respiratory depressants

17
Q

symptoms of opioid withdrawal

A

dysphoria and depression
anxiety and fearfulness

restlessness and yawning
vomiting
pain and aching
diarrhea (can be fatal in newborns born to dependent mothers)
craving

18
Q

what are the differences between cocaine and meth?

A

cocaine is a purified product of the coca plant; meth can be made in a lab fairly easily
cocaine blocks dopamine reuptake; meth forces the release of dopamine
meth is used to treat ADHD

19
Q

how do opiates block pain by preventing pain information from arriving at the brain?

A

Analgesic effects caused by opiates are mediated by nociceptive neurons, which carry pain information away from the site of injury to the spinal cord where they synapse onto pain pathways. The neurotransmitters at the synapse contain a peptide called Substance P and glutamate. opiates inhibit Substance P and prevent them from sending the pain information to the brain. opiates increase the activity of descending pathways

20
Q

what is the mechanism of action of disulfiram (Antabuse) and what is the outcome of drinking after

A

if a person does not manufacture sufficient aldehyde dehydrogenase, they will experience acetaldehyde buildup, which results in nausea, headache, and flushing. antabuse is designed to produce this reaction in combination with alcohol to discourage consumption.

21
Q

why was THC’s medical use hampered?

A

the quantity of THC in medical preparations was variable

22
Q

what does “pyramid of prejudice” refer to?

A

Anslinger’s technique of getting lucid drug stories into print, then citing it as factual evidence of drug abuse

23
Q

what system does LSD and psilocybin affect?

A

serotonin systems

24
Q

what hallucinogen produces more disassociation than others?

A

PCP

25
Q

MAO-Inhibitors

A

destroy the enzyme that breaks down serotonin, dopamine, and norepinephrine

26
Q

what do convention antipsychotics treat?

A

hallucinations and delusions

27
Q

what can risperidone be used for?

A

calm people with dementia

28
Q

what is the difference between clinical and statistical significance?

A

clinical significance shows whether something has a real genuine, palpable, noticeable effect on daily life. statistical significance shows whether there is an effect in number based on studies, but correlation does not necessarily mean causation.

29
Q

what are the implications of THC being fat-soluble?

A

enters the brain quickly, faster and complete onset
stored in fat then released slowly, withdrawal syndrome is muted
drug test can be positive for some time
