I tried meth for the first time at my one of my buds parties. I drank 2 beers, 2 shots, and hitting my thc cart “white widow”. I also took a 50mg anti depressant. I was going to do some cociane but the dealer gave us meth instead... Good thing I didn’t pay for it.

Summary
N-Methylamphetamine (also known as Methamphetamine, Ma, Meth, Glass, Ice, Shard, Crank, Tina, T, Tweak, Yaba, Shabu, and Crystal) is a classical stimulant substance of the amphetamine class. It is structurally related to amphetamine, however it crosses the blood-brain barrier more rapidly, due to its relatively high lipid solubility. It produces its effects by increasing levels of the neurotransmitters serotonin, dopamine, and norepinephrine in the brain.

Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Acute tolerance builds rapidly over one or more long sessions, with noticeable blunting on subsequent doses; partial reversal occurs over 1–4 weeks if abstinent. Data are largely observational/anecdotal from user communities rather than controlled studies.

I wrote this to relate my first meth experience to others, so that they may make an informed decision regarding their own use of it. I am not recommending anything. To use or not to use is your decision. Cocaine is my drug of choice, I know the ritual all too well. Buy, chop, snort, feel the rush, ride the rush.
I first tried crystal meth about two months ago, and have so far found it to be a wonderful drug with remarkably few negative side effects, despite all the bad press it receives.
I couldn't resist writing about a lone incident this past summer that I liked a lot, but didn't have the mind to do again. Before you continue reading, don't get the wrong impression; I did not have a bad tweak-- it was AWESOME.
The last few days that I spent in San Diego forever changed my life. I was coming off of crystal meth really hard, and even going through that hell, I remember almost every second of those days clearly. It is something I will never forget, when my whole life came down to one split-second decision.
Late August 2003 - Introduction to smoking meth amount smoked: minimal, two or three small puffs. sensations: slight elevation of alertness, already happy feelings were mildly enhanced by less self-consciouness (we were on a trip out of our small town for a weekend Gay Pride fiesta) mid October - second meth experience...
Confessions of The Midnight Tweaker: The Finished Paper Written in late July, 2001, by an 18 year old white suburban Phoenix male. Foreword I have been using crystal meth regularly for approximately seven months.
I loved Crystal. Whenever I remember her, all the unpleasant memories are conveniently set aside, and only the good remain. The first line! The perfect line! I missed her, so I wanted to find her again. I called my dealer again 3 months earlier than I had told myself to wait to see her again.
This is my story. It's a bit of a read but I wanted to share a bit of everything I've gone through, to really give readers an idea of what exactly meth is capable of. My heart breaks for those of you also battling an addiction to meth, and for those who haven't signed your life away yet, don't do it.

Hello, I intend to be as objective as possible. I read a lot about crystal meth, trying to research everything before the experience. So I wanted to add to what's there and here is what I found after my first time (last night).
I understand that trip reports usually focus on illustrating a single experience under the influence. Arguably, my dependency on meth has generated an altered state for much longer than a "trip", and it can even be considered a trip in itself.
Junk Mail, Part 2 "262,992 Hours: Diagnosis; and, Thrombosis." (Methamphetamine [IV/oral], Cannabis [smoked], Alcohol [oral]) I’ll start the day before yesterday, sometime between midnight and midnight. No, I can be more specific than that. It was daytime because the sun was out. That is all I know.
(Crystal Methamphetamine 1g) - somewhat experienced - Observations and Insights Part2 Disclaimer: I cannot say if this will be worthwile or useful, however it does include things i consider worth mentioning re meth and side effects.
Guys, took an uncomfortable dose of crystal, it would really make me feel better to write a report about my general meth experiences to distract me from the overstimulation. Hope it makes sense. Be warned, its long and awesome. Oh and unlike every other meth user, I know how to use paragraphs.
Alright, so I essentially had one of the worst nights of my life yesterday. It involved alotta meth ingested orally leading to a full meth psychosis. I apologize if the size of this thread discourages some it's both a trip report i had to tell to someone, as well a sort of introduction.
First let me preface that before this particularly scary experience my feelings and thoughts towards meth were amicable. I've smoked it a total of 4 times with my friend (who was addicted to it for about 6 months) as well as a guy friend (fwb, who also had a lot more experience with it than I did).
