acid-The wonderful gateway in your pocket to a world that is yours for the creating, whether it be talking frogs, stary faces on apple trees that just wont blink and you're sure that they know your name or maybe just the good old headmash that convinces you that you ARE, in fact, a carrot.
A truly marvellous man made hallucinogen that could, one day, replace calpol.

Acid was a drug created by the CIA for various purposes but was effective at none of them. Acid was then found to be a catalyst that people used to open the doors of perception. Often people truly felt they had gone to heaven, taken shots with God and He enlightened their brian with the love that only He could. After twelve hours God would send the person back to somewhat normalcy but the memory of the visit to God would always be remembered. Subsequently, scientists proved this to be true and tried to ban the substance and use propaganda to be able to horde it for themselves.
I'm going to church but I need some acid first.

1.) A substance such as lemon juice, rain, obviously acid rain, or milk, that have a pH of under 7.0. They conduct electricity, and have a sour taste. Weak acids (milk & rain) don't have much of an effect on human skin (although they have a horrible effect on teeth). Strong acids such as acid rain & battery acid (especially car) will "eat away" your skin and flesh probably up to the bone.

2.)Lysergic acid diethylamide, LSD, LSD-25, or acid. A very, very, very, very, very, very, very, very, very, very, very, very to the 9000th power dangerous that a gram of it can kill you many times over.
A few micrograms can make you high for eight to twelve hours. In the late 50's to the early 70's, it was probably the most common deaths among hippies other than random violence.
1.) Acid is the opposite of base or alkali.

2.) It takes over 9000 micrograms of LSD to kill a human many times over.

A powerful drug that has a high concentration of hydrogen ions, which therefore makes you have a tripped out feeling. crazy.
