Marijuana - (aka dope, pot, weed, grass, reefer)
Marijuana is the most frequently used controlled substance. Most people use marijuana for a relaxant or pain reliever. The user can become so relaxed that their judgment and reflexes are impaired. Effects that can last for hours include: slow physical reflexes/reaction time, reduced coordination, slow mental reflexes, poor concentration, forgetfulness, poor perception of time and space.
Cocaine - (aka coke, C, snow, blow)
Cocaine gives users an energy boost. Smoking cocaine (crack, rock, freebase) produces an intense, brief "high". Cocaine use causes: poor judgment/decision making ability, rushing or inability to concentrate, feelings of superior ability, drastic mood swings, sleeplessness, confusion, paranoia, stroke or fatal heart attack.
Heroin - (aka smack, H, black tar)
People that use heroin use it to get a quick rush followed by a feeling of total relaxation. Heroin (snorted or injected) is very addictive. A user can become addicted after their first use. Heroin can cause: fluctuating alertness and lack of concentration, obsessive focus on their next "fix" - to the extreme that nothing else matters, exposure to HIV and hepatitis from shared needles.
Hallucinogens - (aka LSD/acid, PCP/angel dust, Ecstasy (XTC)/MDMA/Special K, club or rave drugs)
Hallucinogen users use these drugs to experience hallucinations. Hallucinogens cause: bizarre sometimes violent behavior, confusion, loss of concentration, short-term memory, nightmares, fears, paranoia, emotional disturbances sometimes leading to mental breakdowns, panic or depression when drug wears off, flashbacks of hallucinations after drug wears off.
Inhalants - (aka paint thinner, cleaning fluids, laughing gas, aerosols, airplane glue)
These substances are readily available and easily obtainable for users to get "high". Inhalants can cause: slow thinking and reaction time, poor coordination, dizziness, reckless or violent behavior, long-term brain damage, sudden sniffing death syndrome.
Painkillers - (aka opiates or narcotics, such as codeine, morphine, and various prescription drugs)
Prescription strength painkillers can be extremely addictive, causing long-term problems after the initial medical condition is healed. These substances can cause: drowsiness, fatigue, dizziness among other more serious side effects. Added risk of painkiller addiction is the frequency of users who move towards more dangerous drugs such as heroin.
Amphetamines - (aka uppers, speed, crank, ice)
People use amphetamines to lose weight or to have more energy to stay awake. Amphetamines are highly addictive. They stimulate the central nervous system and make users: rush or push beyond normal capacity, careless, anxious and nervous, moody and paranoid. They also cause a 1% loss of brain cells per year.
Sedatives - (aka downers)
People use sedatives or barbiturates such as tranquilizers, sleeping pills and muscle relaxants. These substances can slow and reduce users' physical and mental functions. Many sedative users also use amphetamines to counteract each other.
