you can just press 'edit' in your post and add paragraphs now, no need to recopy it...
when you say 'strongest hallucinogen', it is not true, plenty of other substances are active at smaller doses like acid, salvia, 5-meo-dmt, etc... Also I would argue that using the word 'hallucinogen' is a bad choice.
then you got "This may sound like the work of a science fiction movie but Dimethyltrypatime" <--- spelling mistake.
as people said, the referencing is very very poor. Are you familiar with how referencing works in the academic world, btw? In any case, wikipedia is not a good source, neither is joe rogan. You should look for scientific peer-reviewed articles instead to give you more credibility and accurate information, for example dig through this thread:
Scientific Articles on DMT/Ayahuasca/Psychedelics - DMT Discussion - Welcome to the DMT-Nexus
There are factual innacuracies like for example saying dmt is produced when we sleep. Also, DMT is a 5-ht2 AGONIST not antagonist... And other examples out there.
The tone of the essay is not formal enough (the general tone, using expressions like that the substance 'kicks in', using trip reports with a lot of cursing, etc). You said it was a joke of a class, and then you use this as a reason to not write a good enough essay? What are you trying to accomplish here, with this essay? Is it just the fulfilling of a school task you dont care about, and that you dont make enough effort? If so, then why are you posting here (im asking this for you to think, dont be offended)? Wouldnt it be better to instead, write an awesome essay and show them what real drug education/information should be like? If I was a 'straight' teacher I would probably not react well to this essay. Neither am I finding it good from a dmt-interested person.
You talk about how aya can be made from numerous plants, which is not entirely true. Ayahuasca ALWAYS has to be made with caapi, its the admixtures that may change.
I would also question you mentioning extracting dmt including the costs, that might attract very bad attention to you in school.
I think the ending could have been better. When writting essays one should have a basic structure, introduction, development and conclusion. Your conclusion was just a sentence and it beared no connection to what you wrote in the beginning.
There are other things to mention but im sure you get the idea
This was meant as constructive criticism, im sure you can do much better
