DMT (dimethyltryptamine) is the most powerful and fast-acting of the tryptamine class of hallucinogens. After smoking DMT users regularly report fantastic trips to other dimensions and conversations with intelligent alien life forms. Meyer outlines DMT usage, pharmacology, mythology and occult application, including shamanic uses. He also presents fascinating anecdotal material regarding DMT "alien contact." Materials from DMT researchers Terence McKenna, Gracie and Zarkov, and dozens of other correspondences are included, providing clues to deciphering the DMT "hyperspace" state.
