DMT

This documentary is pretty eye opening. Not only does it highlight the features of DMT, an organic compound found in plants, animals and humans, but also makes you realize how ass backwards North American laws are. DMT is a natural drug and opens the mind up into a dream like state. To be honest it's extremely safe, in the idea that it doesn't harm the body because our bodies already make DMT. But apparently this drug can lead to life changing experiences. This documentary looks at a study that explored the effects of the drug, physically, but also the subjective experience. Most of the subjects are professionals, like psychologists, neuroscientists, writers and mathematicians. Even if you aren't into the whole drug experimentation, this documentary isn't merely about doing drugs, but also spirituality.
