Within the context of [[psychonaut]]ic or recreational substance usage, it is important to understand dosages and to pay close attention to them with extreme caution. Administering the wrong dosage of a drug can lead to negative experiences such as extreme [[anxiety]], uncomfortable physical side effects, a [[bad trip|bad psychedelic trip]], hospitalization, or (in extreme cases) death. Taking too low of a dose can often make people feel uncomfortable and frustrated.

A threshold dose can be described as one in which users can experience the effect of the substance at an extremely light and subtle manner which could potentially go completely unnoticed. It is distinctly just beyond that of placebo effect, but it can be ignored with minimal effort should the user attempt to direct their focus towards performing other complex and daily tasks.

A light dose can be described as one in which the effects of the substance are somewhat distinct and noticeable but still background and periphery. They remain possible to ignore with varying degrees of success via compensation through increasing the focus one directs towards other things when performing complex or daily tasks.

The effects can be allowed a predominant role or they may be repressed and made secondary to other chosen activities.

==Choosing dosages==
==Choosing dosages==
An extremely important rule when it comes to using substances responsibly is to avoid dosages which one is uncomfortable or unfamiliar with at all costs. An inexperienced user should always be starting at very low dosages with the goal of working their way up in small increments as they feel comfortable doing so. This should be done by slightly increasing the dosage with each separate experience and never taking great leaps into the unknown.

This should be done by slightly increasing the dosage with each separate experience and never taking great leaps into the unknown.


Doing so allows people to get a feel for the substance that they are using in a controlled setting before they dive into deeper states. For pressed pills, one should buy from a reliable source with consistent product and ask questions concerning purity and how many milligrams of a drug is in a certain pill or tab.

This minimizes the risk of an accidental negative experience enormously; although dosage guidelines exist, it is important to remember that everybody reacts differently to every substance depending on their own personal tolerance and neurophysiology.

===Allergy testing===
Some people, especially those with health issues, have adverse reactions to drugs such as allergic reactions, uncomfortable physical or cognitive effects, or over-sensitivity.<ref name="erowid1">Erowid Psychoactive Vaults: Dose | https://www.erowid.org/psychoactives/dose/dose.shtml</ref> The best way to prevent this is to perform an allergy test, which is simply dosing a minuscule amount of the drug (1/4 of a regular dose) and waiting several hours to a few days.
When performing an allergy test, one should note any dangerous side effects including rashes, hives, breathing discomfort, an uncomfortably fast heartbeat, or a burning sensation on one's skin.<ref name="erowid1"></ref> Depending on the severity of symptoms, medical services may be needed.


==Measuring dosages==
==Measuring dosages==
There are various ways in which users can measure their dosages. Eyeballing is a practice which is strongly discouraged for several reasons. The most accurate and safe method to measure one's drugs is to use both a milligram scale and volumetric liquid dosing.  
There are various ways in which users measure their dosages. The most accurate and safe method to measure one's drugs is to use both a [[Dosage#Milligram scales|milligram scale]] and the [[Volumetric liquid dosing|volumetric liquid dosing]] method. This is a far safer route than "eyeballing" one's dosages by approximating the weight of what they are ingesting simply by looking at it and making a rough (but inaccurate) guess.
===Eyeballing===
===Eyeballing===
Eyeballing is not recommended.
Eyeballing is a highly inaccurate method of measuring substances which involves looking at a substance and making a rough guess of the weight. Since there is not much difference between 10mg and 30mg visually, it is highly discouraged.<ref name="erowid4">How big is a milligram? (Ask Erowid) | https://www.erowid.org/ask/ask.php?ID=2282</ref> There are numerous forms of eyeballing methods, including using micro scoops and the graph paper method.
 
"Many people who acquire powdered psychoactives believe that they can "eyeball" doses accurately enough that a scale isn't required. Eyeballing methods take a variety of forms. One example is the "graph paper method", where a known quantity is spread as evenly as possible on graph paper to determine its volume (size). Doses are measured based on how many graph paper squares they cover. The problem with this inaccurate method--and with most eyeballing methods--is that the volume of a measured mass (weight) of material can vary dramatically depending on how dense the material is.


A solid crystal of mescaline exactly 1 cm by 1 cm will weigh significantly more than an equal-sized pile of fluffy powdered mescaline. Likewise, two exactly equal-sized piles of mescaline can include parts with very different densities. Powders can go from "fluffy", with low density, large crystals, to "cakey", to dense crystals more like table salt. While the difference between powder and a solid crystal would be apparent to the careful eye, the difference between two slightly different densities of powder might not be. Obviously, these problems are even worse when comparing two different substances.
*'''Measuring scoops'''
*'''Graph paper method''' - In this method, a known quantity of a substance is spread evenly onto a piece of graph paper and one's doses are based on how many graph paper squares are covered. This method is inaccurate simply because the volume of a measured weight of powder can vary significantly in its density, even with different batches of the same substance.<ref name="erowid2">The Importance of Measured Doses by Fire Erowid & Spoon | https://www.erowid.org/psychoactives/basics/basics_measuring1.shtml</ref> For example, two equal-sized piles of [[mescaline]] can have completely different densities and therefore different weights.  


Another issue arises when eyeballing methods depend on starting with a known quantity of material. One common process is to take a known quantity of powder, say one gram of MDMA, and divide it into ten equal piles, theoretically resulting in ten 100 mg doses. But if the original "one gram" measurement can't be verified, any dividing process is merely guesswork. While it might seem unlikely that someone selling MDMA will accidentally provide too much material, it's not at all unheard of. We have received many reports from individuals who have ordered a research chemical online only to discover, when the material arrives, that the company sent nearly twice what was ordered.
Users should not trust a vendor's word that their product weighs a certain amount as it is not unheard of for vendors to accidentally or intentionally give out the wrong amount of a product, resulting in overdoses for some users.<ref name="erowid2"></ref>


Substances that have very low dosages, such as 5-MeO-DMT or 5-MeO-AMT, are especially dangerous to eyeball. Basing a "5 mg dose" on the fluffy crystal from last spring could easily lead to a 10 mg overdose of a new denser powder." - Erowid
It is especially dangerous to eyeball substances that have extremely low doses (under 10mg).

The term dosage refers to the size of a dose of a medicine or drug. In regards to the classification of dosage and their amounts, it can be broken down into microdose, threshold, light, common, strong, heavy, and overdose. Each of these levels result in a different intensification of the compound's desired effects depending on the substance consumed.

Within the context of psychonautic or recreational substance usage, it is important to understand dosages and to pay close attention to them with extreme caution. Administering the wrong dosage of a drug can lead to negative experiences such as extreme anxiety, uncomfortable physical side effects, a bad psychedelic trip, hospitalization, or (in extreme cases) death. Taking too low of a dose can often make people feel uncomfortable and frustrated.

Classification

Although different substances induce different effects regardless of their appropriate dosage, the intensity of the experience they are likely to induce can be broken down into five separate categories.

Microdose

A microdose is a sub-perceptual dose which is so low (such as 10 micrograms of LSD) that it is unlikely to produce whole body effects. Microdosing is sometimes used among athletes, claiming improved stamina and abilities in reaction time, balance, perception, and concentration.

Threshold

A threshold dose will cause users to experience the effects of the substance in an extremely light and subtle manner which can potentially go completely unnoticed. It is distinctly just beyond that of placebo effect, but can be ignored with minimal effort when one directs their focus towards performing other complex tasks.

Light

A light dose will cause effects which are somewhat distinct and noticeable but still in the background. The effects remain possible to ignore by increasing the focus one directs towards other things when performing complex tasks.

Common

At this point, not only are the effects and the nature of a drug's action quite clear and distinct, but ignoring its action becomes difficult (although possible to varying degrees through consciously focusing on the task at hand). The user will still have some choice as to whether they will accept the experience, or rather just continue with the day's ordinary plans (if you are an experienced user, that is). The effects can be allowed a predominant role or they may be repressed and made secondary to other chosen activities.

Strong

A strong dose can be described as that which renders its subject as mostly incapable of functioning normally. Not only is the chronology and the nature of a drug's action quite clear, but ignoring its action is no longer an option. The subject is totally engaged in the experience regardless of the external situation.

Heavy

At heavy doses, the user has been rendered completely incapable of functioning on any basic level. Depending on the substance consumed, this will usually result in states of safe catatonia or extremely uncomfortable side effects.

Overdose

An overdose describes the ingestion of a substance in quantities greater than are recommended or generally practiced. An overdose may result in a toxic state or death.

Choosing dosages

It is important that one avoid dosages which one is uncomfortable or unfamiliar with. An inexperienced user should always start at very low dosages with the goal of working their way up in small increments as they feel comfortable doing so. This should be done by slightly increasing the dosage with each separate experience and never taking great leaps into the unknown.

Doing so allows people to get a feel for the substance that they are using in a controlled setting before they dive into deeper states. For pressed pills or tabs, one should buy from a reliable source with consistent product and ask questions concerning purity and how many milligrams of a drug is in the product.

This minimizes the risk of an accidental negative experience enormously; it is important to remember that everybody reacts differently to every substance depending on factors such as their own personal tolerance, neurophysiology, body weight, metabolism, and personal sensitivity. Another factor to consider is drug purity which differs between batches of product.

For information on the appropriate dosage for any substance, research should be done using a combination of PsychonautWiki, Erowid, Tripsit, Wikipedia and Google.

Allergy testing

Some people, especially those with health issues, have adverse reactions to drugs such as allergic reactions, uncomfortable physical or cognitive effects, or over-sensitivity.[1] The best way to prevent this is to perform an allergy test, which is simply dosing a minuscule amount of the drug (1/4 of a regular dose) and waiting several hours to a few days.

When performing an allergy test, one should note any dangerous side effects including rashes, hives, breathing discomfort, an uncomfortably fast heartbeat, or a burning sensation on one's skin.[1] Depending on the severity of symptoms, medical services may be needed.

Measuring dosages

There are various ways in which users measure their dosages. The most accurate and safe method to measure one's drugs is to use both a milligram scale and the volumetric liquid dosing method. This is a far safer route than "eyeballing" one's dosages by approximating the weight of what they are ingesting simply by looking at it and making a rough (but inaccurate) guess.

Eyeballing

Eyeballing is a highly inaccurate method of measuring substances which involves looking at a substance and making a rough guess of the weight. Since there is not much difference between 10mg and 30mg visually, it is highly discouraged.[2] There are numerous forms of eyeballing methods, including using micro scoops and the graph paper method.

  • Measuring scoops
  • Graph paper method - In this method, a known quantity of a substance is spread evenly onto a piece of graph paper and one's doses are based on how many graph paper squares are covered. This method is inaccurate simply because the volume of a measured weight of powder can vary significantly in its density, even with different batches of the same substance.[3] For example, two equal-sized piles of mescaline can have completely different densities and therefore different weights.

Users should not trust a vendor's word that their product weighs a certain amount as it is not unheard of for vendors to accidentally or intentionally give out the wrong amount of a product, resulting in overdoses for some users.[3]

It is especially dangerous to eyeball substances that have extremely low doses (under 10mg).

Milligram scales

The GEMINI-20 portable milligram scale shown above is a popular scale recommended by Tripsit. These can be purchased here.

When buying chemicals in powdered form, it is strongly recommended that one invest in a reliable and accurate digital milligram scale to ensure that they are ingesting a safe and recommended dosage.

To achieve the most accurate measurement, the scale should only be used on a completely flat surface away from vibrations, wind, and drafts. Low batteries can also affect the scale's accuracy, so one should occasionally replace them.[4]

There are a huge variety of different scales available online through various sites. To choose a quality scale, users should read the reviews before buying and come to their own personal decision. Users should ideally choose a scale that has a 0.001g readability. When using a scale that has 0.005 gram readability (5mg), the weight will be off by 5mg in either direction, meaning that if one measures 20mg of a substance, the results will be between 15-25mg.

For general purpose usage, the following products are recommended by TripSit:[5]

Please note that these milligram scales cannot accurately weigh out doses below 50mg and are highly inaccurate under 10-15mg. For potent drugs, please use volumetric liquid dosing.

Weighing technique

Most milligram scales are more accurate in higher ranges (5 - 15 grams) than the lower ranges. Therefore, it is better to weigh one's drug while the 10 gram weight is on the scale. The following steps outline the weighing method for the most accurate measurement:

  1. Place scale on completely flat surface away from wind and vibrations
  2. Calibrate scale
  3. Add 10 gram weight onto scale without tarring
  4. Add empty gel capsule and mark down weight without tarring
  5. Add the powder into the gel capsule
  6. Mark down weight of filled capsule
  7. Subtract the weight in step 4 from the final weight in step 6
  8. Use volumetric liquid dosing afterwards, especially for very potent drugs (under 10mg)

Volumetric liquid dosing

Main article: Volumetric liquid dosing

Volumetric liquid dosing should preferably be used for potent drugs because most standard milligram scales cannot accurately weigh out doses below 10-15mg.[6]

Volumetric liquid dosing is the process of dissolving a compound in a liquid to make it easier to measure. In the interest of harm reduction, it is essential to prepare certain compounds which are too potent to measure with traditional weighing scales within a liquid solution. Please see the above article for more information about this form of measurement.

Frequently insufflating (snorting) substances can damage one's mucous membranes, induce bleeding, damage the nostril's cartilage and lining, burn the throat, and cause other trauma to the nasal passage and sinus area.[7] To reduce damage, it is recommended to grind the substance completely before use, alternate nostrils, and to only insufflate infrequently.[8]

Sublingual

Sublingual administration refers to the absorption under the tongue which can result in a faster absorption than oral use.[9] Caustic substances such as quetiapine or phenibut should not be used sublingually because they can burn the inside of one's mouth if left in one spot for too long.

Smoked

Intravenous (IV)

Intramuscular (IM)
