perform tasks requiring concentration and coordination, such as driving a car.
Research also shows that students do not retain knowledge when they are
“high.” Motivation and cognition may be altered. Marijuana can also
produce paranoia and psychosis. Marijuana smoke contains more cancer-
causing agents than tobacco smoke and is damaging to the lungs and
pulmonary system. Long-term users of cannabis may develop psychological
dependence and require more of the drug to get the same effect. The drug
can become the center of their lives. It is anyone’s guess what ingredients
may be in synthetic marijuana or other synthetic products.
3. Narcotics (Fentanyl, Heroin, Methadone, Codeine, Morphine, Meperidine,
Opium, Percocet, Percodan, etc.) initially produce a feeling of euphoria that
often is followed by drowsiness, nausea, and vomiting. Users also may
experience constricted pupils, watery eyes, and itching. An overdose may
produce slow and shallow breathing, clammy skin, convulsions, coma, and
possible death. Tolerance to narcotics develops rapidly and dependence is
likely. The use of contaminated syringes may result in disease such as AIDS,
endocarditis, and hepatitis. Addiction in pregnant women can lead to
premature, stillborn, or addicted infants who experience severe withdrawal
symptoms.
4. Hallucinogens (such as PCP, LSD, Mushrooms, Ecstasy, Ketamine, etc) have
mind-altering effects. Perception and cognition are impaired and muscular
coordination decreases. Speech may be blocked and incoherent. Chronic
users of PCP may have memory problems and speech difficulties lasting 6
months to a year after prolonged daily use. Depression, anxiety, and violent
behavior also occur. High psychological dependence on the drug may result
in taking large doses of PCP. Large doses produce convulsions, comas, and
heart and lung failure. Lysergic acid dyethylamide (L.S.D. or "acid"),
mescaline and psilocybin (mushrooms) cause illusions, hallucinations and
altered perception of time and space. Physical effects include dilated pupils,
elevated body temperature, increased heart rate and blood pressure, decreased
appetite, insomnia and tremors. Psychological reactions include panic,
confusion, paranoia, anxiety and loss of control. Flashbacks, or delayed
effects, can occur even after use has ceased.
5. Stimulants (Amphetamines, Methamphetamines, Adderall, Ritalin, Cocaine,
Crack, etc.) can cause increased heart and respiratory rates, elevated blood
pressure, dilated pupils, and decreased appetite. In addition, users may
experience sweating, headache, blurred vision, dizziness, sleeplessness, and
anxiety. Extremely high doses can cause a rapid or irregular heartbeat,
tremors, loss of coordination, and even physical collapse or death. An
amphetamine injection creates a sudden increase in blood pressure that can
result in stroke, very high fever, or heart failure. Users report feeling restless,
anxious, and moody. Higher doses intensify the effects. Persons who use
large amounts of amphetamines over a long period of time can develop an
amphetamine psychosis that includes hallucinations, delusions, and paranoia.
These symptoms usually disappear when drug use ceases. Many stimulants
are extremely addictive.
