A crystalline compound, C20H25N3O, derived from lysergic acid and used as a powerful hallucinogenic drug. Also called acid.
Wow that was some potent LSD.

contrary to popular belief, hallucinations do not always occur with the consumption of lsd, low doses cause an altered state of mind. The drug does not itself give euphoric, nor negative feelings, although, when the user is in such a mood, it will enhance it.
dude 1: how do you feel?
user: different, but i dont know how im different, i just know im different.
*user giggles for a prolonged period of time*

Love Simple Deathless

LSD can expand your awareness and perception. It can evolve your understanding of life, the universe and love and the nature of reality and yourself. It's huge! It can be incredibly theraputic. It is very important to be with someone who is NOT judgemental and someone you TRUST. Who will be a "trip sitter" with you - whom you can talk to and share your insights and feelings if you need to. I highly reccomend being in nature as a way to connect to life. That is Sooo MUCH better than tripping in man made and other artificial unnatural environments. I love music etc., but solitude is very important to process the insights that come up.
Safety, trust and nature - are VERY important when you are tripping - for you are VULNERABLE when you are tripping. It is possible to have a bad trip if someone predatory violates your trust - like a cop or a sexual perv for example. On a 'bad trip' instead of connecting to life and love, LSD reinforces your fears instead of your capacity to feel, recieve and give love. Be careful! cuz LSD can have _long lasting_ postive or negative effects. At its best, LSD is transcendental and can help you advance your consciousness. I prefer psychdelic mushrooms instead of synthetic drugs. In anycase, approach with respect and don't give into fear. Its not just about recreation but about wisdom and evolving your consciousness as a human being.

A life changing experience unlike anything you can imagine. Every "Thing" has its extra something. You can look at things and taste it. Pretty much unexplainable. Bad Trips all depend on what state of mind you have. Your life can change for the good or for the bad. Rediculously powerful.
It all starts with a peice of paper...
After bill took lsd (acid) his life changed completely.

D-Lysergic Acid Diethylamide. A semisynthetic psychedelic first synthesized in 1938 by Swiss chemist Albert Hofmann, later used in psychiatric research and mind-control projects by the CIA (MKULTRA). LSD gained popularity in the 60s with the counterculture, and was quickly criminalized in 1966 in the US. It is a solid crystal, melting at app 175 deg. F, although it is highly unstable and is destroyed by heat, air, and esp. Chlorine.

Dose: LSD is most commonly found on blotting paper, sometimes in sugar cubes, aqueous form, or as small pills called microdots. The threshold is 20mcg (mcg-microgram is one millionth of a gram). In the 60s you could find doses about 500mcg, nowadays a usual dose is around 20-100 mcg, commonly in the lower range. Thus LSD is never sold adulterated, it's impossible, but it is not uncommon to find other psychoactives such as MDMA laced with LSD.

Effects: Come up is 30 min-1 1/2 hr, a trip lasts 6-14 hours depending mainly on dosage. LSD causes blood pressure and heart rate to increase, as well as salivation and perspiration. Extreme emotional changes take place; whether they are good or bad depends on set and setting. Time and space are heavily distorted, surfaces may seem to ripple like water, walls might appear to breathe; sounds are also quite distorted. A crossing of stimuli normally takes place, this means one senses, most commonly, seeing sound, or tasting color. LSD can also cause nausea, panic, and, at much higher doses, psychotomimetic effects.

Traffick: Since the early 21st century, the price of LSD has risen dramatically. Another definition says it is one of the cheapest drugs; this is untrue. It is one of the cheapest drugs to manufacture, but the consumer can expect to pay $10/hit, $90 for ten, or sometimes 2 for $15. The price rose about 6 years ago after the Pickard/Apperson bust. Pickard/Apperson labs were responsible for the majority of acid produced domestically; about 100 clandestine acid labs remain in the US, most in northern Cali.

Chemistry: LSD is synthesized most commonly from lysergic acid, or lysergic acid amides which are found in Morning Glory seeds, Hawaiian Baby Woodrose seeds, Ergot (a fungus that grows on rye), and possibly sleepy grass. LSD production requires many organic solvents, app. $5000 worth of glassware, and a couple years of organic chemistry. It is very difficult and dangerous, don't try it at home.

Toxicity/Myth Debunking: LSD is non-toxic to the body, the LD50 is somewhere in the 12,000-14,000 microgram range; the only overdose involved 360,000 mcg of LSD... most acid chemists don't even manufacture that much in one batch. It does NOT stay in your spinal fluid (flash backs and HPPD are rare psychiatric disorders), it is metabolized rather quickly into an inactive analogue. It does NOT cause your brain to bleed. Most acid heads will tell you it does, but acid heads are morons. Strokes, intracranial hemorrhaging, CVA, and annuerysms cause your brain to bleed, not acid.

LSD is a rather sophisticated and complex drug, so basically... It makes you trip balls!
C: I just ate seven hits of LSD.

C: No, that's for when I eat a ten strip.

LSD (lysergic acid diethylamide) is a synthetic hallucinogen for which no natural sources exist. Closest occuring natural compounds are the LSAs and ergot. Usual dosage 25-500mcg.
