Sure dont look like canabis, but could be a super freak! If it is, I'd definitely keep some cuttings b/c if that thing flowers you have the #1 stealth strain going! Guess you will see what happens. But at 12/12, I think it would be showing preflowers/flowers at this stage of the game, seems pretty tall now? Leaves remind me of another plant, but cant put a name on it?? Tomato or peppers maybe?
