Welcome to the Nexus!
Like Homo Trypens said, it's not necessarily about answering all the questions "right", its just one more feedback we get from new members to see a bit of their previous knowledge and most importantly, attitude. As for the acetone question, a lot of things dissolve in acetone, but as it relates to extractions, it dissolves most plastics so gotta be careful during extractions to use the right tools and containers. And it dissolves freebase DMT well but not DMT fumarate (hence why the FASA tek works).
Let us know about your vape/mod experiences. Personally I just have a vaporizing pipe (GVG in my case but there are others you can buy or make yourself) and use that, its another option you can consider if you want to not strain your lungs
Are you also interested in oral dmt/ayahuasca use?
As for the questions you have, it's all good! Gotta fall in love with questions, because in terms of the experience itself, it generally leaves you with more questions than answers, and regarding the subject of DMT/psychedelics/chemistry/pharmacology/etc, this is also endlessly fascinating and there are always more questions to be asked
Just make sure to read the main resources available, FAQ, stickied threads, etc, and then jump right into our community
Be well!
