Categorisations

Low Risk & Synergy - These drugs work together to cause an effect greater than the sum of its parts, and they aren't likely to cause an adverse or undesirable reaction when used carefully. Additional research should always be done before combining drugs.

Low Risk & No Synergy - Effects are just additive. The combination is unlikely to cause any adverse or undesirable reaction beyond those that might ordinarily be expected from these drugs.

Caution - These combinations are not usually physically harmful, but may produce undesirable effects, such as physical discomfort or overstimulation. Extreme use may cause physical health issues. Synergistic effects may be unpredictable. Care should be taken when choosing to use this combination.

Unsafe - There is considerable risk of physical harm when taking these combinations, they should be avoided where possible.

Dangerous - These combinations are considered extremely harmful and should always be avoided. Reactions to these drugs taken in combination are highly unpredictable and have a potential to cause death.

Status: Caution

Note: Coadministration of monoamine oxidase inhibitors (MAOIs) with certain opioids has been associated with rare reports of severe and fatal adverse reactions. There appear to be two types of interaction, an excitatory and a depressive one. Symptoms of the excitatory reaction may include agitation, headache, diaphoresis, hyperpyrexia, flushing, shivering, myoclonus, rigidity, tremor, diarrhea, hypertension, tachycardia, seizures, and coma. Death has occurred in some cases.

ssris & opioids

Status: Low Risk & No Synergy

Note: There have been very infrequent reports of a risk of serotoninA monoamine neurotransmitter, biochemically derived from tryptophan, that is primarily found in the gastrointestinal (GI) tract, platelets, and central nervous system (CNS) of humans and animals. It is a well-known contributor to feelings of well-being. syndrome with this combination, though this should not be a practical concern.

Status: Dangerous

Note: Central nervous system- and/or respiratory-depressant effects may be additively or synergistically present. Vomit aspiration a risk when passed out, lay down in recovery position if ingested.

The DOx class as psychedelic stimulants have the potential to mask the effects of DXM and could lead to redosing to an unsafe level. DXM can also potentiate DOx resulting in an unpleasantly intense experience.

DOx & Nitrous

DOx & Amphetamines

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.

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.

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 A neurotransmitter associated with movement, attention, learning, and the brain’s pleasure and reward system. releasers like amphetamine.

Amphetamines & 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.

Amphetamines & 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.

Amphetamines & 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.

Amphetamines & Opioids

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 he alcohol less. Cocaine is potentiated somewhat by alcohol by reduction of cocaine breakdown which results in increased risk to the heart.

Cocaine & 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. Likewise the G can wear off and leave a dangerous concentration of cocaine behind.

Cocaine & 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.

Even in very low doses this combination rapidly leads to memory loss, severe ataxia Loss of motor coordination and unconsciousness. There is a high risk of vomit aspiration while unconscious.

Alcohol & Opioids

Both substances potentiate the ataxia Loss of motor coordination and sedation caused by the other and can lead to unexpected loss of consciousness at high doses. Place affected patients in the recovery position to prevent vomit aspiration from excess. Memory blackouts are likely.

Alcohol & Tramadol

Heavy CNS Central Nervous System depressants, risk of seizures. Both substances potentiate the ataxia Loss of motor coordination and sedation caused by the other and can lead to unexpected loss of consciousness at high doses. Place affected patients in the recovery position to prevent vomit aspiration from excess. Memory blackouts are likely.

Alcohol & Benzodiazepines

Ethanol ingestion may potentiate the CNS Central Nervous System effects of many benzodiazepines. The two substances potentiate each other strongly and unpredictably, very rapidly leading to unconsciousness. While unconscious, vomit aspiration is a risk if not placed in the recovery position. Blacking out and memory loss is almost certain.

Alcohol & MAOIs

The chemical tyramine in alcoholic beverages can have dangerous reactions with MAOIs, causing an increase in blood pressure.

B inhibitors should enhance the effects, no interaction with MAO Monoamine Oxidase, an enzyme that catalyses the metabolism of many drugs (e.g., DMT, dopamine and serotonin). A.

GHB\GBL & SSRIs

Opioids & Tramadol

Concomitant use of tramadol increases the seizure risk in patients taking other opioids. These agents are often individually epileptogenic and may have additive effects on seizure threshold during coadministration. Central nervous system- and/or respiratory-depressant effects may be additively or synergistically present.

Opioids & Benzodiazepines

Central nervous system and/or respiratory-depressant effects may be additively or synergistically present. The two substances potentiate each other strongly and unpredictably, very rapidly leading to unconsciousness. While unconscious, vomit aspiration is a risk if not placed in the recovery position Blackouts/memory loss likely.

Opioids & MAOIs

Coadministration of monoamine oxidase inhibitors (MAOIs) with certain opioids has been associated with rare reports of severe and fatal adverse reactions. There appear to be two types of interaction, an excitatory and a depressive one. Symptoms of the excitatory reaction may include agitation, headache, diaphoresis, hyperpyrexia, flushing, shivering, myoclonus, rigidity, tremor, diarrhea, hypertension, tachycardia, seizures, and coma. Death has occurred in some cases.
