good question
terrence mckenna was on shrooms, acid and smoked weed
carl sagan smoked cannabis as well
research the PINEAL GLAND/// HYPOTHALMUS
MARIJUANA triggers these parts of the brain...
The pineal gland is also sometimes thought of as the third eye, an organ to perceive and be perceived (transmit and receive) on a psychic or higher level of consciousness. Methods of meditation focus on 'opening' the gland (
Krishna Healing...) and it is said that a person who can do this often feels elated and 'at one with the world' post meditation. Some say this is a result of awakening the gland and creating a connection with the greater collective consciousness.
Still centered in your pineal and loving yourself, call the collective consciousness of the planet into your pineal as quickly as possible. What you should feel next is a quiet oneness, with no separation from anything. Let go and move into the experience. Practice this a few times before moving on to the next step.
It could be said that the trance-like state of meditation is due to the production of melatonin by the pineal, resulting in a sleep-like state.
Others suggest this feeling is merely just a separate chemical reaction akin to that experienced when taking MDMA (which increases serotonin production) or DMT. They suggest that the production of these chemicals (serotonin and DMT), which are already made in small doses in the body, is increased through meditation and other activities such as sport.
"Dimethyltryptamine (DMT), also known as N,N-dimethyltryptamine, is a naturally-occurring tryptamine and potent psychedelic drug, found not only in many plants, but also in trace amounts in the human body where its natural function is undetermined. Structurally, it is analogous to the neurotransmitter serotonin and other psychedelic tryptamines such as 5-MeO-DMT and 4-HO-DMT. DMT is created in small amounts by the human body during normal metabolism[1] by the enzyme tryptamine-N-methyltransferase."

It is interesting to note that as a foetus and during birth the Pineal Gland produces small amounts of DMT.
Rick Strassman has done a lot of research and theorising on relations between the Pineal and DMT.
