Don't try and extract dmt under your parents roof, it puts them in legal jeopardy if anything went south, and may cause you to lose their trust and/or get kicked out on the street depending on what kind of people they are.
All of the questions you ask can be answered by searching, but since your not an adult yet i can only recommend researching about dmt/psychadelics if your really interested in them.

Remember your brain is still in heavy development, and that process is best left to its own devices.
