It's a very subjective experience so I think there will be multiple opinions on this, however I believe it could help. I've seen people do some form of pre-dosimg to great effect. The census is that it eases that initial 'mindset shift' and body load dmt gives you. Which can be hard for some to adapt to and become comfortable with at first.
It can also act as a good 'test' to see if you feel like going deeper. Sometimes you take a hit too many and think 'maybe I wasn't ready for this' or 'maybe I took one too many hits', (which isn't an ideal mindset as you're blasting off). However, with a predose it gives you that additional 'safety net' of deciding 'no' maybe tonight I'm not feeling it and stopping, instead of diving in head first and getting yourself smacked into hyperspace with a worried mindset.
First few experiences can be nerve racking for many and for some, dmt takes a while to get comfortable with. Controling one's dose and how they dose can help.
Nothing wrong with just sending it either, you'll always come out the other side.
Personally my favourite thing to do is to smoke 25-35mg freebase harmala (whatever blend usually harmaline and thh) wait 5 mins then load 30mg of spice into the genie and take hits as I need. This way I can control how deep I want to go. It lasts longer than straight spice but I can decide to have a light visual experience, a short ayahusca like experience or if I go hard enough an extended dmt experience.
