Heroin is a highly addictive drug causing a lot of addicts and problems in the US and Europe. Currently about 600.000 people are undergoing treatment for heroin addiction in the US. With heroin abuse, tolerance develops and the abuser have to use more every time to achieve the same intensity or effect. The short term effects from heroin abuse appear short time after you take the dose and disappear after a few hours. The users report of some kind of rush of well-being together with a warm flushing of the skin, dry mouth and heavy extremities. Following the users go "on the nod", an alternately wakeful and drowsy state. Mental functioning becomes cloudy and weak due to the depression of the central nervous system. The long term effects from heroin are collapsed veins, infection of the heart lining and valves, abscesses, cellulitis and liver damage. Various types of pneumonia and respiration may also result. Street heroin may also have additives that may clog the blood vessels that leads to the lungs, liver, kidneys or brain, which can cause infection or even death. Heroin abuse is also associated with overdoses, spontaneous abortions, and infectious diseases such as HIV and AIDS. Just a few hours after the last injection (snort or smoke), addicts will start crave for more, feel restless, get muscle and bone pain, insomnia, diarrhea, throwing up, cold swapes with goose bumps ("cold turkey"), kicking movements and other symptoms. Major withdrawal symptoms peak 48- 72 hours after the last dose and last for about one week. Heroin withdrawal is considered much less dangerous than alcohol or barbiturate withdrawal. SPEEDAll forms are extremely dangerous and involves long-lasting debilitates. Speed is an addictive stimulant drug that strongly activates certain systems in the brain and effects the central nervous system stronger than any other drug. When speed is swallowed or snorted it produces euphoria. It's a high, but not a rush. When injected or smoked, the user experiences a rush which is described as extremely pleasurable that lasts a few minutes. Abusers may be addicted quickly with more frequent use and larger doses. Over time, speed appears to cause reduced levels of dopamine, which stimulates brain cells, enhance mood and body movement, which can result in symptoms like those of Parkinson's disease, a severe movement disorder. Research has also shown that nerve endings are cut back while re-growth are limited. The central nervous system actions that result from taking even small amounts of speed include increased wakefulness, increased physical activity and respiration, decreased appetite, hyperthermia, and euphoria. Other effects include irritability, insomnia, confusion, tremors, convulsions, anxiety, paranoia, and aggressiveness. Hyperthermia and convulsions can result in death. Speed causes increased heart rate and blood pressure and can cause irreversible damage to blood vessels in the brain, producing strokes. Other effects of speed include respiratory problems, irregular heartbeat, and extreme anorexia. Its use can result in cardiovascular collapse and death. ! speed IS BAD!
