I've found that,

LSD - Lysergic acid diethylamide C20H25N3O

https://pubchem.ncbi.nlm.nih.gov/compound/Lysergide

Mushrooms - Psilocybin C12H17N2O4P

https://pubchem.ncbi.nlm.nih.gov/compound/Psilocybin

&

Mescaline - C11H17NO3

https://pubchem.ncbi.nlm.nih.gov/compound/4076

All have long and drawn out uncomfortable experiences. The durations of these trips can last between 8-12 hours. This amount of time in the wrong head space can be more damaging than not have taken the drug at all...

These molecules are elementary in compassion to free base DMT - which is similar but different than orally active DMT (mixed with harmala alkaloids).
Dimethyltryptamine c12h16n2

DMT is a 5 minute trip that takes 15 minutes to cool off.

They are not SWIM's personal opinion, though it is good to understand how the government understands these chemicals and what information they put forth.
