Cannabis and ADHD: Understanding the Complex Relationship and Exploring Treatment

Cannabis has gained attention as a potential treatment option for various mental health conditions, including attention-deficit/hyperactivity disorder (ADHD). However, the use of cannabis for ADHD remains a topic of debate due to limited research and the potential for both benefits and complications. In this article, we will delve into the relationship between ADHD and cannabis, examine the existing evidence, and provide advice for adults seeking alternative treatment options.
Understanding ADHD:
ADHD is a mental health condition characterized by inattention, hyperactivity, and impulsivity, which can significantly impact daily functioning. The symptoms of ADHD can manifest in different patterns, including inattention, hyperactivity, and impulsivity, or a combination of these. Let's explore each pattern in more detail:
Inattention: Individuals with this pattern struggle with maintaining focus, organization, and task completion. Symptoms may include appearing inattentive when spoken to, difficulty following instructions, and forgetfulness in daily activities.
Hyperactivity and Impulsivity: Hyperactivity involves excessive movement, even in inappropriate situations, while impulsivity is characterized by acting without thought or self-control. Symptoms may include constant restlessness, difficulty waiting for one's turn, and interrupting others.

The Complex Relationship Between Cannabis and ADHD:
The common perception that cannabis can help alleviate hyperactivity and provide relief for ADHD symptoms is oversimplified. While cannabis use is prevalent among individuals with ADHD, research suggests that it may lead to the development of a cannabis use disorder. Moreover, cannabis affects brain areas that are already impacted by ADHD, potentially causing short-term improvement in symptoms. However, the long-term effects of cannabis on ADHD remain unclear, and the lack of evidence suggests that it may do more harm than good.
Potential Harmful Effects of Cannabis on ADHD:
When consumed, cannabis inhibits neuronal connections in the brain, resulting in slower signaling processes. Additionally, it influences the brain's dendrite structure, which is essential for control processes, learning, and overall brain health. Given that individuals with ADHD already experience inhibitions in these areas, both short-term and long-term cannabis use may lead to complications such as motivation issues, memory impairment (particularly in individuals under 25), anxiety, depression, language and learning disabilities, and even mood disorders.
Cannabis and ADHD Medication:
Considering that many individuals with ADHD are on medication, it is crucial to understand the potential interactions between ADHD medication and cannabis. THC, the psychoactive compound in cannabis, affects the same brain chemicals targeted by ADHD medication, potentially hindering the medication's effectiveness. However, ADHD medication itself can come with unwanted side effects, which may be alleviated by cannabis. Finding the right balance between medication and cannabis use is challenging due to the limited research available on this topic.
Examining the Research: Research on the relationship between cannabis and ADHD is currently limited, but a few studies shed some light on the subject:
A 2016 report analysed self-reports from individuals with ADHD who used cannabis, with 25% reporting some therapeutic effects, 8% reporting negative effects, 5% experiencing both positive and negative effects, and 2% perceiving no effects.
2022 study involving three patients with ADHD found that the addition of cannabis to their treatment regimen improved symptoms, quality of life, emotional regulation, and job performance.
A 2021 survey of 1,738 students suggested that cannabis may alleviate side effects experienced by those taking ADHD medication. However, large-scale clinical studies on CBD, another component of cannabis, and ADHD symptoms are still lacking.

The Bottom Line: Cannabis as an Effective Treatment for ADHD: While there is some evidence suggesting that cannabis can provide temporary relief for certain aspects of ADHD, it is unlikely to be an effective long-term treatment option. The potential negative effects of cannabis on individuals with ADHD outweigh the positive ones. However, it is important to note that recreational cannabis use in moderation may have minimal impact on individuals with ADHD. If considering cannabis as a treatment option, consulting a healthcare professional is highly recommended to gain a comprehensive understanding of its potential benefits and risks based on individual circumstances.
Final Thoughts:
The relationship between cannabis and ADHD is multifaceted, with limited research and conflicting evidence. While cannabis may offer temporary relief for certain symptoms, its long-term use may lead to additional complications. Individuals with ADHD should exercise caution when considering cannabis as a treatment option and consult with a healthcare professional for personalized advice. More research is needed to gain a better understanding of the effects of cannabis on ADHD and to explore alternative treatment options that provide long-term benefits without the associated risks.
