One of the most detrimental long-term effects of heroin is heroin addiction itself. Addiction is a chronic problem, characterized by compulsive drug seeking and use, and by neurochemical and molecular changes in the brain. Heroin also produces profound degrees of tolerance and physical dependence, which are also powerful motivating factors for compulsive use and abuse. See similar questions...

Soon after injection (or inhalation), heroin crosses the blood-brain barrier. In the brain, heroin is converted to morphine and binds rapidly to opioid receptors. Abusers typically report feeling a surge of pleasurable sensation, a "rush." The intensity of the rush is a function of how much drug is taken and how rapidly the drug enters the brain and binds to the natural opioid receptors. Heroin is particularly addictive because it enters the brain so rapidly. See similar questions...

The wavelength used by the Virulite device is very close to that of the Nd:YAG laser which has been used by doctors all over the world for several decades. The Virulite Cold Sore Machine radiates divergent light which is inherently 'eye-safe' and uses powers 1/10'000 less than medical lasers already in use. It has been documented in medical papers that Nd:YAG laser surgery to a pregnant woman's cervix (neck of the womb) is a safe procedure if clinically indicated. See similar questions...

Heroin addiction like all opiate addictions occurs when heroin is administered over a sustained period of time. The onset of heroin addiction can be both rapid and severe, dependent on the amount used and frequency in a designated period of time. Heroin addicts will "crave" more of the drug and experience withdrawal symptoms if they do not get their regular "fix" or dose. Not all of the mechanisms by which heroin and other opiates affect the brain are known. See similar questions...

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. See similar questions...

Methamphetamine, like cocaine, is a "psychostimulant" that increases the amount of at least three important brain chemicals called neurotransmitters: dopamine, serotonin and norepinephrine. As a result, methamphetamine can elevate your mood, induce euphoria, increase alertness, reduce fatigue, increase energy, decrease appetite, increase movement and speech, and provide a sense of increased personal power and prowess.

Medical consequences of chronic heroin abuse include scarred and/or collapsed veins, bacterial infections of the blood vessels and heart valves, abscesses (boils) and other soft-tissue infections, and liver or kidney disease. Lung complications (including various types of pneumonia and tuberculosis) may result from the poor health condition of the abuser as well as from heroin's depressing effects on respiration. See similar questions...

Methamphetamine causes increased heart rate and can cause irreversible damage to blood vessels in the brain. Over time, methamphetamine reduces levels of dopamine (which stimulates brain cells) resulting in symptoms like those found in diseases that reflect a severe movement disorder. Other effects of methamphetamine include respiratory problems, extreme anorexia, pounding blood pressure, sleep interference, mood swings, unpredictability, and tremors. (http://www.theantidrug.

In considering the long-term effects of TBI on the individual, it is most important to emphasize that there is no "typical" person with TBI. People who have experienced a TBI vary on many dimensions: 1) severity of initial injury; 2) rate and completeness of physiological healing; 3) types of functions affected; 4) meaning of dysfunction in the individual's life, in the context of his/her roles, values, and goals; 5) resources available to aid recovery of function; and so forth.
