well just because something is usually used one way, doesnt mean it cant have other uses... just think of mdma, that gets people raving all the time, but is known to have therapeutic values...
5-meo-mipt is known to be able to provide deep experiences especially in the later half of the trip. i lends itself quite nicely to ruminations on the past, thoughts of the future and things of this matter, but i find low doses to be best (but then again, im always loving a low dose of anything). do what you feel right, in the end, these drugs are only keys to doors in our own mind, they do not create the rooms that come to light. use them, not the other way around, and you will have your effects.
for me, a low dose, some chill oldies music, a warm blanket, and i was reminiscing my childhood while embracing the happy moments of vacations gone by. a real battery charger.
about ROAs... given that the doses are this small and it is so well absorbed orally, i ask again, why bother with anything else? that being said, im pretty sure i heard of people sniffing it and plugging it. sublingual not so much as the taste gets most people...
