What would happen if someone managed to create a machine that continuously pumped DMT vapour into their lungs? Since after around three hits the trip begins and you can't inhale anymore without assistance, what would happen if you continued to inhale DMT?

Once you go over a certain dosage (per the individual) - you'll just black out or not remember any of it due to the intensity and amount of experience that ends up pouring through.

Deeper you go in - the harder it will be to hold on to ime (until you reach the point I'd said above).

The whole 3 hits thing is funny too to me. People shouldn't try to fixate on the '3 hits' phrase imo. 3 hits definitely aren't needed if you'v gotten everything else squared away before you start toking.

I read a study is in development (IIRC, the UK) where a constant DMT drip is in place to explore extended trips. I wonder where this process is currently.
