I took speed at 4pm today, it kicked in at 11pm

I dont understand what's wrong with my body. I've taken speed before and it's either never kicked in or taken hours or other drugs to start kicking in. I dried the speed on a hot metal plate and then crushed to a powder and made lines which I snorted with a friend. Why do i have such a weird amphetamine resistance? Meth also doesn't work like it does with most people, it takes long to start kicking in. I was even laying in bed and almost fell asleep but the speed kicked in like a bus crashing into me.
