williams got some of that chemical called FUCK IT! in my system and im sooooo much happier now i couldnt even maintain a relationship before cause i was always stressed. my life is still going well, my house could be cleaner but i still live my life go to work, pay my bills, my on and off relationship of 3 years has stabilized and gone from something that caused anxiety to something i find stability in, and when i told my doctor who had put me on literally ever anti depression / anxiety med he looked me right in the eyes and said "GOOD if its working dont stop, this is where medical and law differs" weed isnt just for physical ailments, it treats more then they want people to believe.

I only chose none of the above as I believe the age should be "legal Age". That would be area specific because it varies.
