1. Due to the significant differences in the amount and composition of active compounds found in hallucinogens, particularly in those derived from plants and mushrooms, the effects of hallucinogens are highly:
A. Precarious and ambiguous
B. Complex and fallible
C. Variable and unreliable
D. Divergent and convoluted
2. LSD, peyote, psilocybin, and PCP are drugs that cause profound distortions in a person’s sense of reality, and LSD, PCP, and psilocybin cause their effects by initially disrupting the interaction of sensory neurons and the neurotransmitter dopamine.
A. True
B. False
3. Each of the following is an accurate statement about the adverse health effects of hallucinogens EXCEPT:
A. The effects of LSD which may include dilated pupils, increased body temperature, heart rate, and blood pressure, profuse sweating, loss of appetite, sleeplessness, dry mouth, and tremors, depend largely on the amount taken
B. Psilocybin can produce muscle relaxation or weakness, ataxia, excessive pupil dilation, nausea, vomiting, and drowsiness, and individuals who abuse psilocybin mushrooms also risk poisoning if toxic mushrooms are incorrectly identified
C. Physiological effects of low doses of PCP include a slight increase in breathing rate, a pronounced rise in blood pressure and pulse rate, shallow breathing, flushing and profuse sweating, and at high doses, blood pressure, pulse rate, and respiration drop, and nausea, vomiting, blurred vision, loss of balance, and dizziness may occur
D. Peyote effects can be similar to those of psilocybin, including muscle weakness, excessive pupil dilation, nausea, vomiting, and drowsiness, and it may also cause preterm labor and premature delivery in pregnant women
4. Gamma hydroxybutyrate (GHB), Rohypnol, ketamine, as well as MDMA (ecstasy) and methamphetamine are considered club drugs, which are a pharmacologically heterogeneous group of psychoactive drugs that tend to be abused by teens and young adults at bars, nightclubs, concerts, and parties.
A. True
B. False
5. Although it is often extremely difficult to determine toxicity and associated medical consequences of club drugs, some known risks are that coma and seizures can occur following use of GHB, Rohypnol may be lethal when mixed with alcohol and/or other CNS depressants, and ketamine, in high doses, can cause:
A. Uncoordinated movements, profound sweating, and nausea
B. Impaired motor function, high blood pressure and potentially fatal respiratory problems
C. Anxiety, confusion, and depression
D. Blurred vision, faintness, and chills
6. The effects of MDMA last approximately 3 to 6 hours, although it is not uncommon for users to take a second dose of the drug as the effects of the first dose begin to fade, or to use it in combination with other drugs.
A. True
B. False
