Drugs affect a person mentally and physically depending on the drug type. While basically, drugs can be categorised as Uppers, Downers, All Rounders and Inhalents, the speed with which a drug takes effect depends on the mode of intake. This could be oral, nasal (snorting/inhalation) or by injection.
The body considers any drug a poison. Drug use over a long period of time forces the body to change and adapt. With time, more and more of a drug needs to be taken to achieve the same effect. The body begins to tolerate the drug Inverse tolerance occurs when a person becomes more sensitive to the effects of the drug as the brain chemistry changes. In reverse tolerance, initially, an individual becomes less sensitive to a drug, but as it destroys certain tissues and/or as an individual becomes older, the trend is suddenly reversed and he/she becomes more sensitive. This is particularly true in alcoholics when, as the liver is destroyed, it loses its ability to metabolize the drug. Alcohol or other drugs used in combination with prescription drugs, are a virtual time bomb, waiting to explode. Alcohol and other drugs greatly minimize the effectiveness of the prescription drugs. They may also completely take away their effect, requiring a higher dose of the medications than would otherwise be necessary. All psychiatric symptoms especially suicide, depression, paranoia, anxiety agitation, mania and sleeplessness are also greatly magnified if drugs/alcohol are used in combination with prescription drugs. In addition, they often precipitate psychiatric hospitalization. Therefore, if you are under medication never mix them with street drugs or alcohol. Take them only as prescribed. Speak to the doctor before altering the dosage or combination yourself.
