Well, I live in California where it's perfectly legal to grow and smoke pot for people who have 215 cards, meaning it's medically prescribed. There's not a darn thing that can be done about it.
My neighbor smokes pot like she invented the stuff. We smell it all the time.
But, I really like my neighbor. She is super nice, honest, she watches out for things when we're gone and we look after things for her when she's gone. She's an amazing cook and always brings us things that she makes. We do the same for her. In the scheme of things, smelling pot is the least of the problems a person can have with a neighbor.
I understand your situation. I have friends who could care less if people smoke the stuff, but they are allergic to it so they have to close their windows and things too when their neighbors are outside smoking it.
I suppose you could talk to the guy nicely and let him know that you can really smell it. Maybe say that you don't want in his business or care what he does really, but you have concerns about your kids and the kids you teach smelling it.
He may be really nice about it in return and say that he didn't realize you could even smell it. Maybe he truly doesn't. People from all walks of life smoke pot and perhaps if you approach him the right way, he'll try a different spot in the yard or something. It's worth a try.
No matter where he goes in the yard, there will be some days if the wind is right that you will catch a hint of it.
I work at a hospital and I swear I smelled it in the parking lot when I went from my office to take charts to the surgery suite. It has a distinctive smell, to be sure.
If this is a nice family and they are good neighbors aside from this, I would try gently mentioning something. I wouldn't make threats.
Heck, I might be tempted to mention it about half an hour after you smell it while the guy is feeling particularly mellow.

Kids are taught that drugs are bad in school and at home, but then we also have to explain why it's okay for some people because it's considered their "medicine".......at least in California.
I wouldn't get the police involved first thing.
I don't know the specific laws in NY, but unless he's a major dealer or something, the most he would likely get would be a ticket for misdemeanor possession of a joint or something.
I hope you can find a compromise.
Best wishes.
