Partial glossary of terms used in TiHKAL
- Alert, n.
- The first clue that a drug will show activity. Each researcher, with experience, comes to recognize his own personal alert. It may be a tinge of lightheadedness, a chill, or a brief raising of the hair on his neck, and simply serves as a reminder that he took something half an hour (or a couple of hours) ago. Sometimes an alert can follow very soon after the taking of the drug, without any further effects becoming apparent until some time later. Each person’s alert tends to be experienced consistently, regardless of the nature of the drug being researched.
- Baseline, n.
- The normal psychological and physical state of a person prior to the start of an experiment which, once regained, marks the end of that experiment.
- Minus, n.
- On the quantitative potency scale (-, ±, +, ++, +++), there were no effects observed.
- Plus/minus (±), n.
- The level of effectiveness of a drug that indicates a threshold action. If a higher dosage produces a greater response, then the plus/minus (±) was valid. If a higher dosage produces nothing, then this was a false positive.
- Plus one (+), n.
- The drug is quite certainly active. The chronology can be determined with some accuracy, but the nature of the drug’s effects are not yet apparent.
- Plus two (++), n.
- Both the chronology and the nature of the action of a drug are unmistakably apparent. But you still have some choice as to whether you will accept the adventure, or rather just continue with your ordinary day’s plans (if you are an experienced researcher, that is). The effects can be allowed a predominant role, or they may be repressed and made secondary to other chosen activities.
- Plus three (+++), n.
- Not only are the chronology and the nature of a drug’s action quite clear, but ignoring its action is no longer an option. The subject is totally engaged in the experience, for better or worse.
- Plus four (++++), n.
- A rare and precious transcendental state, which has been called a “peak experience”, a “religious experience,” “divine transformation,” a “state of Samadhi” and many other names in other cultures. It is not connected to the +1, +2, and +3 of the measuring of a drug’s intensity. It is a state of bliss, a participation mystique, a connectedness with both the interior and exterior universes, which has come about after the ingestion of a psychedelic drug, but which is not necessarily repeatable with a subsequent ingestion of that same drug. If a drug (or technique or process) were ever to be discovered which would consistently produce a plus four experience in all human beings, it is conceivable that it would signal the ultimate evolution, and perhaps the end of, the human experiment.

About TiHKAL · info
This version of Book II of TiHKAL is based on the Erowid online version created by Bo Lawler with the help of Erowid, from content generously provided in electronic format by the Authors.
The Erowid online version does not always align precisely with the printed version. Text appears to have been inserted, deleted, or changed at various points. Where the two are seen to diverge both the Erowid and print versions are given. Sharp-eyed readers are encouraged to report novel discrepancies.
As with PiHKAL, I’ve again attempted to reproduce the typographic style of the printed edition. I’ve again made minor changes to some chemical names in line with current nomenclature practice. Typically the change is little more than expanding a prefix or setting it in italics. The history page has further details.
“At the present time, restrictive laws are in force in the United States and it is very difficult for researchers to abide by the regulations which govern efforts to obtain legal approval to do work with these compounds in human beings.“No one who is lacking legal authorization should attempt the synthesis of any of the compounds described in these files, with the intent to give them to man. To do so is to risk legal action which might lead to the tragic ruination of a life. It should also be noted that any person anywhere who experiments on himself, or on another human being, with any of the drugs described herein, without being familiar with that drug’s action and aware of the physical and/or mental disturbance or harm it might cause, is acting irresponsibly and immorally, whether or not he is doing so within the bounds of the law.”

TiHKAL is the extraordinary record of the authors’ years exploring the chemistry and transformational power of tryptamines. This book belongs in the library of anyone seeking a rational, enlightened and candid perspective on psychedelic drugs.
Though Sasha and Ann have put Book II of TiHKAL in the public domain, available to anyone, I strongly encourage you to buy a copy. We owe them — and there’s still nothing quite like holding a real book in your hands.
