my sister has a few pills that she says are 2 mg xanax bars she said they are the new ones that can't be crushed they area kinda tan or white with tan flecks and they have no writing on either side they look like xanax bars except theres no print and them color is different has anybody ever seen these and if so what are they. Also they do have them four lines on one side to break them them other side is smooth.
