Does heaven exist? With well over 100,000 plus recorded and described spiritual experiences collected over 15 years, to base the answer on, science can now categorically say yes. Furthermore, you can see the evidence for free on the website allaboutheaven.org.

This book, which covers Visions and hallucinations, explains what causes them and summarises how many hallucinations have been caused by each event or activity. It also provides specific help with questions people have asked us, such as ‘Is my medication giving me hallucinations?’.

Some science behind the scenes

Serotonin receptor agonists

A serotonin receptor agonist is a compound that activates serotonin receptors, in a manner similar to serotonin.  It includes a large number of legal drugs and an equally large number of illegal drugs.  The class also includes a very large number of pharmaceuticals that found their way to clinical trial, were rejected, were resubmitted for something else, were rejected and so it goes on.  The following is not atypical

“EMD-49,980 is a dopaminergic and serotonergic drug which was originally developed for the treatment of schizophrenia. In clinical trials its antipsychotic efficacy was only modest but it was unexpectedly found to produce antidepressant and anxiolytic effects. As a result, it was further researched for the treatment of depression instead. It has also been investigated as a therapy for Parkinson's disease and prolactinoma” [source Wikipedia]

A few of the drugs that never make it go onto the recreational market to recoup the losses made in investigation.  This is a somewhat worrying trend as many are rejected because of severe reactions – such as hepatoxicity. 

Universities appear to be a primary area for experimentation in new drugs.  They call them ‘novel’, but new will do. 

Purdue University in the USA, for example, appear to have an almost unlimited budget to make and then release new drugs on the market.  Professor Nichols, Chair in Pharmacology at Purdue University has invented well over 250 drugs including TFMFly , BromoDragonFLY, DMBMPP, escaline, LSZ, 6-APB, 2C-I-NBOMe, 2CBCB-NBOMe , 25I-NBMD and other NBOMe variants, several LSD analogues, including ETH-LAD, PRO-LAD, and AL-LAD, all more potent than LSD itself; MDA, 5-methyl-MDA, 4-MTA and MDAI.  A number of compounds included in Shulgin's PIHKAL were actually first synthesized in Nichols's lab. He also ‘improved the synthesis of psilocybin’.  TCB-2 is a hallucinogen, discovered in 2006 by Thomas McLean, working in the lab of Prof. David Nichols at Purdue University where it was named 2C-BCB.  There are so many we have not listed them all below.   None of these drugs has any medicinal value.

25I-NBOH; 25I-NBOMe, 25TFM-NBOMe, 2CBFly-NBOMe and 25B-NBOMe were invented in 2003 by Ralf Heim at the Free University of Berlin, but were subsequently investigated by a team at Purdue University .  25CN-NBOH was invented in 2011 by Martin Hansen at the University of Copenhagen.

Overall we can conclude that it is universities from which all these new [illegal or street] drugs derive if the evidence is anything to go by.
