Cali is by far the easiest place to get a card. It's also the most difficult to get a MMJ related job since its so widely accepted and everyone wants those jobs. You're also competing with people with tons of experience there.
The more recent MMJ is to a state the easier it is to get a job since the industry is just starting out, but paradoxically the more difficult it is to get a card since most states are very very cautious to avoid getting California's reputation of handing out cards to anyone with $200 and a stubbed toe.
Basically it doesnt matter where you go though, having a legitimate medical problem that has been proven to have its symptoms alleviated by marijuana, and having a adverse reaction to traditional medicines to treat your disorder makes you a valid candidate for almost every state. Also keep in mind that just because you're medicating doesn't mean you have to have a job that doesn't drug test. Most companies only test before your initial employment, and subsequent tests only come up if it becomes an issue at the work place. As long as you aren't trying to be a brain surgeon, most employers are willing to allow you to medicate on the job provided that it doesn't impact your performance in any way and provided you have proper documentation and recommendation.
If not there are a growing number of companies out there that just outright have stopped drug testing since most "hard" drugs cycle out of your system fairly quickly and, quite frankly, most employers don't care if you smoke pot. Whole Foods is a prime example, they ceased drug testing altogether, and I'm sure you could find many employers from various fields with the same policy.
Also keep in mind that drug testing is an expensive process. Small businesses and family run operations generally do not test and there is of course always the option of starting your own business or even starting growing!
Good luck with your travels and medicating!
