lol i'll actually answer your question since i figure youre gonna do it whether someone helps you do it best or not. there is no real starting dose. i'm assuming youre talking about black tar heroin. you should get whatever quantity you feel comfortable buying, and using a knife and a flat piece of glass like a picture frame, put the heroin on the glass and cut off a circular piece with a diameter of a couple millimeters. you can do it much larger, it doesn't really matter. then, you should cut a square piece of foil about 6 inches by 6 inches. i actually used to do 6 inches by 8 inches. run a flame across both sides of the foil, don't hold the flame in any spot for longer than half a second. just kind of flicker the lighter across the whole thing. contrary to popular belief, it doesn't matter which side of the foil you use. the reason one is shiny and one is dull is not because of a coating, but because the machine brushes one side with tiny metal bristles. put the circular piece on the foil. push it down very lightly so that it doesn't smash the ball. you don't want to push hard enough to deform the ball at all. but you want to push enough so that when you hold the foil at a 90 degree angle perpendicular to the ground, the ball does not roll off. ideally you want a good little sphere thats stuck just very slightly, so that when you put a flame to it, it drips down rather than staying in the same spot. now, for a tooter. i would get one of those typical black bic pens, the really cheap ones. take out the pen tip, and using scissors cut the other end off so that you end up with a tube about 4 inches long. now stick this in between your two front teeth and close your lips over it. now i forgot to mention, you want to put the ball of tar near the upper right corner of the foil, so that you can hold the left side of the foil with your left hand, and with your right hand you can hold the lighter directly underneath the ball. there should be at least half an inch of space between the ball and the edge of the foil, both the top edge and the right edge. so it's not actually ON the northeast corner of the foil, but rather NEAR it. the foil should be at at least a 45 degree angle to the ground. the ball of heroin must drip down. i would usually do much steeper than 45 degrees, honestly like 70 or 75 degrees. but be more careful the first time until you get the hang of sticking it on there to prevent it from falling when you tilt it. now, the flame of your lighter should not actually touch the foil itself. it's okay if it does a little bit but you're wasting heroin and you could evaporate tiny pieces of aluminum if you hold the flame too close to the foil, and for too long. so you gotta look to the side and do a few practice runs before you burn the real thing. see where you should hold the lighter if you want the tip of the flame to be a millimeter away from the surface of the foil. you want the foil to get hot, but not burnt. so the tip should just barely hit the foil, in exactly the spot where the ball is. you'll probalby have to move the lighter around a bit until you find the sweet spot. and of course since youre holding it at an angle, the ball will immediately start rolling down the slope, and with your lighter in hand, you have to follow it. you want to be holding the tooter half an inch to an inch away from the ball at all times. so as the ball falls down the foil, you follow it with BOTH the tooter and the lighter. eventually the ball will get close to the bottom right corner. at this point, you want to rotate the foil counterclockwise 90 degrees, so that the bottom right corner becomes the top right corner. this way, the ball of heroin always stays in the top right corner and you never have to switch hands. just keep doing that until you form a spiral that takes up the whole foil. rinse and repeat. but honestly if you're a first time user, you should be pretty loaded within a couple hits. remember to inhale as deeply as possible and hold your breath as long as possible. you will know when you've had the "starter's dose" because you'll be nodding out, warm, euphoric, and your face will just feel fucking awesome. don't be scared, it's exactly like any other opiate and nobody has ever died from smoking heroin, to my knowledge. you would throw up or pass out way before you smoked enough to die. just make sure that if you pass out, you're lying on your side not your back because people have been known to die from choking on their own vomit, as you may already know. if u have any other questions you can PM me. and finally i should say that you should ignore everything i said and don't do heroin at all, but i know you're not gonna do that. but i hope you realize that however pleasurable you think heroins gonna make you feel, quitting it is gonna make you feel EXACTLY that shitty. 10 points of pleasure now equals 10 points of agony later on. i tried to kill myself because of it. it's serious shit so i hope you take it seriously and don't do this shit daily. you could walk out on the other side of addiction and end up fine, but it's not super likely. it would be a lot better for you to moderate your use off the bat. set some rules for how often youre gonna do this stuff, and don't break them. not even once, because once leads to twice. good luck
