Psychedelic Research Chemicals or RC Chems are new synthetic substances which are structurally similar to the original drug, while being functional analogs. Data on their effects limited due as they’re fairly new and do not have a lot of human consumption history.

Psychedelics are substances (natural or laboratory made) which cause profound changes in a one’s perceptions of reality. While under the influence of hallucinogens, users might hallcuniate visually and auditorily.

Disclaimer: Psychedelic drugs offer some of the most powerful and intense psychological experiences. Additionally these substances are illegal in many places. We understand that even though these substances are illegal, their use occurs frequently. We do not condone breaking of the law. By providing accurate information about these substances, we encourage the user to make responsible decisions and practice harm reduction.

Ethylcathinone is a synthetic stimulant. It is similar to ecstasy in the sense that it provides euphoria, feelings of empathy and openness, and a desire to talk with others. It also carries over to some of the negative effects of ecstasy, such as insomnia, tightened jaw muscles, and grinding of the teeth.


It is structurally related to cathinone and methcathinone (MCAT), which broadly shares the effects profile of amphetamine or methylphenidate. Of the substituted cathinones, ETH-CAT reportedly produces the most moderate and residually long-lasting stimulation, with subtle effects that persist well after the initial rush. It has been described as having a more functional than recreational character due to the limited euphoria it produces for a stimulant, although its short active duration can promote compulsive redosing.

Very little data exists about the pharmacological properties, metabolism, and toxicity of ETH-CAT, and it has little history of human usage. It is primarily distributed as a research chemical on the online grey market. In 2008 it was identified as an ingredient in both quasi-legal “party pills”.

It has also been reported as having been sold as “ecstasy” along with another substituted cathinone, mephedrone. It is highly advised to use harm reduction practices if using this substance.


Substituted cathinones are all derivatives of cathinone, a stimulant substance which is structurally and functionally related to amphetamine and the principal active psychoactive component present in the khat plant (Catha edulis).

The cathinone molecule is comprised of a phenethylamine core featuring a phenyl ring bound to an amino (NH2) group at the end of an ethyl side-chain that contains ketone group in the beta position. In distinction to its N-methylated lower homolog, methcathinone (M-CAT), ETH-CAT possesses an additional ethyl substitution at Rα.

ETH-CAT can be thought of as the cathinone analog of ethylamphetamine given it has the same general formula, differing only by the addition of a single double-bonded oxygen (i.e.

the ketone group).

Dose Chart


Duration Chart

Onset15-60 minutes
Duration2-5 hours
After-effects2-3 hours



  1. Mushrooms
    • Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences
  2. LSD
    • Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences
  3. DMT
    • Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences
  4. Mescaline
    • The focus and anxiety caused by stimulants is magnified by psychedelics and results in an increased risk of thought loops
  5. 2C-x
    • The anxiogenic and focusing effects of stimulants increase the chance of unpleasant thought loops. The combination is generally uneccessary because of the stimulating effects of psychedelics. Combination of the stimulating effects may be uncomfortable.
  6. Cannabis
    • Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences
  7. Ketamine
    • No unexpected interactions, though likely to increase blood pressure but not an issue with sensible doses. Moving around on high doses of this combination may be ill advised due to risk of physical injury.
  8. MXE
    • Risk of tachycardia, hypertension, and manic states
  9. Cocaine
    • This combination of stimulants will increase strain on the heart. It is not generally worth it as cocaine has a mild blocking effect on dopamine releasers like amphetamine
  10. Caffeine
    • This combination of stimulants is not generally necessary and may increase strain on the heart, as well as potentially causing anxiety and greater physical discomfort.
  11. Alcohol
    • Drinking on stimulants is risky because the sedative effects of the alcohol are reduced, and these are what the body uses to gauge drunkenness. This typically leads to excessive drinking with greatly reduced inhibitions, high risk of liver damage and increased dehydration. They will also allow you to drink past a point where you might normally pass out, increasing the risk. If you do decide to do this then you should set a limit of how much you will drink each hour and stick to it, bearing in mind that you will feel the alcohol and the stimulant less. Extended release formulations may severely impede sleep, further worsening the hangover.
  12. GHB/GBL
    • Stimulants increase respiration rate allowing a higher dose of sedatives. If the stimulant wears off first then the opiate may overcome the patient and cause respiratory arrest.
  13. Opioids
    • Stimulants increase respiration rate allowing a higher dose of opiates. If the stimulant wears off first then the opiate may overcome the patient and cause respiratory arrest.


  1. DOx
    • The combined stimulating effects of the two can lead to an uncomfortable body-load, while the focusing effects of amphetamine can easily lead to thought loops. Coming down from amphetamines while the DOx is still active can be quite anxiogenic.
  2. NBOMes
    • Amphetamines and NBOMes both provide considerable stimulation. When combined they can result in tachycardia, hypertension, vasoconstriction and in extreme cases heart failure. The anxiogenic and focusing effects of stimulants are also not good in combination with psychedelics as they can lead to unpleasant thought loops. NBOMes are known to cause seizures and stimulants can increase this risk.
  3. 2C-T-x
    • Stimulants increase anxiety levels and the risk of thought loops which can lead to negative experiences. In extreme cases, they can result in severe vasoconstriction, tachycardia, hypertension, and in extreme cases heart failure.
  4. 5-MeO-xxT
    • The anxiogenic and focusing effects of stimulants increase the chance of unpleasant thought loops. The combination is generally unnecessary because of the stimulating effects of psychedelics.
  5. DXM
    • Both substances raise heart rate, in extreme cases, panic attacks caused by these drugs have led to more serious heart issues.
  6. PCP
    • This combination can easily lead to hypermanic states

Low Synergy

  1. Benzodiazepines
    • Both can dull each other's effects, so if one wears off before the other it's possible to overdose due to the lack of counteraction

No Synergy

  1. SSRIs

High Synergy

  1. N2O
  2. MDMA
    • Amphetamines increase the neurotoxic effects of MDMA

Legal Status

ETH-CAT is currently a grey area compound within many parts of the world. People may still be charged for its possession under certain circumstances such as under analogue laws and with intent to sell or consume.

  • Brazil: On September 7, 2018, all cathinone analogues are controlled substances considered illegal to possess, use and distribute. This was made possible due to a blanket ban law appended to Portaria SVS/MS nº 344.
  • China: As of October 2015 Ethylcathinone is a controlled substance in China.
  • Denmark: Ethcathinone, along with mephedrone and flephedrone, was banned in Denmark on December 18, 2008.
  • Germany: Ethylcathinone is controlled under Anlage II BtMG (Narcotics Act, Schedule II) as of July 26, 2012. It is illegal to manufacture, possess, import, export, buy, sell, procure or dispense it without a license.
  • United Kingdom: Ethylcathinone is a Class B drug in the United Kingdom as a result of the cathinone catch-all clause.
  • United States: Ethylcathinone may be considered to be an analogue of amphetamine under the Federal Analogue Act.The Federal Analogue Act, 21 U.S.C. § 813, is a section of the United States Controlled Substances Act, allowing any chemical "substantially similar" to an illegal drug (in Schedule I or II) to be treated as if it were also in Schedule I or II, but only if it is intended for human consumption.
