The foam is the vapor barrier.
For the most part, the only way you can get into trouble is if the foam ever shinks away from the framing, allowing air around it.
Foam is not technically a vapor barrier and is some applications it is required to add a paint layer as a vb.
Having said that, not to worry as long as you have 2 or more inches of it you'll never know the difference.

This afternoon, while watching my daughter in a field hockey tournament, from out of nowhere the thought "I really should go back and clarify my foam/VB post" popped into my head.
Well...maybe not "from out of nowhere"...it could have been the 42 degree temp and the 11 knots of wind (that's just about a double five point five for you true northerners...five point five centigrade and five point five meters per second) that made me think about it.
