Cannabis contains over 100 cannabinoids, including THC (tetrahydrocannabinol) and CBD (cannabidiol). Both CBD and THC interact with the endocannabinoid system (ECS), crucial in regulating physiological processes, including appetite, pain, mood, and immune function. This article will explore the concept of tolerance and how it affects the ECS in relation to certain cannabis strains.
What is Cannabis Tolerance?
Cannabis tolerance refers to how your body gets accustomed to cannabis, which can lead to weaker effects. This happens because THC turns on CB1 cannabinoid receptors in the brain. Moreover, chronic use of high THC strains can lead to the development of dependence and withdrawal symptoms upon cessation, which may further dysregulate the ECS.
Factors Influencing Tolerance Development
Tolerance to cannabis can develop due to various factors, including frequency and dosage of use, potency, and composition of the strain, individual characteristics of the user, and other environmental and lifestyle factors. Below are some of the factors that may influence the development of tolerance:
1. Frequency and dosage of use
Repeated use of cannabis can lead to the development of tolerance, as the body becomes accustomed to the presence of the drug and adjusts its response accordingly. Higher doses of cannabis can also lead to more significant changes in the ECS and a greater likelihood of tolerance development.
2. Potency and composition of the strain
High THC strains are more likely to lead to the development of tolerance and dysregulation of the ECS than low THC strains or those with a balanced ratio of THC and CBD. In addition, other cannabinoids and terpenes can also affect the ECS and contribute to the development of tolerance.
3. Individual characteristics of the user
The user’s genetics, age, sex, and overall health may also influence the development of tolerance. For instance, some individuals may have a genetic predisposition to develop tolerance more quickly. At the same time, older adults or those with certain medical conditions may be more sensitive to the effects of cannabis.
4. Other environmental and lifestyle factors
Other factors such as stress, diet, exercise, and sleep can also affect the ECS and potentially influence the development of tolerance. For instance, chronic stress or lack of sleep may impair the body’s ability to regulate the ECS and increase the likelihood of tolerance development.
Mechanisms of Tolerance Development
Some of the possible mechanisms by which tolerance develops to cannabis and how it affects the ECS include the following;
One mechanism is receptor desensitization and downregulation, where repeated exposure to cannabinoids leads to decreased number and responsiveness of the CB1 receptors in the ECS. This means that the receptors become less sensitive to the endocannabinoids and cannabinoids that bind to them, resulting in reduced effects of cannabis and the need for higher doses to experience the desired outcomes.
Another mechanism is the development of metabolic tolerance, where the body becomes more efficient at metabolizing cannabinoids and eliminating them from the system. This can lead to a shorter duration of effects and the need for more frequent dosing to maintain the desired level of cannabis use.
In addition to these mechanisms, tolerance may also result from changes in the activity of enzymes that break down endocannabinoids and cannabinoids in the ECS. For example, chronic use of cannabis may lead to an increase in the action of the enzyme FAAH, which breaks down anandamide, a key endocannabinoid involved in pain perception and mood regulation. This may contribute to a decrease in the availability of anandamide in the ECS and reduce the effectiveness of cannabis in producing its desired effects.
Effects of Tolerance on the ECS
The effects of tolerance on the ECS can be significant, potentially leading to dysregulation and disruption of various physiological processes usually regulated by the system. Below are some of the effects of tolerance on the ECS:
1. Reduced therapeutic effects
Tolerance can reduce the therapeutic effects of cannabis since the body becomes less responsive to the cannabinoids that bind to the CB1 receptors in the ECS. This can lead to the need for higher doses of cannabis to achieve the same level of therapeutic effects, which can increase the risk of adverse side effects and long-term harm.
2. Dependence and withdrawal symptoms
Tolerance can also lead to dependence on cannabis, where the body becomes accustomed to the presence of the drug and needs it to function normally. Upon cessation of cannabis use, the body may experience withdrawal symptoms such as anxiety, irritability, insomnia, and physical discomfort.
3. Increased risk of adverse side effects
Tolerance can increase the risk of adverse side effects associated with cannabis use, such as cognitive impairment, impaired coordination and judgment, and cardiovascular and respiratory problems. This is because higher doses of cannabis are needed to achieve the same level of therapeutic effects, which can lead to a higher concentration of cannabinoids in the system and a greater likelihood of harm.
Managing Tolerance to Optimize Therapeutic Potential
While tolerance to cannabis can be challenging to manage, there are several strategies that users can employ to optimize the therapeutic potential of the drug. One approach is to use cannabis in moderation, taking breaks between use to allow the body to reset and avoid desensitization of the ECS receptors. Also, shuffling between different strains with varying THC and CBD ratios can help prevent tolerance development. This is because different strains interact with the ECS in unique ways, and various strains can provide a diverse range of therapeutic effects. Another approach is to adjust the dosage of cannabis to match your tolerance level. Lower doses of cannabis can still produce therapeutic effects without leading to the development of tolerance.
It is worth noting that tolerance to cannabis is not necessarily a negative phenomenon. It can be an adaptive response of the body to repeated exposure to the drug. For instance, tolerance to the psychoactive effects of THC can enable users to maintain their daily functioning without impairments. Moreover, tolerance to the therapeutic effects of cannabis may indicate the need for higher doses or different strains to achieve the desired outcomes. Despite the potential benefits of tolerance, it is essential to minimize the risks associated with long-term cannabis use. Moreover, long-term cannabis use has been associated with adverse effects on mental health, such as an increased risk of psychosis and depression. Thus, it is crucial to monitor cannabis use and seek professional help if necessary.
