It has been a long time since I had Kadian. The best way to dose/split one of those would be:
1. dump all beads into a shot glass
2. crush the beads until well powdered, the butt end of a small screw driver works pretty well.
3. add 1ml of water for every 60mg of morphine.
4. Allow to sit for about 15 minutes to one hour, stir now and again to agitate and squeeze beads to help release any morphine that is stuck to them (syringe plunger works well for this). Do not add heat it's not needed and will allow the wax from the beads to end up in the solution.
5. Draw up with oral syringe and dose orally or rectally
This will make the morphine instant release and allow you to split the dose if you want. 0.5ml would be equal to 30mg assuming you started with 60mg of material and follow the rule of 1ml of water to 60mg of morphine. I'm quoting this off the top of my head but I'm pretty sure 60mg is the max amount 1ml of water can hold. I always added 0.3ml extra to account for the wax/beads as they absorb some water. I also drank the beads by adding extra water to the shot glass after I'd taken my dose. I used Kadians as a source for morphine for about a year and always plugged/boofed them. Kadians are easy to work with and one of the easier morphine preparations commonly prescribed to work with.
Counting the beads isn't a good idea because they vary in size. Kadiens are designed to be an ER medication so the beads hold different amounts of morphine and are designed to release the morphine at different rates. Even if you decide not to use the water method you should crush the beads if you want IR morphine. If you take them as is be aware that you'll be dosing an ER medication and might not get the effect that you're looking for. As always opioids are easy to get addicted to so be careful with these.
Do not snort morphine as it's a waste. Rectal is the best ROA excluding needles. Oral works well but requires a lot of material to reach a nod when compared to rectal. If you're going to IV make sure you have a wheel filter and use proper technique. A friend of mine nearly lost his arm to shooting up Kadiens without properly filtering them and they're a lot cleaner than most ER morphine tablets.
Happy nods.
