Are they a lot bigger than your usual ones? If so, they suck IMO. I can't fucking stand the big ones that are impossible to IV and create way too much powder when crushed for snorting. However, my preferred ROA is IV but I remember them not being great by snorting either.
If they're bigger than usual, you need to find a new pharmacy that carries the smaller ones. I used to prefer the Qualitest brand roxies but I've gotten to where I like ANY small roxy instead of those big ones.
