This morning I took a 40mg Ritalin XR at around 9am. I have 2 more of the same pill and I opened one of them and crushed up a very small amount of the beads inside the pill (roughly 1/4 of the total amount). My question is, does snorting these crushed XR beads have a higher risk of harm than an IR pill? I'm guessing the amount i crushed up was around <10mg. I have no pre-existing heart conditions but I would like to know if the danger towards my heart health is high when doing this? I have noticed my heart is a bit jumpy and I feel very minor aches now and again. I haven't snorted any of it yet so any advice would be greatly appreciated. Thanks
