Upstate NY: can I work at a dispensary at 19?

I've had a plan to work in the cannabis industry for years now it's my dream and passion to work with the plant I love so much, I don't know where to start I know weed is gonna explode in the states I want to get in the game before it's too late. I was thinking of working at a dispensary but I'm unsure if I even can at 19 when looking it up I get mixed signals about the laws. Anyone able to help out? I want to know if there are even any jobs relating to weed that I can pick up because it at least points me in the right direction.
