Color visual awareness

Crude preparations of mescaline (61) from peyote were first reported by the Spanish as they learned of its use from the natives of Mexico during the Spanish invasion of that country in the sixteenth century. The colorful history (44) of mescaline has drawn attention to its use as a hallucinogen and even today it is in use among natives of North and South America. Although in connection with dmg abuse complaints, mescaline is considered dangerous, it has been reported (45) that it is not a narcotic nor is it habituating.

Hallucinations of hearing, taste, or other senses were reported more rarely. Bradycardia, nausea, a feeling of oppression in the chest, faintness, and headache may also occur. 

QUALITATIVE COMMENTS (with 14 mg) I was well aware of things at the end of two hours, and I was totally unwilling to drive, or even go out of the house. I was reminded continuously of 2C-B with its erotic push, and the benign interplay of colors and other visual effects. 

An objective of the risk guidance tool is to develop a situational awareness of the potential for a loss-producing event.
