nope, but an old schoolmate of mine moked powderd bleach as a suicide attemp. he suvived..sorta, The damage it did to his body is slowly killing him. It fucked up his lungs really bad and as result he now has a sevearly enlarged heart. He needs a double lung and heart transplant, which isnt really possible so he dosn't have much longer to live. he smoked it in 1994 and was 13 at the time, spent about a year in the hospital after it happend. and hes had to use an oxygen mask ever since.
