i say METH. hands down, worst drug i've ever touched. mostly because it tore me apart both mentally and physically. not to mention the fact that everytime i did it ...something really bad happened (physically). i don't know if it was my body's inability to break the shit down or what. but the last two times i smoked shit a long time ago... i got the most SEVERE and RAGING headache imaginable to man. it always felt like someone was shoving knives into my skull and twisting them into my brain and spinal cord. bad bad bad bad shit.
