What Does Methamphetamine Intoxication Look Like?

By  Zawn Villines
A person's behavior may be the earliest sign of a meth addiction. Here are symptoms to be aware of.

Methamphetamine is a powerful stimulant that makes you feel euphoric, energetic, and powerful. These enticing feelings convince many users to keep abusing meth, leading to an addiction. 

“Meth can cause physical and psychological dependence, and also increased tolerance. To overcome this tolerance, methamphetamine users frequently need to increase the dose to get to the satisfying high,” Rashmi Byakodi, BDS, tells WebMD Connect to Care.

Methamphetamine intoxication looks different in each person, but users often seem agitated, aggressive, or very high energy. It isn't possible to tell which drug a person is using based on symptoms alone, but here are some signs of meth use. 

What Meth Intoxication Looks Like

A person could show any of these symptoms while high on meth

  • High energy 
  • Increased attention. They might hyper-focus on seemingly irrelevant or random details. 
  • Excessive talking. They might not recognize normal social cues, causing them to talk for long periods of time or to ignore signs that people are bored. 
  • Aggression 
  • Euphoria and intense feelings of pleasure 
  • Increased interest in sex 
  • Less need to sleep 
  • Psychosis. They may have delusions, hallucinations, unusual beliefs, or seem disconnected from reality. 
  • Low appetite 
  • Rapid heart rate or breathing 
  • A high body temperature. They may sweat or complain of being hot. 

Byakodi cautions that meth overdose is common, especially as users chase the high they got with their first few doses. Meth toxicity is an extreme form of meth intoxication that happens when you take enough meth to damage your brain or other organs, potentially causing an overdose. 

“Patients with meth toxicity show altered mental status, agitation, suicidal tendencies, and sometimes coma and seizures,” she says. 

Meth Use Symptoms

Prolonged use of meth can bring on a number of symptoms that may be visible even when you’re not high. They include

  • Sores from picking the skin 
  • Meth mouth, which happens when gum disease and tooth decay cause someone to lose or break teeth, or to develop bleeding gums 
  • Weight loss 
  • Changes in mood or mental health 
  • Loss of interest in hobbies 
  • Financial or legal problems 
  • Stealing to get money for meth 
  • Ignoring loved ones, children, or friends
