DXM:Draft

Romilar 1968 Ad

Dextromethorphan (also known as 'DXM', 'DM' or 'robo') is an over-the-counter antitussive (cough treatment) which when taken at doses exceeding the recommended therapeutic range becomes a powerful dissociative drug which also has some psychedelic properties.

While DXM can be used safely it is not an inherently safe drug. Repeated use within a short period of time, combination with certain types of drugs, certain genetic factors and the prevalence of other active ingredients which become harmful at doses needed for disassociation make for a drug which must be used with caution.

The high is not for everyone; it is said to loosely follow the rule of thirds: one third hates it, one third doesn't care, and one third like it. It should not be underestimated as a hallucinogenic, at higher dosages mimic high doses of ketamine but with more psychedelic properties.

DXM manifests its effects in a series of plateaus, with dose determining which plateau (and subsequently which effects) one will experience. Lower dose plateaus can be well suited to relaxation, light social interaction and listening to music, however higher doses result in a more encompassing dissociative experience which does not lend itself to attentive presence. At high doses it's common to have strong hallucinations, experiences of detachment, depersonalization, and out-of-body experiences. These all-encompassing states are startling and uncomfortable for some.

It's mechanism of action is via multiple effects, including actions as a nonselective serotonin reuptake inhibitor and a sigma-1 receptor agonist. DXM and it's major metabolite, dextrorphan, also act as an NMDA receptor antagonist at high doses, which produces effects similar to, yet distinct from, the dissociative states created by other dissociative anaesthetics such as Ketamine and PCP.

DXM does not typically show up in normal drug tests however it can produce false positive results for PCP and/or Opioids in extended or specialized drug tests. Proper occasional use should not produce these false-positive results after a couple days have passed.

History

The racemic parent compound racemorphan was first described in a Swiss and US patent application from Hoffmann-La Roche in 1946 and 1947, respectively; a patent was granted in 1950. A resolution of the two isomers of racemorphan with tartaric acid was published in 1952, and DXM was successfully tested in 1954 as part of US Navy and CIA-funded research on nonaddictive substitutes for codeine.

The FDA approved DXM in 1958 after research supported its legitimacy and effectiveness as a cough suppressant. After its approval, it was introduced as an OTC medication under the name Romilar, which was introduced as a replacement for codeine containing cough remedies in an effort to cut down on abuse. In early 1960s Beat poets Allen Ginsberg and Peter Orlovsky, musicians such as Daevid Allen Soft Machine, and alternative authors such as Jack Kerouac known to have used DXM in the form of Romilar. In 1973, Romilar was taken off the shelves after a burst in sales because of frequent misuse, and was replaced by cough syrup in an attempt to cut down on abuse. In 1975, the popularity and extensive abuse of DXM was recognized, and Romilar was removed from the OTC market. However, DXM was specifically excluded from the Controlled Substances Act (CSA) of 1970, therefore, it was still legal to produce and use.

A few years after its removal from OTC, companies began introducing refined DXM products (e.g., Robitussin, Vicks-44, Dextrotussion) that were designed to limit recreational use by creating an unpleasant taste if consumed in large quantities. Within a short time those same manufactures began to produce forms of DXM with "some appealing flavoring," which led at least one researcher to suggest that the cycle of recreational abuse may be repeated. In 1996, DXM HBr powder could be purchased in bulk from online retailers, allowing users to avoid consuming DXM in syrup preparations.

Different Forms

DXM is widely available in over-the-counter cough treatments which appear in different forms including gelcaps, lozenges and syrups. DXM is also less commonly found in a more pure powder form, either extracted or bought directly from a chemical manufacturer.

While there are some products available which contain only DXM as active medical ingredients it is common to find products which contain DXM but also contain enough of another active ingredient to pose a serious risk to the user's health.

Extracted

The ideal source of DXM would be an extraction, but that requires time and a chemical procedure which most people are not equipped to do. It's not a complicated process however it does carry some risks in itself. There is a technique known as the 'Agent Lemon extraction'. Page with different extraction methods

Gel Caps

DXM Gelcaps such as Robitussin Gelcaps or other no-name brand products containing only DXM encased in a gelcap are often the preferred source for DXM users. For most users gelcaps which contain only DXM produce a more clear headed high in lower doses. Most users experience fewer side effects from gelcaps than from syrup however some users report an upset stomach from the gelcaps, indicating that some users may have a sensitivity to the edible plastics used to make the gelcaps.

Lozenges

There are also sore-throat and cough medications containing DXM which exist in the form of a hard-candy like lozenge. These sometimes contain only DXM, however most brands of DXM lozenges also contain analgesics such as acetaminophen or benzocaine. Some brands such as Cordicin Cough and Cold (also known as CCC) have a variety of products, most of which contain other active ingredients such as antihistamines or CPM (Chlorpheniramine Maleate) and may have one or two products which contain only DXM.

WARNING: Cordicin Cough & Cold is one of the most commonly used sources of DXM, and also one of the most dangerous. Nearly every single CCC product contains other active ingredients such as CPM, which can cause severe and life-threatening symptoms including seizures, shortness of breath or troubled breathing, weakness, loss of consciousness, severe dryness of the mouth, nose or throat, bleeding from the skin, mouth, eyes, rectum and vagina, and possibly death. CCC also is additionally harmful to your kidneys, liver and heart. JUST AVOID IT!

As always when using lozenges always choose a product which only has DXM in it.

Syrup

Cough syrup is the most common source for DXM users. While there are many brand name and no-name syrups which only contain DXM as an active ingredient there are many active and "inactive" ingredients commonly found in cough syrups which can cause negative effects ranging in severity. See Harm Reduction for more information.

Some say the high produced from syrup is mostly sedating. You may feel sluggish when using it to get high on DXM, possibly as a result of other ingredients found in syrup however because of the even dispersion of DXM throughout the syrup it is said to produce a more 'solid' trip.

Delsym

Delsym is brand with many formulations which contain Dextromethorphan Polistrex.

This is an extended release form of DXM which produced a longer lasting trip with weaker effects. It is somewhat more difficult to reach the third plateau using polistrex preparations which may be preferable for this reason to beginners or users who would prefer a longer and weaker trip. See Dosage information below

Dosage

The dosage below refers to an "average" 180lbs / 80kg person taking DXM HBR. Before dosing it's important to note a few things:

• HBR and Polistirex doses vary significantly due to polistirex slow absorbsion rate. Dextromethorphan Polistrex has a slightly different dose range, but it's fairly easy to understand. Consider the effective mg to be roughly 50-75% of the effect over roughly 1.5-2x the length of the high and glow.

• DXM doses are affected by weight. For more accurate dosage information, see the following resources:

• For a graphical chart of the dosage ranges this chart is helpful.

• For an easy calculator that does the math for you, this page can be helpful.

Before dosing, be sure to read the Plateaus section to know which level you want to dose for.

Plateau range dosage for a 80kg (180lb) person.

First	122-200mg
Second	200-600mg
Third	600-1200mg
Fourth	1200-1600mg
Risk of death	2.2g+

Duration

Oral HBR

Total

6-8 hours of the actual high, with an afterglow effect of 8-16 hours, depending on dose

Oral Polistirex

Total

8-12 hours with an afterglow effect of 16-36 hours, depending on dose

Redosing

Redosing is not advised. (because risk of sigma? make reference to *see sigma*)

It's better to know how much you've taken at the start of the trip, rather than guesstimate how much you're on as you keep dosing. The effects will start to come in waves and may not be pleasant. If you feel the need, it's recommended to take a high initial dose and a lower dose 1-2 hours in.

Predosing

Grapefruit juice can potentiate dxm 30-50% additionally due to interactions with cytochrome P450-2D6.

In order to properly predose, drink at least 16oz (500mL) 2 hours prior to the point where you dose the dxm itself.

Effects

As previously stated, the effects of this drug vary wildly from plateau to plateau, this list is in general from ALL plateaus.

Positive

• Euphoria, mood lift

• Increased giggling and laughing

• Dissociation of mind from body (positive when sought)

• Creative dream-like experiences

• Increased tactile sensation

• Some users report empathy and forgiveness towards other people

Neutral

• Pupil dilation

• Visual stop motion effect (flanging or strobing)

• Visual and aural (auditory) hallucinations

• Decreased sexual functioning (difficulty achieving orgasm)

• Confusion, disorientation

• Skin sensitivity, alters tactile (touch) and skin sensations

• Robotic, zombie-like walking, "robo-walk"

• Dis-coordination, reduced agility

• Loss of appetite

• Involuntary flexing of muscles

• Feelings of merging with adjacent objects like a couch or bed (with higher doses)

• Some users report feeling disconnected, isolated from others, (positive when sought)

Negative

• Vomiting

• Dizziness

• Body itching

• Rash, red blotchy skin

• Diarrhea

• Fever

• Tachycardia (racing, pounding heart)

After-Effects

The after-effects of DXM are referred to as the afterglow.

The afterglow is almost non-existent on the First Plateau.

For a Second Plateau dose, the afterglow can be quite pleasurable, although some feel depressed/hungover afterwards for up to 14-16 hours after the initial dose.

For a Third Plateau dose, the afterglow may additionally add a headache, feel more like an alcohol hangover, and almost like a 1st plateau trip for most of the day after. The effects of this may last for up to 16-20 hours

For a Fourth Plateau dose, don't plan anything for the day after, because you will be very "out of it" for a good 24-32 hours after dosing. Definitely plan a Fourth Plateau dose at least a good 2 days away from social events, work, school, ect. (IE, do it Friday night/Saturday Morning if you have to work Monday). Eating becomes a difficult task during a Fourth Plateau afterglow. The best things to eat during this period are soft foods like yogurt, mashed potatoes, soups, and nutritional milkshakes like SlimFast or ENU Total Nutrition Meal Replacement Shakes. This afterglow may be fairly painful like an alcohol hangover. You will also appear to be very very very high from an outward appearance.

Robo-Walk

The robo-walk feels like all of the muscles in your body are activated at once and while strange to the observer is not painful to the individual. You can still walk but detailed coordination such as running, jumping, or maneuvering around furniture becomes much harder if not impossible. However, when you you start getting the effects of robo-walk, you really wouldn't want to be moving around anyway. The best thing to do is get a good pair of headphones, turn off the lights, close your eyes and let your mind wander.

It's similar to being overly aware that you are walking incorrectly and overcompensating because of it. Not much you can do about it except to minimize your walking by having everything ready before you start(food, water, triptoys, grapefruit juice, dxm in whatever preparation, ect).

Plateaus

There are various 'stages' to DXM trips called plateaus. Traditionally, there are only four plateaus that someone should try to aim for. All of them share general feelings of dissociation, but the strength and effects of these feelings are more pronounced in the later two plateaus.

There are two plateaus are commonly associated with a mix of being high on THC and drunk on alcohol. If you take a first plateau dose, it's totally possible to socialize. At second, it becomes harder, but not impossible. Lower plateau doses are relatively easy to hide compared to higher plateau doses and talking with others becomes a lot easier while under the influence of DXM. It would also be fun to chill in your room alone and do whatever you normally do for fun, but it's suggested to try something that will take up most of your attention but allow your mind to wander at the same time. Something like playing a casual video game, or drawing whatever comes to mind.

If you take a third or fourth plateau dose, it's recommend to trip alone or with a close friend, as it's not a social drug at this dose. The best way to enjoy it is to lay back and listen to music with your eyes closed.

Choosing your destination plateau will depend a lot on what other drugs you've done and how comfortable you are with your own mind. People who have never tried any hallucinogen other than marijuana and/or alcohol should start at First Plateau, while people with mushrooms or LSD experience could start at Second. It is not advised to start at the third or fourth unless you have extensive experience with other dissociatives.

First Plateau

The first plateau is the lightest in effect. It feels a bit 'off', and is often likened to something of a cross between the effects of MDA and Alcohol. First plateau is usually slightly stimulating. The First plateau has also been described as "basically like a hit or two of good weed and 2-3 beers with 10 minutes of a 'trip' about 2 hours in."

Effects commonly experienced at the first plateau level

• A shift in thinking perspective; things look and feel 'different'

• Increased tactile sensation

• Increased appreciation of music

• Feeling heavy, sensation of increased body weight

• Enhanced emotional response & sensitivity

• Some dizziness or vertigo

First Plateau dose: 1.5-2.5mg/kg.

Second Plateau

This plateau is a bit more intense. You may feel like you are stoned and movement may become difficult. The second plateau can be fun yet disorienting. Music sounds much deeper, clearer, almost like you are there at the concert. Walking/Moving your body becomes slightly difficult at this point. Some may experience some closed eye visuals at this point. You can socialize with close friends and you could say you're slightly drunk. A slight warning, DXM is almost like a truth serum and you may share embarrassing or "secret" things you wouldn't normally share. You may start to get a bit of disassociation, and the high starts to get somewhat intense in the second plateau.

Second Plateau dose: 2.5-7.5mg/kg.

Transitional

Most people stop their DXM journey here, as the higher two plateaus are not really fun but introspective and enlightening. We don't recommend crossing this threshold until you're ready to move on from a lighter, happier experience to a sometimes darker and definitely more introspective full blown trip. Enjoy the 2nd plateau as long as you can because it's more of a fun experience and one tends to enjoy second plateau less after visiting the third plateau. "Once you see what's behind the curtain, you can't enjoy the show" so they say.

Additionally, exactly at 7.5mg/kg there is an elusive "Eiffel Tower" dose where you experience the effects of both the second and third plateaus simultaneously.

Third Plateau

Third plateau is a full on dissociative experience. You cannot ignore the feeling inside of you and at this point its no longer a social drug and should be done by yourself or with a sitter. The third plateau isn't 'party-mode' or even 'socialize-mode'. Its more like 'alone-and-tripping-mode'. Closed eye visuals are more prominent at this level. You will lose track of time quit easily as it becomes meaningless quite quickly. Large amounts of dissociation happens at this level, and the internal thoughts can be quite interesting. To explain further, you may start to feel like you don't belong in your own body, or that your mind and body are two seperate beings. Additionally, thoughts may be similar to "My body is only what everyone else sees but not really me, because I am just my mind, not my body."

Third Plateau dose: 7.5-15 mg/kg.

Fourth Plateau

This is the deep meditative state. This is most akin to a "k-hole" that people experience after taking large amounts of ketamine. Few people enjoy going this far, as all one can really do (or really wants to do) is sit, listen to music, close your eyes, and experience a full blown dissociative trip. You can create universes in your mind just by thinking of them. DXM users have been known to have extremely vivid, controllable hallucinations and out of body experiences at this level. Full blown disassociation from everything and full on ego death is very common at this level. Other very common hallucinations at this level are people visiting aliens, meeting god (sometimes the two being the same entity) and becoming god. One explanation of the fourth plateau "It's kind of like the top of your skull pops off and all the knowledge of the universe is poured into your head, but by the end of the trip it's all seeped out again and you are left with the realization that you really don't much of anything at all."

It is quite difficult to recall these very powerful hallucinations as post-trip amnesia is very common.

Fourth Plateau dose: 15mg/kg and higher.

Plateau Sigma

There is another level that DXM can take you to, but it is not higher in dosage than 4th plateau, it is more of an extension of 2nd and 3rd plateaus. In order to get to this state, you must binge. For this reason WE HIGHLY RECCOMEND AGAINST IT! For example, a user has said "I took a 3rd plateau dose, then when it was starting to wear off, I took a 2nd plateau dose, when that was finally coming down, I took a 3rd plateau dose again, and when that came down, I did ANOTHER 2nd plateau dose. When that final dose hit, I was stuck in Plateau Sigma."

Many people refer to this level as "plateau sigma" because when you get to this state, your sigma receptors are hit on, and HARD. This completely changes the trip. This mind state is generally referred to as dysphoric, dark, confusing and "a hellish introspective nightmare". As one user put it "it's a dark and confusing dream-like state where everything you think you know is insanely hard to grasp while all of your wildest, most bizarre fantasies are merely common, boring every day events that feel as normal as waking up and drinking coffee."

As with 4th plateau, it's hard to describe as amnesia is quite common and information about this state is quite rare as it is. That being said, this state has NEVER been reported as being pleasurable AT ALL. Most people describe it as dark and confusing, like a living nightmare.

Harm Reduction

See Dissociative Harm Reduction for general information.

Adulteration

Many products which contain DXM also contain other medication or otherwise non-medically-active ingredients that can cause serious harm in the doses found in DXM containing products. If a user intends to use an OTC cough medication in order to get high on DXM they almost always will have to consume a dangerous quantity of other dangerous ingredients if they are present in the medication. For this reason it is strongly recommended to find a source which contains ONLY DXM.

The following is a summary of other ingredients commonly found in DXM products.

Adulterant Table

Name	Description	Common Brands	Danger
Acetaminophen/Paracetamol/APAP	a painkiller found in headache/flu medicine	Tylenol, Vicks (NyQuil), TheraFlu, Triaminic	is hepatoxic in high doses. This means it will damage your liver if taken in high doses. Your body can only process a certain amount of APAP at once before it the normal pathways become saturated Once the regular pathways used for metabolizing APAP have been saturated the remaining APAP gets broken down in the liver by an enzyme called cytochrome P450 When forced to break down APAP this enzyme produces toxic metabolites!
Guaifenesin	Guaifenesin is an expectorant.	Robitussin DM, Mucinex, Robefen	Guaifenesin overdoses cause severe nausea and vomiting in most users.
Antihistamines	Found in Allergy/Sleep/Nighttime medications	Coricidin Cough and Cold, Zicam, Dimetapp, Chloraseptic	When taken in high doses antihistamines can cause dizzyness, nausea, a strong dysphoria, paranoia, delirium and hallucinations. Many antihistamines can also have a dangerous synergy with DXM

• Food Coloring & other "Inactive" Ingredients

Many DXM products contain dyes which can cause allergic reactions in some users. Usually these dyes are not harmful in low doses however in doses which may be

required for DXM's effects they can become problematic. Tartrazine (FD&C Yellow #5) is one of the most notable coloring ingredients to cause reactions.

Cough syrups usually contain one or more chemical used to make them taste sweet.

Glucose, sucrose, invert sugar, and fructose are commonly used sweetening agents. These sweeteners pose an obvious risk to people with blood sugar conditions

such as diabetes or hypoglycemia.

Thickening agents such as propylene glycol or polyethylene glycol are found in most cough syrups. These are not toxic but may cause an upset stomach

when consumed in large doses.

Interactions

DXM has several potentially dangerous interactions with pharmaceutical and recreational drugs including analgesics (painkillers), antihistamines, antidepressants and stimulants.

DXM has the potential to cause Serotonin Syndrome if mixed with other serotonergic drugs such as antidepressants that act as SSRIs, MAOIs, empathogens which affect serotonin release such as MDMA, MDA, Mephedrone, etc. Serotonin Syndrome causes discomfort, excitability, irritability, diarrhea, moodswings, seizures, coma and can be deadly if not treated.

Pharmacokinectics

Following oral dosing, DXM is rapidly absorbed from the GI tract. Where it enters the bloodstream, and crosses the blood-brain barrier.

At therapeutic doses, DXM acts centrally (brain) as opposed to locally (Respiratory tract). It's rapidly absorbed from the GI tract into the active metabolite Dextrophan (DXO) in the liver by the cytochrome P450 enzyme CYP2D6.

Around 10 percent of the Caucasian population has little or no CYP2D6 enzyme activity, leading to long-lived high drug levels. ALL Caucasians should take a small test dose (1st plateau or medical levels) to feel for this ahead of time.
