Why not get a puppy? Go Skydiving? Travel? Basically anything other than doing a drug that can seriously harm your health and lead to a variety of problems down the line. You're of course welcome to do whatever you'd like with your own life, but I honestly can't comprehend that someone would willingly try such a dangerous drug simply because they're bored. How do you even arrive at that conclusion of "You know what, there's nothing left for me to try except heroin."
