Both substances cause ataxia and bring a very high risk of vomiting and unconsciousness. If the user falls unconscious while under the influence there is a severe risk of vomit aspiration if they are not placed in the recovery position.

There is a high risk of memory loss, vomiting and severe ataxia from this combination.

Both substances potentiate the ataxia 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. Additionally CNS depression can lead to difficulty breathing. Avoid on anything higher than 1st plateau.

Details of this combination are not well understood but PCP generally interacts in an unpredictable manner.

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 less. Cocaine is potentiated somewhat by alcohol because of the formation of cocaethylene.

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

Both substances potentiate the ataxia 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

Heavy CNS depressants, risk of seizures. Both substances potentiate the ataxia 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.

Ethanol ingestion may potentiate the CNS 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.

Tyramine found in many alcoholic beverages can have dangerous reactions with MAOIs, causing an increase in blood pressure.

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.

Both MDMA and alcohol cause dehydration. Approach this combination with caution, moderation and sufficient hydration. More than a small amount of alcohol will dull the euphoria of MDMA

Alcohol may potentiate some of the pharmacologic effects of CNS-active agents. Use in combination may result in additive central nervous system depression and/or impairment of judgment, thinking, and psychomotor skills.
