Alcohol is absorbed into the bloodstream primarily through the walls of the stomach and small intestine. Once in the bloodstream, it is carried to various organs in the body, including the brain, where it exerts its effects.
When cocaine is snorted or inhaled, it is absorbed through the nasal tissues into the bloodstream. If it is injected, it goes directly into the bloodstream. Once in the bloodstream, cocaine travels to the brain where it exerts its effects. It is then metabolized by the liver and eventually excreted from the body in urine.
Alcohol enters the bloodstream through absorption in the stomach and small intestine. It is then carried through the bloodstream to the brain and other organs, where it can have various effects on the body.
A few minutes
Alcohol can reach the brain within minutes after being ingested, as it is absorbed directly into the bloodstream through the lining of the stomach and small intestine. The effects of alcohol on the brain can be felt quickly, though the full impact can vary based on factors like the amount consumed and an individual's tolerance.
When alcohol and barbiturates are ingested, they are absorbed from the GI tract and transported first to the liver before circulating to the rest of the body. In the liver, these substances are metabolized before being distributed through the bloodstream to the brain and other organs. This process can affect central nervous system function and lead to intoxication or sedation.
No. Your body doesn't realise it is being poisoned and take steps to remove it (i.e. by throwing it up) until a large amount of alcohol has already been absorbed into the bloodstream and transported to the brain.

Nicotine enters your bloodstream when you inhale smoke from a cigarette or other tobacco product. The nicotine is absorbed through the lungs and quickly enters the bloodstream, reaching the brain within seconds.
No, sniffing alcohol cannot get you drunk. Alcohol must be ingested to enter the bloodstream and affect the brain to cause intoxication. Sniffing alcohol can be dangerous and harmful to your health.
Through absorption by your stomach and small intestine.
From the first sip, alcohol is absorbed into the bloodstream and reaches the brain which deteriorates further the more you drink. Cognitive abilities that are acquired later in life, such as conduct and behaviour, are the first to go. Early on you will experience mild euphoria and loss of inhibition, as alcohol impairs regions of the brain controlling behaviour and emotion. Most vulnerable are the brain cells associated with memory, attention, sleep and coordination.
