Research source} Meth is available in white or light brown powdered form, with visible crystals. This drug is most commonly smoked but can also be taken in injection or pill form. Parents and loved ones can recognize the signs of meth use in order to seek immediate help and help loved ones combat drug use. You can recognize the signs of meth use by looking for physical signs, psychological symptoms, and behavioral indications.

Method 1 of 4:

Noticing Physical Signs

1
Search for physical changes. Notice any changes in the person’s physical appearance. Physical signs are very common among people who abuse meth, unlike with other drugs which may have more subtle effects. Use your observation skills. Do you notice anything different about how the person looks? Any physical illness or complaints? Some common physicals signs of meth use are:^{[2]

- Excessive weight loss due to low appetite.
- Dilated pupils.
- Eyes looking droopy, tired, or having dark circles (this can be due to loss of sleep).
- Eye twitching.
2
Look for tooth decay. Meth can adversely affect teeth, turning them brown and causing decay or "meth mouth."^{[4]

Check for track marks or nose bleeds. You will notice track marks on the person's arms if the drug is being injected, or nose bleeds if the drug is being snorted. There may also be burn marks on the person's lips or fingers if the drug is smoked using hot glass or a metallic pipe.^{[6]

4
Pay attention to harsh body odors. If a person is using meth, they will often give off a very bad odor. This is due to a combination of the drug use itself and the person forgetting to wash while they are using. Sometimes the odor is similar to the smell of ammonia.^{[7]

5
Identify signs of premature aging. Meth users often start to look old before their time because their skin is damaged, becoming rough and itchy, and their hair can start to fall out.^{[8]

6
Notice any skin lesions. Skin lesions are very common in meth users due to compulsive scratching at the face.^{[9]
X
Research source}
- Look for open sores on the face.
- Observe if the person picks or scratches at his face.
- The lesions often become infected and result in sores and scars.
7
Identify long-term health issues. Meth users are more prone to diseases, including high blood pressure and heart diseases. They may also pass away at an early age as a result.^{[10]

Search for life disturbances. Social, occupational, and functional disturbances are very common among people who abuse meth.^{[35]
X
Research source} The school/college life, work life and/or social life of people who use meth is impaired. You can detect signs of these disturbances by doing the following:
- Remain in touch with teachers, peers and close friends. They can help you to keep track of the person's recent activities.
- Keep in touch with colleagues, if the person is employed. They can tell you how the person behaves while at work and can fill you in on their daily routine, e.g when they arrive at work, when they leave, etc.
- Observe the legal, social and financial condition of the person who is suspected of being a meth abuser. Poor social functioning, financial trouble and frequent legal issues are commonly the result of meth abuse.^{[36]

Look for signs of impaired thinking. This may show up as reduced cognition or deteriorated memory. Many brain cells are damaged as a result of continuous meth use. This damage is caused by the many caustic chemicals used in meth preparation, and can manifest itself in slower brain function and loss of memory. Look for:^{[37]

Identifying Behavioral Indicators

1
Keep an eye on the activities of the person. The observation of certain activities is very important in identifying the signs of meth abuse. Some common social problems faced by those who abuse meth are:
- Heightened and unsafe sexual activity due to drug effects like confusion and inability to make decisions.^{[43]
  X
  Research source}
- Excessive aggression leading to relationship problems with parents, peers and siblings.^{[44]

- Keeping company with those who either abuse drugs or have easy access to drugs.
2
Notice hyperactivity and impulsivity.^{[45]
X
Research source} Being hyperactive, impulsive, and having low judgment are commonly associated with meth use. Pay attention to the person's behaviors and notice if they are uncharacteristic of the individual.
- Notice excessive talking.^{[46]
  X
  Research source} For example, the person may try to finish others sentences and give advice to others, whether he knows anything about the topic being discussed or not.
- Impulsivity may mean the person behaves recklessly and refuses to worry about the outcomes of his risky behavior.^{[47]

  Research source}
3
Pay attention to financial issues. Meth users often have financial issues due to their drug use. For example, some meth users may spend all of their money to get the drug.^{[48]
X
Research source} Keep in mind that it is often difficult for teenagers, who only get pocket money from their parents, to afford drugs, so they find ways to make up for this shortage of money through various means.^{[49]
X
Research source} Some signs of financial issues are:
- Inability to meet financial needs because of excessive spending on drug related activities like buying drugs or supplying drugs for a party. Notice unpaid bills or not being able to afford normal items like food.
- Excessive debt as a result of asking for money from others in order to finance their drug habit.
- Problems with friends and peers over money issues, due to the drug user's inability to pay back debts.
- Problem with parents and complaints over not having any money.
- Inability to report where the money is being spent when asked.
- Stealing.
4
Pay attention to the company your loved one keeps. Meth users tend to hang around with other people who abuse drugs. This is one of the easiest ways to detect drug abuse. Meth abusers often have the following kind of company:
- People who abuse meth or any other drug.
- People who have easy access to drugs.
- People who don't pose a threat — i.e. those who won't tell the drug user's family or criticize him for his addiction.
5
Be aware of secretive behavior and social isolation. When using, the person may spend the whole day in his room with a closed door, not allowing anyone to enter. Additionally, the person will behave in a very closed off, secretive manner to hide their drug use.^{[50]

6
Look for a meth apparatus in the person's living area. If you find certain drug taking apparatus in the person's headquarters, it is a pretty definite indication that the person is taking meth (or another drug).^{[51]
X
Research source} Items to look out for include:^{[52]
X
Research source}
- The tube of a ballpoint pen or surgical tubing that might have been used to sniff meth.
- A crumpled can of aluminum foil.
- A small bag of white powder or crystals.
- A soda can with a hole on one of its sides.
- A syringe that might be used to inject drugs.

Understanding the Patterns of Meth Users

1
Understand the patterns of low intensity users. These abusers intake meth just to enjoy its so-called benefits, such as feeling energetic, euphoric, experiencing increased alertness and sense of power.^{[53]
X
Research source} They are not psychologically addicted to the drug and they mostly take it by swallowing or snorting it.
- Low intensity users may include truck drivers trying to stay alert while driving long distances, workers trying to stay awake through overnight or taxing shifts, a homemaker trying to juggle housework, raising kids, and trying to be a good or "perfect" spouse.^{[54]
  X
  Research source}
2
Be aware of high intensity abusers. High intensity abusers prefer taking meth by injecting or smoking it.^{[55]
X
Research source} They do so to feel high or aroused. They may become psychologically and physical addicted. They continuously intake large amounts of the drug.
3
Recognize the signs of binge use. Binge abusers need to take more meth every few hours to maintain a high.^{[56]
