A description of the experience

Perhaps the most beneficial aspect of the gas experience is the personal ‘revelation’ or insight. These confrontations with individual fears and problems occasionally are of such magnitude as to plummet the person into a nightmare of self-doubt and madness. Similar to LSD, the revelation can be magnified and distorted until it is uncontrollable. Unlike acid, this experience on gas is transitory, erasing itself with the next inhalation. Because the nitrous oxide facilitates the release of unconscious material it has great therapeutic value – providing profound changes in a person’s value belief system and self image.
