We will begin by learning more about the drug. Let’s begin.

What is Marijuana Addiction?

Marijuana is a mind-altering drug with origins from the plant known as cannabis. Users typically dry out and grind the leaves of the plant, and then smoke the dried out and ground leaves using paper and pipe. There are also edible forms of marijuana, such as candies and cookies. They contain the psychoactive ingredient tetrahydrocannabinol (THC).

Some users also consume concentrated doses of marijuana known as “dabs.” Dabs are a resin-like substance or solid, crystallized stuff that contains a high concentration of THC and other cannabinoids. Since they have a high concentration of the psychoactive component of the cannabis plant, dabs produce a more potent effect than other forms of marijuana.

The Endocannabinoid System

A lot of people think that using marijuana doesn’t have adverse effects. But scientific studies reveal that there are risks, especially for teenagers. The drug impairs a person’s judgment and can negatively affect his/her ability to perform tasks such as driving. Regular use of marijuana can also result in poor academic performance or addiction. 

For several decades, researchers have studied the impact of marijuana on the human brain and body. Now, there’s a considerable amount of data that doesn’t only show how the drug works. But they also reveal the vital communication system in the body known as the endocannabinoid system. It is directly affected by the cannabinoids contained in marijuana. 

The knowledge about how marijuana works started in the mid-60s with the identification of delta-9-tetrahydrocannabinol (THC), the psychoactive chemical compound in marijuana. In the 80s, researchers discovered the areas in the human brain and body known as cannabinoid receptors. It is where cannabinoids like THC act. 

Scientists then identified the natural chemicals in the human body (2-arachidonoyl glycerol and anandamide). They also work on the cannabinoid receptors. These natural chemicals and the CB receptors constitute the endocannabinoid system. 

The endocannabinoid system is responsible for many functions of the body. It regulates memory, mood, pain sensation, appetite, and other bodily functions. 

Effects of Marijuana

When you use marijuana, THC reaches the brain quickly and binds into the CB receptors. THC prevents natural cannabinoids in the endocannabinoid system from doing their proper function. It destroys the balance of the whole system. Thus, short- and long-term effects on the brain and body occur.

Addiction to Marijuana

Marijuana is considered an addictive substance under the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition. According to the DSM-5, people who are using the drug can develop a marijuana use disorder. 

The problematic use of marijuana is on the list of diagnosable conditions in the manual. Furthermore, the DSM declares that individuals who regularly use marijuana may start to show similar symptoms and troublesome behaviours observed in other substance use disorders. 

Most individuals who have a cannabis use disorder don’t develop other forms of problematic drug use. However, some of them may get hooked with alcohol, heroin, cocaine, and other addictive substances. 

Marijuana users often get physically dependent on the drug, and they will rely on it to function in their everyday lives. Once they stop taking the drug or decrease the dose, users may begin to feel withdrawal symptoms, such as cravings, difficulty sleeping, loss of appetite, irritability, and anxiety. 

How Addiction Starts

Dependence on marijuana often develops when the user becomes tolerant to the drug. Once tolerance to marijuana develops, the user won’t get the same effects of the same dosage. Thus, he or she will take more doses of the drug to get the feeling of euphoria or high. 

The development of dependence or tolerance to the drug isn’t sufficient to diagnose it as marijuana addiction, however. It’s because not all marijuana users who become tolerant or physically dependent on marijuana will automatically start to take the drug compulsively. However, tolerance and dependence are signs that addiction is already developing. 

One of the most reliable indicators of marijuana addiction is consistent use despite the adverse effects on the person’s health and personal life. The user finds it hard to control his or her marijuana use even though it’s already causing problems. It can be issues such as poor performance in school or work, broken relationships, and issues with the law. 

Current Legal Status of Marijuana

In recent years, we have seen many countries that approve the legalization or decriminalization of marijuana. In some places, the medical use of the drug is legal, while others have both approved the medical and recreational use of the drug. 

Marijuana has some therapeutic benefits, such as reducing pain and stress and treating symptoms of epilepsy. That’s why marijuana advocates have succeeded in encouraging governments in some parts of the world to legalize the drug for medical purposes. For recreational use, marijuana has calming and euphoric effects on users. 

However, despite the drug’s benefits, the risks that come with abusing marijuana are real. Thus, people must read scientific evidence and separate facts from myths that typically surround marijuana use. 

Treatment for Marijuana Addiction

According to research, there’s a significant increase in the number of people seeking treatment for marijuana addiction over the years. Marijuana addiction treatments mostly include therapy and counselling. Here’s the list of treatment options that can help a user recover from marijuana addiction. 

  • Family counselling
  • 12-step community support groups
  • Cognitive-behavioural therapy (individual or group)
  • Motivational enhancement therapy

Although marijuana has some health benefits, marijuana addiction is also real. The drug contains a psychoactive chemical compound known as THC that can cause feelings of euphoria and may lead to addiction. That’s why you should not abuse marijuana. If you think you’re already developing an addiction to it, it’s crucial to seek treatment right away.

Negative Effects of Marijuana

Cannabis, which is more known as marijuana, is a controversial plant these days despite it being with us for thousands of years. Its uses are very well known. Many people are using it for recreation, which often leads to addiction. However, some use it for medical purposes, on which grounds they argue for its legalization. However, in many places, this plant remains illegal, and for a good reason.

Marijuana has many adverse effects, addiction, not least of them. Its recreational use is mind-altering. But in the process, it also affects the users’ bodies in the long run. Let’s look at some of these adverse effects a little further, so that you will know better, thinking twice about using weed.


THC, the main component of marijuana, triggers the brain to release dopamine. It is known as the happy chemical. It’s the reason why many use marijuana and get hooked. However, continued and frequent use of marijuana will alter the brain’s processes, causing its users to be dependent on it. The extent is such that, if a person quits using marijuana after an extended period of its use, the body may react negatively to the withdrawal.

Impaired Thinking

A very common short-term side effect of the drug and the stimulation caused by marijuana often comes to an excess level. Senses can be heightened, inhibitions lowered, and behaviours are altered as well. 

Some users even forget their identity or also assume another while they are using the drug. Indeed, a person who is high because the drug can act very differently. Users can expect this sort of impairment to last for over 48 hours after consumption. Thus, significantly limiting an individual’s cognitive skills in his or her day to day activity. Its use can also cause painful headaches after use, which can further impair the user.

Mental Problems

Related to marijuana use is increased susceptibility to mental problems. The highs produced by marijuana can also cause paranoia, delusions, and psychosis. Psychological issues can include symptoms very similar to schizophrenia, with individuals perceiving smells, tastes, or even objects that are otherwise not there. Severe cases can also contain dangerous panic attacks which could trigger users to erratic and uncontrollable behaviour. 

Long-term use can produce numerous debilitations, and chronic users are at more risk of developing clinical depression. It can also significantly lower IQ, up to a noticeable decline of 8 points if used very early as teenagers.

It can be very devastating for the adolescent population trying to enter higher education or technical fields. Numerous studies point to decreased retention rate in information and difficulty in learning new skills. It’s not surprising to note that chronic marijuana users have an increased rate of financial problems compared to their non-using peers.

Users usually have a harder time forming long-term relationships with increased rates of abuse between partners. Similarly, there is an increased rate of petty criminal behaviours, such as fraud or small-time theft. It is to sustain their lifestyle and addiction. 

Chronic marijuana users are noted as being more likely to be unemployed and on government assistance. As a result, it can lead to a vicious cycle of substance dependency as users seek more marijuana to provide short term relief for their current life situations.

Brain Damage

As previously mentioned, marijuana alters the brain’s processes, causing addiction. But beyond causing dependence, it also makes it harder for the brain to function correctly. Among the possible effects on the brain is lowered IQ. 

If marijuana use started in the adolescent period, the decrease in IQ could be even as high as 8 points. An indicator of further brain damage in this aspect would be increased difficulty than average in motor responses and accomplishing complex tasks.

Respiratory Illnesses

Often, people use marijuana through smoking, similar to tobacco. However, it does not end there, for as per the Alcohol and Drug Abuse Institute, both have the same range of chemicals when smoked. From there, a user is at more risk for respiratory illnesses.

Heart Problems

Marijuana use also increases a person’s heart rate for at least three hours. The heart rate will increase from at least 50 beats per minute to as high as 120 beats per minute. If that wasn’t enough, this could put users at risk of heart attack, and even stroke. A study also found that people who used marijuana had 26% more chances of getting a stroke than people who did not.

Stomach Problems

It almost seems that no organ is safe from the mind-altering effects of marijuana use. And yes, even the stomach is affected as well. Marijuana use alters the appetite of users, leading them to either more hunger or no hunger at all. Nevertheless, the balance of the body is upset in this manner.

There’s more to that though: the risk of contracting Cannabinoid Hyperemesis Syndrome. Sufferers of the disease, caused by long-term use of marijuana, experience recurring cycles of nausea and vomiting. They become dehydrated in the process.

Reproductive Problems

THC also causes, at least in males, the body to produce lower levels of testosterone. Providing lower levels of testosterone usually causes a lessened libido, sluggishness, and yes, even sexual problems. Further, marijuana users are also seven times more likely to contract sexually transmitted diseases than those who don’t. At least one study postulates a possible connection between marijuana and testicular cancer.

Pregnancy Risks

After the discussion about the effects of marijuana on testosterone, let’s discuss the results of the drug on women. Marijuana use for pregnant women increases the risk that their babies will be born underweight or premature. We all know that babies born in those cases are usually susceptible to health problems early on or even later in their lives.

Also, another study has found out that marijuana use not only alters the mother’s brain but also that of the child in her womb. That, at least, puts the child at risk of having problems with brain functions, especially with regards to memory and problem-solving. 

Marijuana can cause a lot of negative effects on your life and in your life. The few negative effects mentioned above are only a few of those negative effects. Keep in mind that even the smallest negative effect of marijuana use can change your life forever. A lot of things can happen to you if you use marijuana. Never forget that there will always be consequences for the actions you take.

Further, it’ll be better for you not to take these drugs since none of these chemicals weren’t meant to be burnt and to be made by your body. The adverse effects of marijuana can seem harmless now. But as you grow older, everything in your life can fall apart. Thus, you should always keep safe and think about the consequences of your actions, especially in taking illicit drugs.
