An extreme hallucigent. Effects depend on user's mood, disposition, enviroment, drug dose, etc.Drug does is called hits User may feel a slight "body buzz" shortly after injestion. After some time, user will experiance visual and auditory hallucinations. These hallucinations will either be extremely pleasent or frightening depending on user's mood, dose, and/or enviroment. Colors may seem brighter and more prevalent than usual, and sometimes, with higher doses, have "sounds". Users may hear sounds that arent there and the sounds they do hear may be somewhat distorted.Lines seem to be sharper and more prevalent, as if outlined with a black magic marker.Users may also see the impossible such as wrinkles upon wrinkles Bad trips may be extremely terrifing if the user is inexperianced and does not know what is happening. On a bad trip, a user may think that he is gone insane ,lost grip on reality, and will never know normalcy again. User's idea of self may be proundly affected, such as believing that he has become an amoeba, a fruit, or has become nothing at all. Bad trips can happen to all users, but experianced users may be able to cope with a bad trip because user understands effects of the drug. They know to talk to a friend, change their enviroment,not to be alone, and not to resist the drug. Resisting only makes things worse, especially if user is alone.
Acid will chage your life perspective, hopefully for the good, sometimes for the bad.

A powerful psychoactive drug that breaks down subconcious barriers and will make your mind race through the corridors of human perception. While under the influence you'll often hear people say "Dude Im trippin so hard" many many times as a way to come to terms with the phenomena that is occuring. Visual filters in the brain are broken down to let raw, unfiltered data in. It is usually hard to talk and move while your under the influence, so a suggestion would be to find a comfy chair, put some Phish on, and perceive.
Scott: "Dude Im trippin on acid"

Matt: "Stop trying to put a word like "trippin" to the experience your having, just flow with it man, if you fight the ocean you will drown!!!!"

In computer science, ACID (Atomicity, Consistency, Isolation, Durability) is a set of properties of database transactions. In the context of databases, a sequence of database operations that satisfies the ACID properties and, thus, can be perceived as single logical operation on the data is called a transaction.

It's also slang for LSD, apparently.
That database is not ACID, but this may not be a bad thing, if you understand the trade-offs.

Acid , LSD is the most powerful psychadelic drug on the streets. It will make you experience things you have never thought would happen. As a comparison, some think it as a video game, but in a more broader sense it gives your mind a very trippy effect and you can begin to see trails, dots, inanimate objects doing human things. Boosts Creativity a lot.
