So I've Been Experimenting Smoking Meth For The Last 7

So I've been experimenting smoking meth for the last 7 days, with two good nights of sleep in between. My question/problem is, my hands and soles of my feet feel oily and has a leathery scent. Is it in my head, or is it from the meth? Also, no matter how many times I bathe/shower, my hands and feet remain as they are (I think). Please let me know. Also, I'm staying hydrated and eating just fine.
