The only degree in my mind that would help land a career in "the field" is a business degree. Oaksterdam only teaches VERY basics of growing and touch's on the business side, that's about it.
The only opportunity is opening a State licensed growing or retail facility, and the list is LONG. Not to mention the vast amount of Money that is needed to even think about setting either one up. There will be lots of "budtender" type jobs that will pay minimum and equate to a job at Mc Donalds. The real, and only, opportunity is to be an owner of a production or retail outlet.
Remember, it is STILL a felony Federally. There is ALLWAYS a chance at going to prison until MJ is rescheduled.
As far as a growing "job", it will be next to impossible to just enter "the scene".
As we all know, it ain't easy growing one lb of superior herb that will be a step above the next guy. Some of you might think that it ain't that hard, until you try to produce 100's of lb's of that same chronic. The bigger you go, the harder it gets. The opportunity to make a living off of a few lights is slowly fading away. The knowledge needed to fire up 100 light shows is hard to come by, and is something learned over time, not through any skool or forum board.
Doing what I do, I find myself more and more like a manager then a grower. I have 10 folks working for me at most anytime. If any of you own a business, you will know employees are the hardest aspect of running ANY business. Man, I could go on and on.
So, as I write this, the only real chance at a career is on the Biz side. there are actually lots of choices here. From management to a Lab tech. A great choice would be Law School and becoming a Lawyer that is dedicated to MJ type business. Getting in on the emerging "lab" scene is another opportunity.
