small light green tablet, NO imprints, scored in half on one side, circle shape

I bought this from xxxxx.com, it came in a blister wrapper of 10 pills with the Nozim-2.  I ordered Clonazepam 2 mg tablets. I had taken one, an did not notice any effect. Could this be fradulent? I have tried searching for the Nozim company online and could not find anything. Any help is welcome!!! Thanks!
