I just took about 7mg of edibles. What should I expect?

I've smoked weed before but I now live in a state where it is legal for recreational so I went to a dispensary after work and got a chocolate bar. I've never tried edibles before. I took about a piece and a half and the bottom of the hour and am now just hanging out waiting for it to kick in. I have no frame of reference for how much a puff is in terms of mg so I'm a little lost in terms of what I got into
