Why Pseudoephedrine is
Misused
Very similar to chemical structure of
amphetamines which is used to make
methamphetamines
Previously easy to obtain; over the
counter
Ways of Obtaining PSE
Smurfing: multiple purchases at one
location
Shelf-Sweeping: theft of all
medications containing
pseudoephedrine from a shelf stock
Shoplifting
Theft from wholesalers

Ways PSE is Misused in The
Manufacture of
Methamphetamines
Made by reduction of PSE
Involves hydrogenation of the hydroxyl
group on the PSE molecule
Most common way is called “Red, White,
and Blue Process” because it involves red
phosphorus, PSE (white), and blue iodine
Increasingly common method is Birch
reduction which uses anhydrous ammonia
and lithium to reduce PSE
Ways to Misuse
Smoking: not really smoking because it is
actually vaporizing to produce fumes. Also
called “Clucking”; fastest and most potent
effect.
Injection: a.k.a. “Slamming”. Biggest Risk-
easier to overdose (anywhere from 125 mg
to 1 gram can fit through a small needle),
infection, skin rashes, and HIV.
Less Common Ways: Snorting, Swallowing,
and Anal Insertion
Effects of Misusing
Immediate Effects: Inc. energy, euphoria, excessive
swelling, loss of appetite, insomnia, agitation,
tremor, panic attacks, inc. libido, dilated pupils,
nausea, diarrhea.
Chronic Use Effects: addiction, weight loss,
withdrawal-related depression, tooth decay (“meth
mouth”), high blood pressure, seizures, skin ulcers,
and amphetamine psychosis (mild craziness)
Tolerance occurs rapidly. Repeated over stimulation
of dopamine receptors cause down regulation of
the receptors.
Dangers of Misusing
Overdose can cause: brain damage,
Meningitis (lead poisoning), meth bugs
( sensation of bugs crawling under the skin),
paranoia, delusions, hallucinations,
Rhabdomyolysis (muscle breakdown), and
death.
Meth labs cause 194 fires, 117 explosions,
and 22 deaths in 2002.
Dump sites cause death in livestock,
contaminated streams, and dead vegetation
Dangers of Misusing
Meth labs cause 194 fires, 117

Ways to Stop PSE From
Being Misused
Many stores and pharmacies have
policies where the drug must be kept
behind a counter, limiting purchase
sales, a minimum age requirement
with identification, and some require a
signature.
