Bath salts & plant food Flashcards
what kind of drug are bath salts (depressants or stimulating)
stimulant
why have bath salts become popular
they are alternatives to drugs like cocaine and MDMA
what is the deal with MDPV
it is a kind of bath salt that caused 100+ deaths
is there only 1 type of bath salts (explain)
no, the types in circulation change over time (as one becomes illegal, a new type emerges)
has there been clinical testing on bath salts
no
what is the reputation of bath salts
dangerous drugs that can harm or kill the user
what is cathinone
naturally occurring drug found in the plant khat
why is khat illegal in many countries
it is used as a stimulant and has caused many hospitlizations
what are synthetic cathinones
a khat derivative
what is mephedrone
one of the first reported components of bath salts
what is another name for 4-methylmethcathinone
mephedrone
why were synthetic cathinones first made
because khat has become illegal (it contains the stimulant cathinone)

stimulating
what are beta ketonated amphetamines
cathionone and its derivative
what do you call cathionone and its derivatives
beta ketonated amphetamines
what is the difference with cathionine and amphetamine (structure)
just a ketone group
how does the polarity of cathionone compare to amphetamines +why
more polar because of the ketone
what is mephedrone (compared to cathionone)
semi-synthetic derived from cathionone
which was the first bath salt that became popular
mephedrone
what are the 3 most popular bath salts
mephedrone, methylone, MDPV
how does the ability of of cathionone to cross the BBB compare to amphetamines +why
it is slower (because more polar from ketone)

what do differences in CYP2D6 genes link to
different levels of psychoactive effects and dependence risk of dextromethrophan
what does a decreased metabolism of dextromethrophan by CYP2D6 do to euphoria (why)
less euphoria

brain dysfunction
such as increased impulsivity
what happens to adolescents that use dextromethrophan and why (2 things and what causes that)
inhibits neuronal pruning, so bigger volume and more dysfunction (such as increased impulsivity)
are dextromethrophan more or less impulsive
more
