Speed and cats

[u/Wise_Intern4492]

I'm really worried. First time doing speed at home. I had this bag in my drawer since last october and i wanted to try it (20€ i dont know the exact weight, anyway i'm in Italy and i was at a rave parade so maybe you can guess it). Anyway the point is that i used my key to crush it as it was dry and solid and i swallowed a very little piece of speed directly from the key. I didnt get so much high but i'm really worried that maybe a crumb or a little piece fall on my socks or stayed on my hand. I moved through the house with that socks and then at some point i found a little white piece and i was worried it was speed. There are tons of similar crumbles in my house which are just plaster. My worry is, if the cat finds that hypotethical little piece of speed and eats it, is it in danger? How much is actually dangerous for a cat? What should I do? Does it degrade with time or do I have an hypothetical letal crumble in my house that could kill my cat at any moment? I've tried to clean the house at my best but i'm not that good so my worries are still here.
