Bad drugs include illegal substances or those that are being illegally distributed. These drugs carry the potential for addiction and pose safety and legal concerns in society. They include cocaine, heroin and steroids.
Cocaine
According to Narconon, cocaine is a drug that affects the central nervous system. It causes a buildup of dopamine, which produces recurrent stimulation of certain neurons that results in feelings of euphoria.
Individuals who use cocaine experience euphoric symptoms such as hyperstimulation and reduced fatigue. They may have dilated pupils and an increase in heart rate. Cocaine is snorted, ingested or injected and can detrimentally affect the heart and cause death. The effects of the drug last for 15 to 30 minutes.
Heroin
Heroin is a highly addictive opiate. It works by converting to morphine in the brain and binding to opoid receptors. This causes a rush, mental clouding or confusion. More than 750,000 persons in the U.S. are believed to be addicted to heroin. The drug can be snorted, injected or smoked.
Heroin is being used in more affluent communities, according to Narconon. Since heroin's street potency varies, the potential for overdose and death is high.
Steroids
Steroids are similar to the male sex hormone testosterone. They cause an increase in “male” characteristics such as enhanced athletic performance and larger muscles. Steroids are injected or taken in pill form.
Steroids are dangerous because they can cause liver problems, high blood pressure, shrinking of the testicles, prostate cancer or mental problems such as depression. In addition, they can impair regular growth in adolescents.
Marijuana
According to HelpGuide.org, marijuana enhances the senses and promotes the feeling of overall well-being. Marijuana increases the heart rate and can cause bloodshot eyes. Smoking marijuana can cause irritation or damage to the lungs.
Marijuana is used medicinally for some conditions since it can decrease nausea and vomiting, relieve pain or stimulate the appetite. If abused, marijuana can lead to problems in school or work and relationships. Long-term use can cause an individual to become slow and inattentive. When one stops smoking marijuana after using it for a period of time, anxiety and irritability can occur.
