Drug Addictions

Marijuana Addiction:
Heavy or daily use of marijuana affects the parts of the brain that control memory, attention and learning and can make it more difficult to learn and perform tasks that call for more than one or two steps.

• Smoking marijuana causes some changes in the brain that are like those caused by cocaine, heroin and alcohol. Scientists are still learning about the many ways that marijuana can affect the brain.

• One joint can deliver four times as much cancer-causing tar as one tobacco cigarette.
The marijuana that teens use today has more than twice the concentration of THC, the chemical that affects the brain, than the marijuana of 20 years ago.
Young people who use marijuana weekly have double the risk of depression later in life, and teens who smoke marijuana weekly are three times more likely than non-users to have suicidal thoughts. Marijuana use in some teens has been linked to increased risk for schizophrenia in later years.

Cocaine Abuse Symptoms, Signs and Addiction Treatment


Cocaine usually tops the list when it comes to common illicit drugs. It is a powerful stimulant that is frequently abused and is highly addictive. Users typically snort the drug in powder form, but it can also be turned into a liquid and injected or into a rock and smoked. Cocaine users typically experience a sense of euphoria immediately after taking the drug. This blissful feeling is what makes users want to take the drug again and again, which leads to abuse and addiction.
Cocaine is not physically addictive, meaning there are no physical withdrawal symptoms when you stop taking it, as is the case with many other illicit drugs. This is one of the most misleading cocaine abuse facts, because many people think this means they can’t become addicted to it. A study by the Substance Abuse and Health Service Administration (SAMHSA) reports that up to half of drug-related visits to emergency rooms in the United States are related to cocaine abuse. Even casual use can lead to a cocaine problem, but help is available.
What Adverse Effects Does Cocaine Have on Health?
Abusing cocaine has a variety of adverse effects on the body. For example, cocaine constricts blood vessels, dilates pupils, and increases body temperature, heart rate, and blood pressure. It can also cause headaches and gastrointestinal complications such as abdominal pain and nausea. Because cocaine tends to decrease appetite, chronic users can become malnourished as well.

Different methods of taking cocaine can produce different adverse effects. Regular intranasal use (snorting) of cocaine, for example, can lead to loss of the sense of smell; nosebleeds; problems with swallowing; hoarseness; and a chronically runny nose. Ingesting cocaine can cause severe bowel gangrene as a result of reduced blood flow. Injecting cocaine can bring about severe allergic reactions and increased risk for contracting HIV and other blood-borne diseases. Binge-patterned cocaine use may lead to irritability, restlessness, and anxiety. Cocaine abusers can also experience severe paranoia—a temporary state of full-blown paranoid psychosis—in which they lose touch with reality and experience auditory hallucinations.

Regardless of the route or frequency of use, cocaine abusers can experience acute cardiovascular or cerebrovascular emergencies, such as a heart attack or stroke, which may cause sudden death. Cocaine-related deaths are often a result of cardiac arrest or seizure followed by respiratory arrest

What Is Narcotic Abuse?

One of the most frequent reasons people go to the doctor is for pain relief. There are a number of different drugs that can ease pain. 
Opioids -- also called opiates or narcotics -- are pain relievers made from opium, which comes from the poppy plant. Morphine and codeine are the two natural products of opium. Synthetic modifications or imitations of morphine produce the other opioids:
  • Heroin (street drug
  • Dilaudid (hydromorphone)
  • Percocet, Percodan, OxyContin (oxycodone)
  • Vicodin, Lorcet, Lortab (hydrocodone)
  • Demerol (pethidine)
  • Methadone
  • Duragesic (fentanyl)
When people use narcotics only to control pain, they are unlikely to become addicted to the drugs. However, opioids provide an intoxicating high when injected or taken orally in high doses. Opioids are also powerful anxiety relievers. For these reasons, narcotic abuse is one of the most common forms of drug abuse in the U.S.

  • Euphoria (feeling high)

Regardless of the method of abuse, heroin addiction often occurs as a result of frequent use.
