Stimulant Use Disorder:
Substance use disorder involves any of the classes of drugs that include cocaine, methamphetamine and prescription stimulants. Higher addiction levels affect the central nervous system and are more potent.

– Initial outcomes (euphoria, an increase in energy, attention, wakefulness, self-confidence and sexuality, a decrease in appetite)
– – Risks of infectious diseases such as HIV and Hepatitis B and C (risky sexual behaviour, unsafe injection practices)
– A long-term misuse of MA may cause many problems, including weight loss, tooth problems (bruxism, dry mouth, poor oral hygiene), and sexual dysfunction.
– Weight loss – Severe dental problem (due to bruxism, dry mouth, poor oral hygiene)
– Cognitive problems/
– Psychosis, violent behaviour
– OD: hyperthermia, convulsions, arrhythmia, stroke, death
– In the 1980s, MA use increased due to production in clandestine labs. In 2005, Congress passed the Combat Methamphetamine Epidemic Act, regulating the precursor chemicals (ephedrine and pseudoephedrine) used in the production of MA. How much of the US MA supply is from the outside.
- – Cocaine is plant-based.
- – Cocaine preparations vary in potency (e.g. coca leaves, coca paste, cocaine hydrochloride, and cocaine alkaloids such as freebase and crack)
- – Is used as an anesthetic in ENT surgeries and to limit bleeding. .
- – Similar desirable effect as MA (increase in energy and sexuality, decrease in appetite and euphoria)
- – Risk of cardiac problems such as MI and arrhythmia
- – OD: seizures, cardiac arrhythmias, respiratory failures, stroke
- – Salt (most commonly hydrochloride salt)
- – Base form (not neutralized by an acid to make salt)
- -Prescription stimulants include medications such as amphetamine and dextroamphetamine (Adderall and Dexedrine) and methylphenidate (Ritalin, Concerta).

- – Regional variability: highest in the western and midwestern regions
- – In 2018, 977,000 people aged >12 had a cocaine use disorder up from 867,000 in 2016. (SAMSHA)
- – An estimated 561,000 people aged >12 had a prescription stimulant use disorder similar in the past year. (SASHA)
