I'm getting some Oxycontins soon. Most likely 4 pills, either 40mg or 80mg. I've done Perocets and Oxycodone pills before, the 5/325 ones, and I just take 4-7 to get a good high. Do I just scrape off the time release with a razor? How do I know when I've gotten it all off and does this work? How much should I snort for my first time, and should I snort some and just down some? Thanks in advance.
