The younger you are when you start drinking, the greater your chance of becoming addicted to alcohol at some point in your life. More than 4 in 10 people who begin drinking before age 15 eventually become alcoholics.

People who use both alcohol and drugs also are at risk for dangerous interactions between these substances. For example, a person who uses alcohol with depressants, whether these drugs are prescribed or taken illegally, is at increased risk of fatal poisoning.

Hallucinogens
LSD is manufactured from lysergic acid, which is found in ergot, a fungus that grows on rye and other grains.
Source: NIDA InfoFacts: Hallucinogens - LSD, Peyote, Psilocybin, and PCP, 2008 
Originally manufactured as an IV anesthetic in 1950, PCP use in humans was discontinued because of its intensely negative psychological effects.
Source: NIDA InfoFacts: Hallucinogens - LSD, Peyote, Psilocybin, and PCP, 2008 
LSD users can also experience flashbacks, which are when the original drug's effects suddenly reoccur up to a year after the initial use. Because flashbacks can occur without warning, they can cause significant distress or impairment, especially if this occurs in an uncomfortable or dangerous setting such as at work, school, or while driving.
Source: NIDA InfoFacts: Hallucinogens - LSD, Peyote, Psilocybin, and PCP, 2008 
Some LSD users experience severe, terrifying thoughts and feelings of despair, fear of losing control, or fear of insanity and death while using LSD.

PCP is addictive — its repeated abuse can lead to craving and compulsive PCP-seeking behavior, despite severe adverse consequences.

Heroin
PCP is addictive — its repeated abuse can lead to craving and compulsive PCP-seeking behavior, despite severe adverse consequences.

Heroin abuse is associated with serious health conditions including HIV/AIDS and hepatitis, particularly in users who inject the drug.

The alternately awake and drowsy state that heroin users experience while taking the drug is referred to as "on the nod." Mental functioning becomes clouded.

Heroin withdrawal may occur within a few hours after the last time the drug is taken. Symptoms of withdrawal include restlessness, muscle and bone pain, insomnia, diarrhea, vomiting, cold flashes with goose bumps ("cold turkey"), and involuntary leg movements.

Inhalants
Inhalants can kill you the very first time you use them.
Source: SAMHSA Tips for Teens: Inhalants, 2002 
Chemicals like amyl nitrate and isobutyl nitrate ("poppers"), and nitrous oxide ("whippets") are sometimes sold at concerts and dance clubs. They can permanently damage your body and brain even if you try it only one time.

Chronic inhalant abusers may permanently lose the ability to perform everyday functions like walking, talking, and thinking.

"Huffing" concentrated amounts of chemicals from paint and gas can directly induce heart failure and death. Long term effects of chronic abuse include brain, liver, and kidney damage.

Research shows that inhalant use is associated with symptoms of depression. Research has shown that depressed teens are more than three times as likely to start using inhalants than teens with no symptoms of depression.

Meth
Meth can kill you by causing overheating, convulsions, and coma.
Source: NIDA InfoFacts: Methamphetamine, 2008 
Meth users may have cracked or deteriorating teeth that must be extracted. This is often caused by a combination of xerostomia (dry mouth), extended periods of poor oral hygiene, frequent consumption of high calorie, carbonated beverages and tooth grinding and clenching. Some reports have also speculated that the acidic nature of the drug is a contributing factor.

Meth can cause a severe "crash" after the effects wear off.

Prescription Drugs
Unintentional drug poisoning death rates increased substantially in the United States during 1999-2004. This increase can primarily be attributed to increasing numbers of deaths associated with prescription opioids (which are types of painkillers such as OxyContin and Vicodin).
Source: Centers for Disease Control and Prevention. "Unintentional Poisoning Deaths --- United States, 1999 - 2004," 2007. 
More than 29 percent of teens in treatment are dependent on tranquilizers, sedatives, amphetamines, and other stimulants (all types of prescription drugs).

Painkillers, such as Vicodin and OxyContin, are opiates and are very powerful medications that need to be taken under the close supervision of a doctor. These medications, when taken inappropriately, can cause addiction because they impact the same areas of the brain as heroin.

OTC Drugs
At levels above the recommended dosage, DXM (the main ingredient in many cough syrups) is a dangerous dissociative drug like PCP (angel dust) and ketamine (animal tranquilizer).

Some cough syrups that contain DXM often also contain decongestants, which when abused, can cause hypoxic brain damage (not getting enough oxygen to the brain), due to the combination of DXM with decongestants.
Source: NIDA. NIDA InfoFacts: Prescription and Over-the-Counter Medications, 2008.
DXM-based cough remedies contain many other ingredients that, when taken in excessive dosages, can cause serious health effects such as liver damage due to toxic side effects of those other ingredients.

Overdoses of acetaminophen, an analgesic pain killer found in DXM-based remedies, reportedly cause more than 56,000 emergency room visits a year.

Cough syrup is not the only kind of over-the-counter medication (OTC) that is dangerous. Over-the-counter drug abuse also occurs with laxatives, diuretics, emetics, and diet pills, which are abused to lose weight. Ephedrine, caffeine, and phenylpropranolamine are just some of the dangerous substances found in diet pills. All of these substances act as stimulants to the central nervous system and can have serious and potentially fatal side effects.

Rohypnol
Because it has no taste or smell, Rohypnol can be put into your drink without you knowing it.

Rohypnol may cause individuals under the influence of the drug to forget what happened. Other effects include low blood pressure, drowsiness, dizziness, confusion, and upset stomach.

Rohypnol has been used to facilitate date rape. It can be colorless, tasteless, and odorless, and can be added to beverages and ingested unbeknownst to the victim. When mixed with alcohol, Rohypnol can incapacitate victims and prevent them from resisting sexual assault.
