Teen treatment centers have issued a ready- reckoner for parents to understand the various set of symptoms that their children can exhibit when afflicted with alcohol and drug abuse. In fact, it has been that teens today are more aware of the cocktail and combination of drugs that can make even adults gasp in disbelief.  Dual addiction or taking two types of drugs together or mixing drugs with alcohol is a fatal thing that some teens indulge in.  Here are some of the signs and symptoms prevalent in teens according to various types of drugs and alcohol that they indulge in:

1. Alcohol addiction: Symptoms include intoxication, erratic or unstable mannerisms, abusive language being used, mood swings, bloodshot eyes,  foul odor that reeks of alcohol on the body and breath, presence of a different set of friends who tend to be brash with a carefree streak of mind, presence of alcohol bottles hidden in certain places, bottle caps, and behavioral traits like stealing and lying
2. Nicotine addiction. Discolored lips, pale face, dry skin, tobacco smell on the breath, presence of an ash-tray and cigarette butts and ash strewn at certain places in the room.
3. Inhalant addiction: Confused demeanor, mood swings, runny nose and smell of gasoline and such substances in the body.
   1. Cannabinoids: Signs that are associated with Cannabinoid abuse include delirious mindset, fluctuating highs and lows in behavior: euphoria followed by episodes of lethargy, reddish hues in the eye, inability to sleep.
   2. Narcotics: The signs displayed by teens who are addicted to narcotic substances include overexcitement, slowed heart beats and higher tolerance towards pain
   3. Depressants: It has been observed by teen rehab programs that teens that are addicted to depressants have lowered inhibitions, lack of sleep, dizziness, low blood pressure and decreased heart-rate.
   4. Hallucinogens: Teens who are addicted to hallucinogens have problems with their sleep, their vision tends to be blurred at times; they are paranoid and they are not able to be in sync with their emotions.
   5. Cold medications: Teens who are addicted to cold medications, an infamous form of prescription drug addition, tend to show signs that include inability to sleep, anxious behavior and rapid heartbeats.
   6. Dissociative Addiction: Those who abuse dissociative anesthetics suffer from increased heart rate, memory loss, aggressive behavior, mood swings, high blood pressure and even vomiting.
   7. Ecstasy: Teen treatment centers have seen that cases of those who are admitted to Ecstasy and such types of club drugs usually tend to be euphoric with an inability to sweat, memory loss, fluctuating heart beats and being overtly promiscuous.

All of these signs and symptoms that are typical of different types of teen substance abuse also have uncomfortable withdrawal symptoms when these drugs are denied.  It is the responsibility of the elders to see to it that teens are not coerced or induced in substance abuse because not only cause various health complications but they can also result in crimes like  thefts, robbery, molestation, rapes and homicides.
