"mega potent hallucinater thingy" wow. Just in case you aren't aware "hallucinogen" really isn't a proper word to describe these drugs; psychedelic or psychotropic substances such as psilocin, 4-ho-MiPT, DMT, LSD, mescaline, et al. potentially lead to much more significant changes in perception\awareness\consciousness well aside from just seeing things in your field of vision that "are not real". In a proper setting and at a proper dosage a substance like psilocin should produce in the person a virtual over-load of perception, a sense of becoming more aware of yourself and your environment (indeed realizing things that you may rather not, all at once over and over again...) and\or very drastic changes in thinking and behavior as the 'situation' to you may be quite a bit different than what it is 'actually'. If you haven't been introduced to psychotropics DMT probably isn't the one to try first. I haven't done it personally but there are books dedicated to the kinds of things one experiences when administered DMT (search: Spirit Molecule). It is commonly smoked (vaporized really) but can be administered via injection (IV\IM of sterile solution) or consumed orally with an MAOI (insufflation may also work). If consumed orally without an MAOI (monoamine oxidase inhibitor) the DMT would just be destroyed before it ever reached the brain. Mammals (even humans) evidently have some endogenous DMT in their brains, which may be produced in highly localized regions of the brain at certain times. Various plants, of course, produce some degree of DMT (along with it's brother 5-MEo) along with other animals including a certain kind of toad for instance which uses psychedelic tryptamines as a venom.
The effects, without an MAOI and administered through one of the quick routes, are short lived which is why they call it the "businessman's trip". It usually lasts 10-20 minutes if I am not mistaken, but is very intense. An MAO inhibitor at an appropriate dose may extend the duration to a couple hours or more. Psilocin (from mushrooms) is chemically very similar to DMT and orally active without an MAOI. It's a good starting point even though duration is longer (can make your body feel weird) the effects are probably more manageable.
