Contact high

Contact high is a phenomenon that sometimes occurs in otherwise sober people and animals who come into contact with someone who is under the influence of drugs. It involves a supposed transfer of the psychological state of height. A glossary of drug users' language from the 1970s describes the term as "a psychogenic 'trip' without taking drugs by being close to somebody while he is on drugs. It is incorrect to use it for the high obtained by inhaling the smoke of other marijuana smokers."[1]

The "contact high" myth is not true. The buzz that people often feel when they claim they are getting a contact high is actually the cause of the decreasing available oxygen supply in a confined location; they are feeling a buzz from lack of oxygen to the brain. You will not get a contact high, it is physically and chemically impossible. The smoke from the materials that are being smoked, and the smoke exhaled from the smoker are distinctively different. Using marijuana smoke as an example, the smoke exhaled from the smoker does not contain enough tetrahydrocannabinol (THC) to produce even the slightest effects on your body Tetrahydrocannabinol- active component found in the cannabis plant.

In Alexander Shulgin's PiHKAL book under the 2C-I entry, a notable reaction is observed in a participant who takes a placebo, existing in an environment with other people who are under the drug's influence.[2]

Stanislav Grof, together with his wife Christina, experienced a contact high assisting a person under LSD therapy described in his book When the Impossible Happens: Adventures in Non-Ordinary Reality (2006) in Part 4 about Pecherskaya Lavra (p. 213, in German edition).
