[[File:TripSit's Dangerous combination chart.png|400px|thumb|right|A useful chart from [https://tripsit.me/ TripSit.me] which can be used to identify dangerous drug combinations quickly and easily.]]

Although many substances are safe on their own, they can become dangerous and even life-threatening when combined with other substances. Certain combinations may be safe in low doses of each but still increase the potential risk of death. [https://www.google.com/ Independent research] should always be done to ensure that a combination of two or more substances is safe before consumption.

Substance related deaths most commonly occur when combining [[depressants]]. Depressants affect the parts of the nervous system responsible for breathing, and an overdose or combination of these substances can result in fatal levels of [[respiratory depression]]. Death may also occur when a victim falls into deep enough unconsciousness to aspirate on their own vomit. Lying in the [[recovery position]] can prevent one from suffocating on their own vomit.

*'''[[Depressants]]''' (''[[1,4-Butanediol]], [[2-methyl-2-butanol]], [[alcohol]], [[barbiturates]], [[GHB]]/[[GBL]], [[methaqualone]], [[opioids]]'') - This combination can result in dangerous or even fatal levels of [[respiratory depression]]. These substances potentiate the [[muscle relaxation]], [[sedation]] and [[amnesia]] caused by one another and can lead to unexpected loss of consciousness at high doses. There is also an increased risk of vomiting during unconsciousness and death from the resulting suffocation. If [[nausea]] or vomiting occurs, users should attempt to fall asleep in the [[recovery position]] or have a friend move them into it.

It is important to note that this interaction does NOT follow linear pharmacokinetics i.e. the depressant effects from the interaction are multiplicative instead of additive.{{citation needed}}

*'''[[Dissociatives]]''' - This combination can result in an increased risk of vomiting during unconsciousness and death from the resulting suffocation. If [[nausea]] or vomiting occurs, users should attempt to fall asleep in the [[recovery position]] or have a friend move them into it.

*'''[[Stimulants]]''' - It is dangerous to combine benzodiazepines with [[stimulant]]s due to the risk of excessive intoxication. Stimulants decrease the [[sedation|sedative]] effect of benzodiazepines, which is the main factor most people consider when determining their level of intoxication. Once the stimulant wears off, the effects of benzodiazepines will be significantly increased, leading to intensified [[disinhibition]] as well as [[benzodiazepine#Subjective effects|other effects]]. If combined, one should strictly limit themselves to only dosing a certain amount of benzodiazepines per hour. This combination can also potentially result in severe dehydration if hydration is not monitored.

Stimulants decrease the [[sedation|sedative]] effect of alcohol, which is the main factor most people consider when determining their level of intoxication. Alcohol also appears to have addictive effects on stimulants compared to taking either of them alone. For instance a study found that concentration d-[[methylphenidate]] concentration in the brain are increased by up to 30% when mixed with alcohol. Another study had also found that when there is concurrent administration of [[methamphetamine]] (30 mg intravenously) and [[ethanol]] (1 gm/kg orally over 30 minutes) increased heart rate by 24 beats/minute compared to methamphetamine alone. Once the stimulant wears off, the effects of alcohol will be significantly increased, leading to intensified [[disinhibition]] as well as [[Alcohol#Subjective effects|other effects]].

*[[MAOI|'''~~MAOIs''']]~~ - This combination can result in dangerous reactions through the way in which tyramine, a chemical commonly found in alcoholic beverages, causes [[increased blood pressure]].

===[[Psychedelics]]===

'''NOTE:''' Because of the relatively high unpredictability of psychedelics, it is usually advised (especially if the person has little or no experience) to avoid mixing them with any other substance, even if the mix is considered physically safe. Even a substance like [[Alcohol]], which tends to dull the psychedelic effects, could trigger a state of confusion which might cause the person to have a negative experience.

*'''[[Cannabis]]''' - This combination is very unpredictable. Some people like and advise to smoke during a trip to make the experience more relaxing, but in many cases it seems to potentiate the psychedelic effect and/or make the experience more intricate and confusing. This is usually not physically dangerous, but might cause a [[Bad trip]] by making the experience too overwhelming and disorienting.

*'''[[Stimulants]]''' - This combination tends to increase anxiety, thus increasing the possibility of having a negative experience. If the psychedelic substance used is already stimulating on its own (for example a [[Phenethylamine]]) a mix like this could cause an increase in heart rate and/or other unpleasant physical and psychological symptoms.
