Methamphetamine Purity 99%

What is Methamphetamine?

Methamphetamine is a synthetic stimulant drug belonging to the amphetamine class. It is chemically similar to amphetamine but has greater potency and longer duration of action. Methamphetamine activates the sympathetic nervous system and produces intense euphoria, increased energy, and heightened alertness.

Very Limited Medical Use (Desoxyn):

Methamphetamine has one FDA-approved medical use:

• Desoxyn (methamphetamine hydrochloride tablets): Rarely prescribed for severe ADHD (Attention Deficit Hyperactivity Disorder) when other treatments have failed

IMPORTANT: Desoxyn is rarely prescribed (less than 0.01% of ADHD prescriptions). The vast majority of methamphetamine use is illicit. Medical methamphetamine is never available in retail pharmacy settings for outpatient dispensing without strict DEA controls.

How Methamphetamine Works (Mechanism of Action):

Methamphetamine is a powerful monoamine releaser that floods the brain with three key neurotransmitters:

Unlike cocaine (which blocks reuptake), methamphetamine causes neurons to release large amounts of these neurotransmitters AND blocks their reuptake — resulting in a more prolonged and intense effect.

Immediate Physical Effects:

• Extreme increase in heart rate and blood pressure

• Rapid breathing

• Dilated pupils

• Decreased appetite

• Increased body temperature (hyperthermia)

• Sweating and dry mouth

• Tremors and muscle twitching

• Teeth grinding (bruxism)

• Reduced need for sleep

Immediate Psychological Effects:

• Intense euphoria (“rush”)

• Increased energy and activity

• Heightened alertness and focus

• Grandiosity and overconfidence

• Increased libido

• Anxiety and irritability

• Paranoia

• Aggressive or violent behavior

• Psychosis (at high doses)

Short-Term Health Risks:

Long-Term Health Consequences:

Methamphetamine-Induced Psychosis:

Chronic use can cause psychotic symptoms that may persist for months or years after stopping use:

Overdose Signs:

Overdose Response:

• Call 911 or local emergency services immediately

• Try to keep the person calm and cool (apply cool compresses, remove excess clothing)

• Do not restrain forcefully unless danger to self/others

• Do not give anything by mouth if unconscious or seizing

• If unknown substance (possible opioid/fentanyl), administer naloxone — it won’t reverse meth but may reverse opioids

• Provide emergency responders with information about what was taken (if known)

Where to Get Help for Substance Use:

Key Educational Message:

Methamphetamine is one of the most dangerous and addictive illicit substances. Chronic use leads to severe physical deterioration (meth mouth, skin sores, weight loss), permanent brain damage, psychosis, and death. There is no safe dose of illicit methamphetamine. Fentanyl contamination is increasingly common. If you or someone you know is using methamphetamine, seek professional help. Recovery is possible with evidence-based treatment including cognitive-behavioral therapy and contingency management. There are no FDA-approved medications for methamphetamine use disorder at this time.
