Neurochemical Mechanisms & Other

Question 1

Amphetamines

Answer 1

Facilitates release of dopamine and norepinephrine inhibitng reuptake

Question 2

Benzodiazepines

Depressant

Answer 2

Facilitates binding process of GABA to norepinephrine

Question 3

Methylphenidate

Answer 3

Action on dopamine reuptake inhibitor

Question 4

Scopolamine

Answer 4

Blocking Acetylcholine Receptors

Question 5

Caffeine

Answer 5

Blocks adenosine receptors.
Adenosine is inhibitory to primarily acetylcholine and dopamine
Affects the cortex
Increases glucose in cells

Question 6

Volatile Organic Ingredients

Answer 6

Expand neuronal cell membranes causing disturbances in Na and K channels making a less excitable cell

Question 7

Ethyl

Answer 7

1. Inhibit glutamate
2. Enhance Gaba

• Glutamate is excitatory
• Gaba is inhibitory

Question 8

Salvia

Answer 8

Activator of Kappa opioid receptors

Question 9

Barbiturates

Depressant

Answer 9

Reduce glutamate and increase affinity of Gaba
(Depresses RAS at low doses and depressed CNS at high doses)

Question 10

Psilocybin

Answer 10

Agonist of several serotonin receptors

Question 11

Why do females have a higher BAC than men

Answer 11

• Smaller size
• Less alcohol dehydrogenase
• Contraceptives slow drug metabolism
• Males have a higher water content

Question 12

What causes hangovers?

Answer 12

• Dehydration
• Congeners
• Withdrawal

Question 13

Nicotine

Answer 13

Stimulates nicotine subtype of acetylcholine receptors by mimicking acetylcholine
