"Cocaine's effects appear almost immediately after a single dose, and disappear within a few minutes or hours. Taken in small amounts (up to 100 mg), cocaine usually makes the user feel euphoric, energetic, talkative, and mentally alert, especially to the sensations of sight, sound, and touch. It can also temporarily decrease the need for food and sleep.
Some users find that the drug helps them to perform simple physical and intellectual tasks more quickly, while others can experience the opposite effect. The duration of cocaine's immediate euphoric effects depends upon the route of administration.
The faster the absorption, the more intense the high. Also, the faster the absorption, the shorter the duration of action. The high from snorting is relatively slow in onset, and may last 15 to 30 minutes, while that from smoking may last 5 to 10 minutes.
The short-term physiological effects of cocaine include constricted blood vessels; dilated pupils; and increased temperature, heart rate, and blood pressure. Large amounts (several hundred milligrams or more) intensify the user's high, but may also lead to bizarre, erratic, and violent behavior.
These users may experience tremors, vertigo, muscle twitches, paranoia, or, with repeated doses, a toxic reaction closely resembling amphetamine poisoning. Some users of cocaine report feelings of restlessness, irritability, and anxiety.
In rare instances, sudden death can occur on the first use of cocaine or unexpectedly thereafter. Cocaine-related deaths are often a result of cardiac arrest or seizures followed by respiratory arrest."

1. effects on the body (the brain)
How cocaine affects the brain
Cocaine causes interesting effects in the brain. Scientists have long studied the effects of cocaine use on the brain, mainly to discover the secret of why it is so addictive, as well as why it is so hard to stop abusing cocaine once started.
Deep in the brain, there are centers that provide feelings of euphoria and pleasure. These are known as reward centers. An event that is "rewarding" is accompanied by the release of a chemical known as dopamine. Dopamine allows feelings of pleasure and euphoria. Normally, the dopamine is released into small gaps between neurons in the brain. It binds with proteins in the gaps and sends the appropriate signals to the brain. The dopamine eventually leaves the gap.
With cocaine substance abuse, this process is disrupted. Cocaine actually blocks the dopamine from leaving the gaps between the brain's neurons, and this leads to a buildup of dopamine; the brain then remains stimulated.
However, this alteration of how the brain works comes with a price. The body develops a tolerance - becoming used to - the level of pleasure felt with the initial use of cocaine. More and more cocaine is required to get the same effect. Additionally, the brain retains a memory of the euphoria, and can trigger intense cravings that can lead to relapse.
2. effects on the mind:
covered also in #1
3. effects on behavior:
Cocaine is an addictive stimulant that causes a user to lose interest in life activities, such as school, work, sports, and family. Users can begin to experience paranoia and anxiety.1 While users are high, they feel a sense of euphoria and strength; however they become depressed after about 20 minutes.
* Also causes irritability and restlessness.
* High doses may result in psychosis, hallucinations, and aggressiveness.
* A user may become very tired and sleep for long periods of time once the high has worn off.
