a simple question however im finding alot of mixed answers.
My plan is to powder 4 grams of rue and drink down with juice before taking DMT
how long should i wait before the DMT becomes active

I don't recommend drinking rue powder. You can literally make a tea in minutes if you're really in that much of a hurry.

If you search around you'll see that people dose differently. Some take them at the same time, others a few minutes apart, some 20 minutes apart. I just wait a minute or two. Try it different ways and see what works for you.

When you look at ayahuasca use in the amazon, the DMT and harmala containing plants are mixed together and ingested at the same time. Always works for me, but for some this doesn't seem like the most effective way. Individual differences are big here.

Best of luck

Yep, I used to always brew the plants seperately, but lately I've been doing them together. It may be a little bit less efficient but I usually use a bit more force and split the dose in two.

I always feel the harmalas within minutes, then later the light kicks in.

Just a warning

For me, taking rue without removing seed material was a terrible, terrible experience. Some of the worst nausea I've ever had and endless vomiting. Definitely make a tea.
