Can anyone roughly identify a plant by looking at this leaf?

So I was gifted a few seeds back in 2016, and finally decided to grow it out. I have no idea or remember if that person even knew what it was. Just looking for some input, a rough estimation and thoughts as to what phenotype?

I believe it's cannabis........but I could be wrong.

Sativa-indica cross, but these days most everything is a cross.

the cops once told me, during a bust we can test those leaves and tell if they from different strains you know, ask a cop nicely, he might run some tests for you
