Crystal meth addiction signs

Some of the first signs of a crystal meth addiction are behavioral changes, which are usually easy to notice. You can usually tell that something is wrong just by observing the person’s behavior. Here are some signs that can signal when someone is struggling with an addiction problem to crystal meth:

  • Becoming secretive and withdrawn.
  • Being caught in lies about everything and nothing.
  • Decreased school or work performance due to crystal meth use.
  • Display of withdrawal symptoms (nausea, dry mouth, sweating, depression, anxiety, shaking, etc.) whenever meth is not around.
  • Getting into legal trouble due to possession or use of crystal meth, or performing other illegal activities to be able to purchase meth.
  • Loss of interest in social life, hobbies, and once enjoyable activities.
  • Staying up for days and then sleeping for a long period of time.
  • Spending a great deal of time hungover and recovering from the effects of crystal meth use.
  • Unable to explain where money (or other possessions) go missing.

If you are looking for the signs of crystal meth addiction in yourself, it may be harder to notice these behavioral changes. You might be in denial about your substance use problem, which is normal because nobody wants to view themselves as an “addict”. But, there are some tell-tale signs that may suggest your use has gotten out of hand and you need to seek medical help.

Clinical signs of addiction

The main signs of an addiction that are used to clinically diagnose a “Substance Use Disorder” include:

Continued Use Despite Negative Consequences = Neglecting work, school, or family obligations because of crystal meth.

Compulsion = Obsessively thinking of using or finding ways to obtain the drug.

Physical Dependence = Feeling a number of physical and/or psychological side effects because of crystal meth.  Experiencing crystal meth withdrawal symptoms when you stop using or significantly reduce regular doses.

Psychological Dependence = Being unable to function ‘normally’ in every day life without crystal meth.

Tolerance = Being unable to feel the wanted effects from crystal meth at lower doses. So, you increase dose amount or frequency to compensate.

Loss of Drug Control = Using crystal meth several times a week. Having a difficulty stopping or controlling crystal meth use once you start. Trying to quit crystal meth but always relapsing. Taking higher doses of crystal meth than you originally plan.

Additionally, crystal meth comes with high levels of drug craving, which can even be physical. However, if you are addicted to meth, there is hope! You need professional help.

Crystal meth addiction symptoms: Can they be treated?

Crystal meth addiction symptoms can be best addressed by a mix of medications, psychotherapy, and behavioral therapies. Sometimes, doctors recommend the short term use of antidepressants to address underlying depression and to help balance serotonin or dopamine levels in the brain. Still, there are no medications demonstrated to be effective for the treatment of crystal meth withdrawal at the moment, though research suggests bupropion and naltrexone have a high potential for addressing crystal meth cravings.

Crystal meth abuse can produce significant psychiatric and medical consequences which need to be medically managed. Cognitive behavioral therapy and contingency management are among the most promising approaches for treatment of crystal meth abuse and dependence. Where can you get the help that you need?

Both inpatient and outpatient rehabilitation programs for crystal meth addiction can be helpful in treating crystal meth addiction. However there are differences in the activities and the structure of each program.

1. Inpatient crystal meth addiction treatment provides 24-7 supervision during withdrawal and early recovery. Treatment programs last 30-60-90 days and can help the body adjust to normal routines. Inpatient treatment tends to be more intense, and allows the patients to access therapy on a daily basis. During treatment, you interact with other patients, consume healthy and recommended food and beverages, and sleep at regular times. Residential addiction rehab takes you out of your normal environment and stress triggers so that you can focus on getting better.

2. Outpatient rehab, on the other hand, allows the person to enroll in daily rehabilitation activities while still living at home and continuing with everyday obligations. you usually visit an outpatient program several times per week over the course of 3-4 months…up to a year or two. While outpatient treatment works for some, it does require high levels of commitment and motivation. Because of the severity of a meth addiction, inpatient centers may be more helpful…at least until your brain and body reach a balance.

  1. 30 year old grandson on pills & meth. He stay gone for days steals everything, losing alot of weight. Won’t bathe hygeine really bad. He’s in denial says he doesn’t need help just don’t want his mother to get a call he’s dead. No private insurance but State insurance. Live in Stockton, CA.

  2. Hi Sara. It can be a slippery slope when you’re in a relationship with a drug user. You’ll need to set you own boundaries and know when it’s time to leave. You can speak with a family counselor to explore this more for yourself…and you can find one here:

    From what we know about meth, it’s very difficult to regulate use…mainly because of the way it works in the brain. Meth is super effective at getting someone high and stays in the system for up to 12 hours. So, in terms of addictiveness …. it’s highly addictive.

    If you think he needs help, please feel free to call us on the number above. We have addiction recovery support specialists on our hotline ready to talk you through treatment options.

  3. When trying to quit meth I notice that I get restless and cannot sit still. I also crave cigarettes non stop though I’m not a smoker. Any tips or wisdom? Are these signs that I’m addicted? Is there anything I can do for these symptoms? They’re affecting my job.

  4. I have been in a relationship with a man who I really care about for a few months. I’m aware that he smokes meth. We have talked opely about it and he claims he isn’t high around me and doesn’t want to be. He says he doesn’t feel the need to be high when we spend time together and that he is using less and less since we’ve been together. Is this possible? I have listened and not judged or asked him to quit.He shows none of the symptoms mentioned except bad teeth. Can he be helped or should I walk away?

  5. It was really informative when you said that there are times when the professionals have to suggest the use of antidepressant to the person in order to balance out the person’s serotonin and dopamine level. Is it safe to assume that one of the contributors to drug abuse is depression? If that is the case, then I guess I have a reason to believe that my boyfriend is abusing drugs. He is clinically depressed after all.

  6. Hi, I’m an addict and would just like to know; a) when detoxing from meth, how long does it take for the meth to be out of your blood system? And if an addict was to detox themselves, approximately how long would it take for the body to be rid of the meth out of your complete body system?

  7. My friend said he is craving meth now he is acting different. With a bad attitude being angry and insulting. What is going on with him? Is it part of the craving???

    1. Hi Rita. It seems to me that your husband is suffering from restless leg syndrome. That’s a neurological disorder in which you feel an uncomfortable sensation in your legs (such as throbbing, pulling or creeping sensations) that is associated with an uncontrollable urge to move them. This syndrome is a common meth withdrawal symptom.
