When Weed Quits You Before You Quit it: Understanding the Shift in Cannabis Tolerance

December 03, 2023

In the diverse world of cannabis use, it's quite common for individuals to experience a sudden and unexpected shift in their relationship with the herb.

From conversations with numerous cannabis enthusiasts, it's clear that often weed seems to 'quit' the user before they decide to quit it. This intriguing phenomenon, as highlighted by a comprehensive survey of cannabis users, reflects a change in the body's response to cannabis.

It's a normal occurrence, albeit a puzzling one, that leads many to reassess and adapt their usage and understanding of cannabis.

Survey Insights

The survey gathered insights from long-term cannabis users, many of whom expressed a drastic alteration in their reaction to the plant. This unexpected shift often leads users to reconsider their cannabis consumption. Common symptoms prompting this change include:

  1. Increased Anxiety or Paranoia: Users who once found cannabis relaxing suddenly experience heightened feelings of anxiety or paranoia, a stark contrast to the calm it previously induced.

  2. Physical Discomfort: Some report experiencing physical side effects like dizziness, nausea, or headaches, which were not present during earlier usage.

  3. Mental Fog and Impaired Cognition: A noticeable decline in cognitive function, including memory issues and difficulty concentrating, becomes a significant concern for many, affecting their daily functioning.

These symptoms have led several users to significantly lower their usage or stop altogether, highlighting the unpredictable nature of cannabis effects over time.

Potential Explanations

  • Change in Body Chemistry: As we age, undergo medical treatments, or experience hormonal shifts, our body's internal balance changes. These alterations can impact how cannabinoids interact with our system. For instance, aging might reduce our ability to metabolize THC efficiently, leading to different experiences even with the same cannabis product.

  • Tolerance Dynamics: With regular use, the body's cannabinoid receptors may become less responsive to THC, a phenomenon known as tolerance. However, this adaptation can also swing towards heightened sensitivity, where lower THC doses suddenly produce stronger or more adverse effects than previously experienced.

  • Mental Health Factors: Cannabis interacts with neurotransmitters involved in mood regulation. Changes in mental health, such as increased stress, onset of a mental health condition, or even significant life changes, can alter these interactions. This can lead to cannabis exacerbating feelings of anxiety or paranoia instead of providing relief.

  • Variability of Cannabis Products: Different cannabis strains and products have unique cannabinoid and terpene profiles, affecting their impact. Over time, changes in the body's response or variations in the product's composition can turn a previously enjoyable strain into one that causes discomfort or undesirable effects.

  • Lifestyle and Environmental Changes: The context in which cannabis is consumed can significantly affect its impact. Changes in lifestyle, like altered sleep patterns or diet, and environmental factors, such as a more stressful setting or different social surroundings, can influence how the body and mind react to cannabis.

Community Responses

The survey responses provided insightful strategies for those experiencing changes in their reaction to cannabis. Adapting cannabis use to these new sensitivities involves several approaches: 

  • Quitting Altogether: Sometimes, the best course of action might be to quit cannabis use entirely. It could be an opportunity to explore life without being under the influence and to discover new ways of relaxation and enjoyment. Moving on from cannabis can open up different perspectives and experiences in life.

  • Microdosing: Begin with much smaller doses to gauge the body's reaction, allowing for a controlled and gradual experience.

  • Experimenting with Different Forms: Trying out various forms of cannabis, like edibles or tinctures, can offer a different experience. These alternatives, including CBD-rich products, may produce effects that are more manageable.

  • Gradual Reintroduction Post-Break: If cannabis has been paused, reintroduce it slowly. Start with minimal amounts and increase gradually, monitoring the body's response at each step.

  • Changing Consumption Methods: Consider switching to edibles or dry herb vaporizers. These methods can offer a cleaner experience, potentially reducing the likelihood of adverse reactions compared to smoking.

Adhering to these strategies can help maintain a positive relationship with cannabis, even as personal tolerances and reactions evolve.


The experience of cannabis 'quitting' users highlights the dynamic nature of our relationship with this plant. It's a reminder of the importance of being attentive to changes in our bodies and minds and adjusting our cannabis habits as needed. Whether it's modifying the dosage, switching products, or taking a break, flexibility and mindfulness in cannabis use are key to a positive, long-term relationship with this ancient plant.
