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.

This is an Experimental Substance with little data. This is most likely because the substance is is not very old. Information is limite and incomplete.

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.

Interactions

Caution

  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.

Dangerous

  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
