Physically, the effects of amphetamine abuse include chest pain, heart failure and convulsions. A person using the drug may be unaware of these effects and will find out of what’s happening only in case if he or she stops taking them.

Methamphetamine

Methamphetamine, or meth, crystal, chalk and ice, is a very addictive  stimulant of central nervous system having high potential for abuse. Taking small doses of methamphetamine result similar effects to such stimulants as cocaine or amphetamine.

Meth users feel more energetic, may not sleep for a long time. Depending on administration method a fast rush of euphoria is followed by quite long period of less intensive euphoria. When the drug was swallowed the high may last for about ten hours.

Opiates are a group of drugs, natural, synthetic or partially synthetic, used medically for treating pain. There are a great variety of opiates from legal fentanyl, codeine and morphine to illegal opium and heroin. If used as prescribed legal opiate are extremely effective remedies for pain relief. But even taken as prescribed the opioids have a high potential for abuse.

Marijuana is probably the most commonly used drug on the planet. People usually smoke marijuana in cigarettes, pipes or water pipes. Other methods are to mix it in food or smoke or eat different forms of THC-rich resins.

Benzodiazepines

Benzodiazepines, also called “benzos”, are a family of minor tranquilizers acting against anxiety and convulsions, and producing muscle relaxation and sedation. These drug abuse have a very high potential for abuse and addiction.

People usually start abusing benzodiazepines in one of two possible ways: they start taking the drug as prescribed and then progress to taking more than they need to, or they start taking them illicitly and become addicts.

PCP is illegally marketed under numerous street names such as angel dust, hog, rocket fluid etc. These names reflect bizarre and volatile effects of the drug using.

A moderate dose of PCP make users feel detached and estranged from their surroundings.

Methadone

Methadone is a synthetic narcotic drug, less addictive than heroine or morphine and used as a substitute for these drugs in treatment courses.

Methadone is a very long-lasting medication and that is why it is used for the relief of severe pain. Taking doses very often it is easy to overdose. Thousands of people die because of this every year.

Signs and symptoms:

  • slowed or troubled respiration;
  • dry mouth;
  • drowsiness;
  • impaired concentration;
  • irregular heart-beat;
  • facial flushing;
  • urinary retention;
  • unstable gait;

The opiate users often experience drowsiness, weakness, nausea, vomiting and constipation. He or she may also have dry mouth, headache, itchiness or loss of appetite.

Tricyclic Antidepressants

Tricyclic antidepressants were the earliest antidepressants developed in 1950s. They affect brain to ease symptoms of depression. Tricyclic antidepressants are amitriptyline, amoxapine, desipramine, doxepin, imipramine, nortriptyline, protriptyline, trimipramine. Tricyclic antidepressants may be recommended for the treatment if obsessive-compulsive disorder and enuresis. They are also used to treat anxiety disorders (panic disorder and chronic pain).

TCAs are not characterized by addictive potential of other psychoactive drugs, such as benzodiazepines or barbiturates. Most people can stop taking them without any problem. But the risk of fatal overdose abusing these antidepressants is very high. People taking tricyclic antidepressants must be monitored carefully by therapists.

Withdrawal symptoms include:

  • drowsiness;
  • blurred vision;
  • dry mouth;
  • constipation;
  • dizziness.

These symptoms are unlikely to occur if the dose is reduced gradually. In case if such symptoms occurred, they would last less than two weeks.

Treatment

Drug abuse is serious but still treatable medical problem. Proper treatment reduces the effect of drugs onto the brain and body and help people improve their functioning and physical health.

Nowadays many ways to treat substance abuse exist. Depending on the drug used the treatment may comprise medication, behavioural treatments and a combination of both. A substance abuse counsellor will determine the proper course of medical treatment for a patient.

Medications are able to treat addictions to opiates, but they are not effective in treating addiction to stimulants or depressants. In this case behavioural therapy is much more helpful (such as cognitive behavioural therapy, motivational incentives and writings, and group therapy).

Similar to the most chronic illnesses, relapse is a part of the treatment cycle. It doesn’t mean that the treatment was ineffective, but that it should be adjusted or that different ways of treatment should be applied too.
