First time ROA's and Effects: Read IV Warning!
My advice to you:
Please do not take it through the needle. While it feels better and is incredibly more intense than anything I have ever felt in my 25 years of life, taking it via syringe as a first timer (if ever) is a BIG mistake. I promise, even before I took my first shot some kind addict offered me the same advice and I should have taken his warning a lot more seriously.
SMOKING:
As for your first time, depending on many factors (hydration, body weight, mood, dosage) many things or nothing at all could happen. The first three or four times I smoked meth I didn't notice any effects whatsoever. All my friends were bouncing off the walls while I sat there clueless wondering why I wasn't so noticeably happy as well. If you have a boy/girlfriend, keep them close as you will more than likely have an intense ambition for sex. Your heart will race, you will feel a rush in your body that nothing else has ever produced, you will feel whatever emotion you feel that you lack, for me it was powerful. I felt like I could do literally ANYTHING I wanted. I had a tremendous amount of energy, like I could ride my bike for miles and miles (and I have) without getting tired. You're heart will be beating very fast and it could be scary, causing you to wonder if you're going to have a heart attack. You're vision could get blurry, I think this is caused by high blood pressure (don't quote me on that) and if your eyes do get blurry, you will l probably shake, not like a convulsion, more like a vibrator. People will ask you if you are okay, and you will just nod because you will be at a complete loss for words and physically unable to speak, unless you really try, but will be feeling great. You will be more eager to do anything you want to, and even if you don't want to, you might do it anyways as "courage, drive, ambition, etc" might be the word(s) of the day for you.
The rush lasts only a little while , 5-15 minutes tops. Next, you will come down to a feeling of "still fucking awesome, but not quite as awesome as the rush". If you kept you're boy/girlfriend handy, this is where they come in and if they are as high as you are, you might turn on a bit of pornhub and go to town. Even if porn isn't normally your thing, it might be. (if you are into it give xnxx.com a try; good selection HUGE collection, and no computer problems/viruses to date). Gum might be good too, as well as STAYING HYDRATED, especially if your activities include making sexy time. Even if it is difficult to get anything down, get some down. Since hydration is KEY, gatorade/water/REAL lemonade(not high fructose corn syrup or mix, lemons and water w/ sugar) because soda will dehydrate you and make your come down worse. If in public areas sunglasses are good. Your pupils are HUGE and if you have lighter colored eyes, you might wonder "do my pupils look big", and the answer is yes, bigger than mickey mouses, put on your shades. If you are planning to be around people who won't be happy about your decision to try dope, make plans to be elsewhere.
CRASH:
So after the 12-15 hours you will come to a point where to your dismay, you will no longer be super happy, but kinda sad. Welcome to your comedown. Your body will be exhausted, sore, and you may have a headache. Ibuprofen helps the soreness and headaches. Just like how hydration in important before and during, its equally (if not more) important when coming down. You might feel "off" the next few days and after you recover from the comedown, you might be down to buy some more, if so you should fight the urge and do something else. Laying in bed, blinds closed, and a movie is how I prefer to comedown. Smoke some weed if that's your thing and hope you didn't do anything you have come to regret by now. I don't recommend going to work, church, a party, grandmas house, etc as you'll just want to lay in bed. This is the point that gives birth to what we call Drug Addicts. I am a drug addict, most of my friends are drugs addicts, many people who post in the forums are drug addicts or recovering drug addicts. Anyone who tells you that doing it once is harmless and an ignorant cheese dick and is likely full of shit.
Snorting: Snorting it burns like a motherfucker, has a more intense high, but doesn't last as long. It's onset is a little faster too. It also drips down your throat and tastes like chemical flavored shit, but it is more intense and you don't need as much with smoking to get loaded.
Oral: Oral takes anywhere between 20-60 minutes for onset and is a bit more steady and kind of cleaner feeling, less OCD. There isn't too many ritualistic qualities about it. Crush it, wrap it up in a tiny corner of a kleenex and swallow it down with water/gatorade etc. I preferred this method when I had to go to my daily grind at the call center because it kicked in subtly. (then again I did every ROA with the exception of IV because I wasn't into that yet without many people noticing)
Booty Bump: I personally have never booty bumped. Google how to and effects, because I have never been too inclined to shove a (needless) syringe full of something made in some bikers bathtub in a trailer park somewhere up way into my ass to get high. I've heard its about as intense and the effects as long lasting as IV.
Before I begin the final method: Slamming, shooting up, banging, IV, injecting whatever it is that you might call it is the same thing and is a really great way to become addicted to meth. Just as a warning, school NEVER could have taught me about the horrors on drug addiction and the suffering it will bring. Notice how I used the word "WILL". Not saying you WILL get addicted, but if you get addicted (and the odds are very high) you WILL suffer... you're family, friends, coworkers, people who care about you etc will all suffer. I don't think any addict would be okay with handing this burden to anybody else, but it happens. Keep in mind, Each addict is responsible for their own addiction. If your friend introduces you to dope/any drug, and you get addicted to it, it is YOUR fault. You might feel like its their fault, and it might be convinient to blame them, but you're the one who was curious and touched the fire, even though you were told it was hot, you didn't care and did it anyways, then you got burned with a blistering addiction and a really big problem that you'll be carrying (hopefully managing more that not) for the rest of your life.
Intravenous Injection: You will be so incredibly impossibly magically, think you're heart is going to explode out of your chest fucking obliterated HIGH! Your eyes get blurry, you shake, you get the chills x1000, you feel happier than you have ever felt in your entire life, your skull will be fucked with enjoyment, you think "HA! They said I wouldn't EVER feel as great as my first high, and I guess they were right, because I feel WAY FUCKING BETTER". OCD tendancies are much less, with smoking and snorting I become obsessed with "more, more More, MORE, MORE), with a shot its poe, slightly pull, red squirt, slowly push, K its all in, blackness, calm, calm (eyes get real big... oh shit) BLAST OFF! Yes, my first shot of meth was so intense that I momentarily passed out... before exploding with more energy and excitement that my pale red-haired ass had ever had before, even already being addicted to meth by way of smoking. My penis was just as happy as the rest of me, but Little SharpMetalMulisha was so happy he too passed out. If you ever take it through the needle, and enjoy this rush, ENJOY IT, because this time you won't chase that high again. You won't want to smoke, snort, eat, or shove it up your ass because you'll think it'll be wasting it. You will be like Smeagle from Lord of the Rings and meth will be your "Prreeciiouuuusssss!!".
If you don't use, don't start
if you started, just stop
if you can't stop, then get HELP
without help, you won't recover
if you don't recover, your days are numbered.
