How about the possibility of just making a decent happy living?
It's possible but get in line with the all the others dreaming of a career in the marijuana industry. This is now a business run by business savvy individuals with money. If you want to work for them expect to get paid as little as they can get away with and still find employees.
Typical jobs won't pay much more than minimum wage. If you have a significant amount of capital and wish to risk it then you can apply for all the permit and licensing fee's, rent a warehouse, buy the equipment and other supplies and try to become a grower. But then you could end up with a bunch of marijuana and nowhere to get rid of it.
There are hundreds if not thousands of licensed legal growers trying to get their product on the shelves of dispensaries. You could go the route of opening a dispensary but that takes MONEY as well.
My advice is to keep your day job if you have one. Grow your weed on the side and enjoy your life.
I've looked into this extensively at all aspects of the industry. I have plenty of money thanks to being an early adopter of bitcoin but there is no way I'm risking my money in this industry.
Here are some things that you need to think about.
If you want to be a commercial grower you need a place to grow. Land costs money and growing outdoors can be boom or bust. Growing indoors requires a location and rent. You most likely would have to sign at the minimum a year long lease. Then add the cost of equipment, electricity, etc... and you're talking tens of thousands of dollars to get started with no guarantee that you'll be able to have an outlet for your product.
Opening a dispensary also has significant upfront costs. You'll need a location and have to sign a lease, remodeling that location, cases, employee's, etc... Once you hire employee's you are now an employer and subject to a variety of regulations and requirements. Plus you get to join the hundreds of other dispensaries that have opened in legal states recently.
I decided that entering the industry wasn't for me. I'm not willing to risk the capital it would require with no guarantee on a return. I figure I could make more by investing in a mobile food truck and hiring someone to run it for me.
