My very best friend is burrying her 17 year old son today because someone showed him this unbelievable way to get a quick high with out drugs.  About 6 months ago my friend started to notice a change in her son and began to take action very quickly.  She took away his brand new truck, drug tested him regularly and he was always negitive.  On January 28, 2011 she walked into his room to wake him and found him hanging from a pull up bar that was not 5 feet from the floor.  The way he "designed" it failed.  It was supposed to release when he passed out and fell foward, obviously that didn't happen. My friend is the best mom and did everything she knew to do to protect her son, little did she know that what he was doing to get high couldn't be detected in a drug test.
