N,N-Dipropyltryptamine (DPT, also known as "The Light") is a psychedelic drug belonging to the tryptamine family, first reported in 1973. DPT is an intense synthetic hallucinogenic drug. DPT is the primary sacrament for "Temple of the True Inner Light" a Christian off shoot organization that believes in psychedelics and primarily DPT as the true flesh of God.
{{SubstanceBox/DPT}}
'''N,N-Dipropyltryptamine''' (also known as '''Dipropyltryptamine''', '''DPT''',  and '''"The Light"''') is a lesser-known [[psychoactive class::psychedelic]] substance of the [[chemical class::tryptamine]] class. It is closely related to [[DMT]] and is reported to be uniquely similar in its hallucinogenic intensity, albeit with a moderately longer duration and greater unpredictability relative to DMT and other psychedelic tryptamines.  


DPT is most commonly consumed via [[Routes of administration|insuffalation or intramuscular injection]]. Some report the experience of insuffalation being very painful, which with the rapidness of onset, does not give the user much time to acclimate themselves to the effects as they come on strongly.
DPT was first synthesized in 1950.<ref>{{cite journal|last1=Li|first1=J. X.|last2=Rice|first2=K.|last3=France|first3=C.

DPT is commonly consumed via [[insufflation]] or [[orally]]. Many report the experience of insufflation to be very congestive and painful which, with the rapidness of onset, does not give the user much time to acclimate themselves to its powerful effects. It can also be administered [[intramuscular|intramuscularly]] or via [[vaporization]] after conversion to the freebase form. Smoking the freebase is reported to be the preferred route used by the "Temple of True Inner Light". More experienced members ingest a DPT tea. {{citation needed}}
 
Very little data exists about the pharmacological properties, metabolism, and toxicity of DPT, and it has relatively little history of human usage. It has long been available on the [[research chemicals]] market as a legal, grey-market alternative to [[DMT]], and commercially distributed through online vendors. Many reports also suggest that this substance may be overly difficult to use safely for those who are not already very experienced with [[hallucinogens]]. It is highly advised to approach this powerful [[psychedelic]] substance with the proper amount of precaution and [[Responsible drug use#Hallucinogens|harm reduction practices]] when using it.

[[File:SubstitutedTryptamine.png|thumb|294px|right|General formula of a tryptamine molecule.]]
DPT, or N,N-dipropyltryptamine, is a synthetic indole molecule of the [[tryptamine]] class. Tryptamines share a core structure comprised of a bicyclic indole heterocycle attached at R<sub>3</sub> to an amino group via an ethyl side chain. DPT contains two propyl groups carbon chains bound to the terminal amine R<sub>N</sub> of its tryptamine backbone.  
 
DPT has a number of substituted analogs such as [[4-HO-DPT]] or [[4-AcO-DPT]].
 
==Pharmacology==
==Pharmacology==
{{Main|Serotonergic psychedelic}}
{{pharmacology}}
DPT's [[psychedelic]] effects are believed to come from its efficacy at the [[Serotonin#The 5-HT System|5-HT<sub>2A</sub> receptor]] as a [[Agonist#Agonists|partial agonist]]. However, the role of these interactions and how they result in the [[psychedelic]] experience continues to remain elusive.
{{Further|Serotonergic psychedelic}}
Studies on rodents have found that the effectiveness with which a selective 5-HT<sub>2A</sub> receptor antagonist blocks the behavioral actions of this compound strongly suggest that the 5-HT<sub>2A</sub> receptor is an important site of action for DPT, but the modulatory actions of a 5-HT<sub>1A</sub> receptor antagonist also imply a 5-HT<sub>1A</sub>-mediated component to the actions of DPT.<ref>{{cite journal | vauthors=((Fantegrossi, W.)), ((Reissig, C.)), ((Katz, E.)), ((Yarosh, H.)), ((Rice, K.)), ((Winter, J.)) | journal=Pharmacology Biochemistry and Behavior | title=Hallucinogen-like effects of N,N-dipropyltryptamine (DPT): Possible mediation by serotonin 5-HT1A and 5-HT2A receptors in rodents | volume=88 | issue=3 | pages=358–365 | date= January 2008 | url=https://linkinghub.elsevier.com/retrieve/pii/S0091305707002894 | issn=00913057 | doi=10.1016/j.pbb.2007.09.007}}</ref> The role of these interactions and how they result in the [[psychedelic]] experience remains the subject of ongoing scientific investigation.


==Subjective effects==
==Subjective effects==
The effects listed below are based upon the [[subjective effects index]] and personal experiences of [[PsychonautWiki]] [[PsychonautWiki#Contributors|contributors]]. The listed effects will rarely if ever occur all at once but heavier dosages will increase the chances and are more likely to induce a full range of effects.
Relative to psychedelic tryptamines like DMT, DPT is often reported to be similar in its [[hallucinogenic]] intensity, albeit with a moderately longer duration and more challenging effects. DPT experiences are often described as a "bizarre", "unsettling", and "darker" version of DMT experiences. DPT is reported to be more sensual and physical than DMT and other psychedelics with a corresponding amount of adverse physical effects.  
===Physical effects===
 
The physical effects of DPT can often be jarring. At light to moderate doses there is often a slight sense of anesthetization and relaxation. As the dose increases, perceptions of heart rate increase, body tremors, and loss of muscle control are often reported.
At light to moderate doses, users often report a slight sense of anaesthetization and relaxation. As the dose increases, hyper-awareness of one's heart rate and breathing increases and body tremors and loss of muscle control are often reported. The effects of DPT can range from strong euphoria and sensuality to nausea, panic, and intense states dysphoria even within the same experience.
 
{{Preamble/SubjectiveEffects}}
{{effects/base


*'''[[Physical effects: Spontaneous tactile sensations|Spontaneous tactile sensations]]''' -The body trip of DPT is generally more prominent of that of the better known DMT. There is often the sensation of limbs feeling disconnected from the body, a force pinning the body to the surface on which itlay and body tremors which can often make the user feel aware of but not in control of their body.

*'''[[Effect::Pattern recognition enhancement]]'''
*'''[[Effect::Magnification]]'''


*'''[[Physical effects: Changes in gravity|Changes in gravity]]''' - At higher dosages, physical feelings of moving through spaces at quick speeds or being pinned down are common.

===Cognitive effects===
====[[Effect::Geometry]]====
DPT tends to make the user feel slightly anesthetized but, unlike [[dissociatives]], still aware. At low to moderate doses, much of the cognitive effects are not too dissimilar from [[LSD]] or [[mushrooms]]. At higher does, the mind tends to pull personal experiences into abstract phenomenal worlds, or bizarre hallucinatory and/or spiritual images to what the mind gravitates to. Most of the cognitive assimilation of the DPT trip comes on during the latter half of the trip as in the first half the mind is usually overwhelmed by the sensorium that comes across the mind.
DPT visual geometry can be described through its variations as intricate in complexity, both abstract and concrete in form, more digital than organic in feel, choppy and only loosely structured in organization, brightly lit, multicolored in scheme, sharp in its edges, fast in speed, simultaneously smooth and glitching in motion, immersive in depth, and consistent in intensity. At higher doses, it is more likely to result in states of [[Effect::8A Geometry|level 8A geometry]] over level 8B.  


*'''[[Cognitive effects: Enhancement of current mind state|Enhancement of current mind state]]'''
====Hallucinatory states====
*'''[[Cognitive effects: Removal of cultural filter|Removal of cultural filter]]'''
DPT produces a full range of high level hallucinatory states in a fashion that is more consistent and reproducible than that of any other commonly used psychedelic barring [[DMT]] and [[ibogaine]]. These effects include:
*'''[[Cognitive effects: Feelings of fascination, importance and awe|Feelings of fascination, importance and awe]]'''
*'''[[Cognitive effects: Rejuvenation|Rejuvination]]'''
*'''[[Cognitive effects: Direct communication with the subconscious|Direct communication with the subconscious]]'''
*'''[[Cognitive effects: Ego suppression, loss and death|Ego suppression, loss and death]]'''
*'''[[Cognitive effects: States of unity and interconnectedness|States of unity and interconnectedness]]'''


===Visual effects===
*'''[[Effect::Transformations]]'''
At lower to moderate doses, DPT visuals tend to resemble more of an [[LSD]] trip, however as the dose increases, DPT visuals can approach that of [[DMT]] in complexity and structure.
*'''[[Effect::Machinescapes]]''' - These are reported to be more common with [[DPT]] than with [[DMT]], which lends to its common description as feeling more "industrial" and futuristic, while [[DMT]] visuals can often be described as "ancient" or "earthy" in feel.
*'''[[Effect::Internal hallucination]]''' (''[[effect::autonomous entities]]''; ''[[effect::settings, sceneries, and landscapes]]''; ''[[effect::perspective hallucinations]]'' and ''[[effect::scenarios and plots]]'') - As with [[DMT]], DPT produces high level internal hallucinations at appropriate doses more consistently than most other [[psychedelics]]. They are more common within dark environments and can be comprehensively described through their [[Internal_hallucinations#Variations|variations]] as lucid in believability, interactive in style, new experiences in content, non-autonomous in controllability, geometry-based in style and almost exclusively of a personal, religious, spiritual, science-fiction, fantasy, surreal, nonsensical or transcendental narrative in their overall theme, with a tendency towards chaotic disorganization and incoherence.
*'''[[Effect::External hallucination]]''' (''[[effect::autonomous entities]]''; ''[[effect::settings, sceneries, and landscapes]]''; ''[[effect::perspective hallucinations]]'' and ''[[effect::scenarios and plots]]'') - These are more common within dark environments and can be comprehensively described through their [[External_hallucinations#Variations|variations]] as lucid in believability, interactive in style, new experiences in content, non-autonomous in controllability, geometry-based in style and typically of a personal, religious, spiritual, science-fiction, fantasy, surreal, nonsensical or transcendental narrative in their overall theme, with a tendency towards chaotic disorganization and incoherence.


Many visuals between DPT and DMT are similar in quality and complexity but with DPT the visuals often tend to take on a more sinister tone. The anesthetized quality DPT elicits often makes the visuals appear more surreal and less 'real' then DMT visuals, however the experience can also be more disorienting due to this factor.
}}
|{{effects/cognitive|


The visuals of a high dose DPT trip have the refined visual sheen, structure and gloss of being seemingly 'more real than reality.' Patterns often replicate into spiraling patterns that are fractal in structure and go on as far as the field of vision can see, often giving way to new sets of patterns. Sometimes the visuals on DPT are more pronounced then others, yet on less intricate visuals trips there is often a sense of being thrust into and through and all-encompassing void where sense of direction is significantly altered, often causing the sensations of floating or falling.
*'''[[Effect::Anxiety]]''' & '''[[Effect::Paranoia]]'''
*'''[[Effect::Conceptual thinking]]'''
*'''[[Effect::Cognitive euphoria]]''' & '''[[Effect::Cognitive dysphoria]]'''
*'''[[Effect::Déjà vu]]'''
*'''[[Effect::Emotionality enhancement]]'''
*'''[[Effect::Feelings of impending doom]]'''
**'''[[Effect::Catharsis]]'''
**'''[[Effect::Rejuvenation]]'''
*'''[[Effect::Increased music appreciation]]'''

*'''[[Effect::Wakefulness]]'''


The hallucinatory phenomena of DPT can range from distortions of objects within a room to complex entities such as deities, bats, entities, orbs, etc. which often replicate themselves in a fractal manner or transform into some other form in the mind's eye. Unlike DMT, where  visuals often seem like they practically could be composed no other way, DPT visuals are often less deterministic and there is often a sense of 'scene changes' where the quality and complexity of the scene can transfer to something completely different. Daniel Pinchbeck, author of ''Breaking Open the Head'' <ref> Breaking Open the Head By Daniel Pinchbeck </ref> comments on the entities of DPT that "They often appear as if they want to be admired. At other times there seemed to be bat or butterfly-winged creatures long and quivering antennaes, velvet coats and emerald eyes, stiletto talonsrising into otherworldly skies, wandering futuristic cities. I had an impression of tremendous vanity. I was being used as a mirror for the DPT beings to admire themselves."

{{effects/multisensory|
*'''[[Effect::Synaesthesia]]''' - In its fullest manifestation, this is a very rare and non-reproducible effect. Increasing the dosage can increase the likelihood of this occurring, but seems to only be a prominent part of the experience among those who are already predisposed to synaesthetic states.


*'''[[Visual effects: Increased visual acuity|Increased visual acuity]]'''
}}
*'''[[Visual effects: Enhancement of colour|Enhancement of colour]]'''
{{effects/transpersonal|
*'''[[Visual effects: Enhanced pattern recognition|Enhanced pattern recognition]]'''
Many reports indicate that while [[DPT]] possesses the raw [[hallucinogenic]] power to induce transpersonal states traditionally associated with "classical psychedelics", it does so in a significantly less consistent fashion due to the utter bizarreness and oft-noted "sinister", chaotic, or "forceful" undertones that can be present throughout the experience. What insights it can lead the user to typically occur during the aftermath and integration phase that follows, which shares some qualities of a typical near-death experience.

*'''[[Effect::Perception of predeterminism]]'''
*'''[[Effect::Perception of eternalism]]'''
*'''[[Effect::Perceived exposure to inner mechanics of consciousness]]'''
*'''[[Effect::Unity and interconnectedness]]'''


=====Taking off=====
}}
The first step of a DPT trip is the come up that leads onto breaking through. This is something that seems to have at least a few different ways of presenting itself to the user as they start to snort or inject DPT.

=====The other side=====
==Toxicity and harm potential==
{{toxicity}}
{{further|Research chemicals#Toxicity and harm potential|Responsible use #Hallucinogens}}
The toxicity and long-term health effects of recreational DPT do not seem to have been studied in any scientific context and the exact [[Toxicity::toxic dose is unknown]]. This is because DPT is a [[research chemical]] with very little history of human usage. There has been one death associated with the use DPT and seizures, but the dose is unknown.<ref>{{Citation | vauthors=((Tribune, B. D. S.)) | title=Carver County teen’s death puts spotlight on ease of purchasing synthetic drugs online | url=https://www.startribune.com/carver-county-teen-s-death-puts-spotlight-on-ease-of-purchasing-synthetic-drugs-online/330344661/}}</ref>


=====Coming down=====
Anecdotal reports from those who have taken DPT suggests that negative health effects are not likely to occur from simply trying it by itself at low to moderate doses and using it sparingly (although nothing can be guaranteed). [https://www.google.com/ Independent research] should always be done to ensure that a combination of two or more substances is safe before consumption.
The final stage is experienced as the sensation of being pulled further and further away from the scenario in which one was placed as the entities often wave goodbye and encourage one to come back when you next get the chance.


==Toxicity and Harm Potential==
It is strongly recommended that one use [[responsible drug use|harm reduction practices]] when using this substance.
DPT is not known to cause brain damage, and has extremely low toxicity relative to dose. However via intramuscular injection there has been reports of an individual passing out at 130 mgs.<ref> A DPT Primer by Toad | https://www.erowid.org/chemicals/dpt/dpt_primer.shtml#dose </ref>
 
===Tolerance and addiction potential===
DPT is [[Addiction potential::not habit-forming]] and the desire to use it can actually decrease with use. As with most psychedelics, it is reported to be self-limiting.
 
Tolerance to the effects of DPT has been shown to not be built in animal models.<ref>{{cite journal|last1=Smith|first1=D. A.|last2=Bailey|first2=J. M.|last3=Williams|first3=D.|last4=Fantegrossi|first4=W.

===Dangerous interactions===
{{DangerousInteractions/Intro}}
 
*'''[[Tramadol]]''' - Tramadol lowers the seizure threshold<ref>{{cite journal|last1=Talaie|first1=H.|last2=Panahandeh|first2=R.|last3=Fayaznouri|first3=M.

*'''[[Stimulants]]''' - Stimulants affect many parts of the brain. Combined with psychedelics, stimulation can turn into uncontrollable [[anxiety]], [[Panic attacks|panic]], [[thought loops]] and [[paranoia]]. This interaction may cause elevated risk of psychosis.{{citation needed}}
*'''[https://en.wikipedia.org/wiki/Lithium_(medication) Lithium]''' - Lithium is often used as treatment for bipolar disorder. It may possibly cause elevated risk of seizures and psychosis due to its [[Glutamate|glutaminergic]] and [[GABA|GABAergic]] effects.{{citation needed}}
