Could Your Marijuana Habit Lead to Cannabis Use Disorder?

Cannabis goes by many names: pot, marijuana and weed, to name a few. No matter what you call it, it’s the most commonly used federally illegal drug in America, according to the Centers for Disease Control and Prevention. While using weed is unlikely to lead to a fatal overdose, you may develop a cannabis use disorder. 

“Use weed a lot, and your body becomes physically dependent on it,” says Dr. Beverly Shin, clinical assistant professor of psychiatry at Weill Cornell Medicine. “If you take it away and your brain reacts badly, that’s when we say you have a cannabis dependence.” 

How Cannabis Works 

Taken from the marijuana plant, cannabis can be used in many ways. It’s often rolled up into a joint and smoked like a cigarette or cigar, but it can also be smoked in a pipe or even vaped. Some people mix it into food or brew it into tea. 

Whether smoked, eaten or drunk, marijuana can get you high. When in this state, you may feel relaxed and suddenly hungry. These benefits are reasons some use medical marijuana. However, marijuana use can lead to difficulty with the following: 

  • Memory 
  • Movement 
  • Problem-solving  
  • Thinking 

Use large amounts of weed or high-potency cannabis, and you may also deal with other side effects, such as hallucinations, panic, fear or anxiety. All of these mind-altering effects are due to chemical compounds found in marijuana.  

“Cannabidiol (CBD) and tetrahydrocannabinol (THC) get a lot of airplay,” Dr. Shin says, “but there are many potentially psychoactive compounds inside the cannabis plant. They're not all thought to be psychoactive, but it's possible that all of them work together.” 

Effects of Long-Term Cannabis Use 

As pleasurable as getting high may be, that high comes at a cost. In addition to the side effects mentioned above, frequent cannabis use can have long-term effects that include physical and psychiatric problems. 

These include: 

  • Cardiovascular diseaseSome research shows an association between frequent use of marijuana and increased risk of heart attack and stroke.
  • Decreased athleticism. Marijuana use affects your movement, coordination and timing, all of which are vital on the court or field. 
  • Possible mental health risk. It’s unclear whether marijuana use leads to anxiety, depression and other mental health issues, but many users experience these conditions.  
  • Lost IQ. Using weed at an early age can reduce your brain power. Once you drop IQ, there is no way to raise it again. 
  • Lung problems. “We have robust tobacco studies showing how carcinogenic cigarettes are, but we don’t have that for cannabis,” Dr. Shin says. “That said, anytime you burn stuff and inhale it, it’s probably going to hurt your lungs.”
  • Reduced driving skills. Driving with cannabis in your system may make you a more dangerous driver. Your reaction time can slow, you have a hard time responding to signals and sounds, and you are less coordinated. 

An additional problem faced by weed users is developing a substance use disorder. The Substance Abuse and Mental Health Services Administration found that approximately 10 percent of those who smoke cannabis or use weed in other ways develop cannabis use disorder. Users who start before age 18 are at even higher risk of developing marijuana addiction.  

Defining Cannabis Use Disorder 

With so many potential health problems, it’s important to recognize and treat cannabis use disorder. Those experiencing this condition may have the following symptoms: 

  • Attempting to quit but failing 
  • Craving the drug 
  • Experiencing withdrawal symptoms when attempting to quit 
  • Needing more weed to get high after developing a tolerance to marijuana  
  • Spending a lot of time using marijuana  
  • Preferring to use cannabis over participating in once-enjoyed activities  

To determine if your marijuana use is affecting your life negatively, Dr. Shin offers a way to self-diagnose. Ask yourself these questions: 

  • Am I engaging in work or school the way I desire? 
  • Am I engaging with loved ones the way I want? 
  • Am I enjoying life? 
  • Am I doing things every day that are important to who I am as a person? 

“If the answer to these questions is no and weed is causing you to miss out on life or not feel well,” Dr. Shin says, “it’s worth considering whether you have cannabis use disorder.” 

Overcoming Cannabis Use Disorder 

When marijuana use becomes more than an occasional habit, you may need professional help to recover. While there is currently no approved medication for cannabis use disorder, available treatment options include the following: 

  • Cognitive behavioral therapy. A trained mental health professional helps you identify triggers that lead to marijuana use. Then you work to retrain your brain and emotions so you can face those triggers without using pot. 
  • Motivational enhancement therapy. You set goals and make plans to reach those goals in a supportive, nonjudgmental environment. 

A good first step toward recovery is to visit the Weill Cornell Medicine Support, Advocacy and Family Education (SAFE) program. Directed by Dr. Evguenia Makovkina and Dr. Nicholas A. Romano, the program provides education and resources for improved health, all while treating you as you want to be treated. 

“When a person is in a substance abuse cycle, it can be really uncomfortable to break that cycle,” Dr. Shin says. “They need a lot of support, which we’re here to provide.” 

Conclusion 

Marijuana is the most used federally illegal drug in America. Use it too much, and you may wind up with a variety of health issues, including cannabis use disorder. 

  • Chemicals inside marijuana promote intoxication. Short-term negative effects may include difficulty thinking and moving. Use a lot at once, and you may experience hallucinations and other mental health issues. 
  • Using weed regularly over time can put your heart, mental health, lungs and more at risk for serious complications. 
  • If you experience cannabis use disorder, you might spend a lot of time using marijuana and have tried to quit without success. Professional help can help you achieve sobriety.
