Explanation of these drug types.
Stimulants: drugs which elevate mood, increase wakefulness and give an increased sense on mental and physical energy.e.g caffeine. Opiates: It is often called narcotic analgesics because they are strong painkillers and because they produce a feeling of euphoria and sleepiness. Hallucinogens: Hallucinogens are among the oldest known drugs that have been used for their ability to alter human perception and mood.
Most drugs of abuse can be placed in the above categories although some marijuana, cannabis, nicotine and solvents must be considered separately as they do not fit into the above categories.
As marijuana enters the brain, it causes the user to feel euphoric—or high—by acting on the brain's reward system, which is made up of regions that govern the response to pleasurable things like sex and chocolate, as well as to most drugs of abuse. Marijuana activates the reward system in the same way that nearly all drugs of abuse do: by stimulating brain cells to release the chemical dopamine. Along with euphoria, relaxation is another frequently reported effect in human studies. Other effects, which vary dramatically among different users, include heightened sensory perception (e.g., brighter colors), laughter, altered perception of time, and increased appetite. After a while, the euphoria wears -off and the user may feel sleepy or depressed. Occasionally, marijuana use may produce anxiety, fear, distrust, or panic. Marijuana users who have taken large doses of the drug may experience an acute psychosis, which includes hallucinations, delusions, and a loss of the sense of personal identity. Short-term psychotic reactions to high concentrations of marijuana are distinct from longer-lasting, schizophrenia-like disorders that have been associated with the use of cannabis in vulnerable individuals
Ecstasy has a rep for being a party drug. But side effects like tremors, teeth clenching and nausea, not to mention anxiety, depression and possible brain damage, will suck all the life out of any party, fast. What is it?
Ecstasy's medical name is MDMA (methylenedioxy-methamphetamine). It is a synthetic, mind-altering drug that acts both as a stimulant and a hallucinogenic. Research shows that many Ecstasy tablets contain a number of other drugs that can be dangerous when combined, including methamphetamine, ketamine, cocaine, DXM and the diet drug ephedrine. The Risks
Shortly after taking Ecstasy, you may feel confusion, depression and severe anxiety—but these effects can also show up days or weeks after taking the drug. Like any other stimulant, it will increase your heart rate and blood pressure. Physical effects of Ecstasy include tremors, teeth clenching, muscle cramps, nausea, faintness, chills, sweating and blurred vision. LONG-TERM EFFECTS
Ecstasy directly affects the brain chemical serotonin, and how your brain cells communicate with each other. Clinical studies show that Ecstasy can be harmful to your brain and can increase the risk of permanent problems with memory and learning. Also, taking too much Ecstasy can interfere with the body's ability to regulate its temperature. This can cause hyperthermia and can lead to liver, kidney and cardiovascular failure. THE BOTTOM LINE
The word is that Ecstasy lets you get in touch with all your senses. But what you might really "get in touch with" is the sensation of shaking, cramps, nausea, sweating and blurred vision-now, that doesn't really sound like fun. Also not fun, is the life-long damage Ecstasy can do to your brain.
