I tested whether cannabis really can boost the runner’s high

In the world of fitness and wellness, cannabis has long been touted as a tool to enhance performance and elevate the experience of activities like running and yoga. Proponents claim that the psychoactive effects of cannabis, particularly those related to the THC compound, can heighten senses, reduce pain, and even boost endorphin production. Intrigued by these claims, I decided to delve into the research and test the waters—literally—by experimenting with cannabis during my own runs.

The scientific literature on cannabis and exercise is mixed, but some studies suggest that it can indeed have positive effects. For instance, a 2019 review published in the Journal of Sports Sciences found that cannabis use might improve mood and reduce anxiety during physical activity. Additionally, research has shown that cannabis can alleviate muscle pain and inflammation, which could be beneficial for athletes recovering from intense workouts. However, other studies have raised concerns about the potential for impaired coordination and judgment under the influence of cannabis, which could pose risks during high-intensity activities.

With this background in mind, I decided to conduct a personal experiment. I chose to run a 5-kilometer trail run, a distance I was comfortable with, and split it into two parts: one where I would consume cannabis beforehand, and another where I would not. For the cannabis-assisted run, I opted for a vaporizer to ensure I was ingesting the substance in its purest form, avoiding the potential liver damage associated with smoking. I calculated the dosage based on my body weight and experience with cannabis, aiming for a moderate effect.

As I waited for the cannabis to take effect, I felt a sense of relaxation wash over me. My mind felt clearer, and I noticed a heightened awareness of my surroundings—the rustling of leaves, the scent of pine in the air, and the sound of my own breath. When I began running, I felt a sense of euphoria that was both familiar and new. My stride seemed more fluid, and I felt as though I was gliding over the trail rather than striding. I noticed that I was paying closer attention to my body, monitoring my form and breathing patterns more intently than usual.

Despite the initial positive experience, I also noticed some potential drawbacks. My focus seemed to fluctuate, and at times, I found myself momentarily losing track of my surroundings. I also felt a slight increase in heart rate, which could have been due to the combination of cannabis and exercise. Nonetheless, I completed the run without incident, and the sense of accomplishment was undeniably heightened.

For the control run, I followed the same route and distance but did not consume cannabis. While the experience was enjoyable, it lacked the heightened awareness I had experienced earlier. My mind felt more focused on the task at hand, and I was less attuned to my environment. The sense of euphoria was still present, but it felt more subdued.

Upon reflecting on my personal experiment, I realized that the effects of cannabis on exercise are highly individual and depend on factors such as dosage, tolerance, and personal preferences. For some runners and yogis, the psychoactive effects of cannabis may indeed enhance their routines, providing a unique "runner's high" that transcends the ordinary. However, it is crucial to approach such experiments with caution, as the potential risks—such as impaired judgment and coordination—must be weighed against the potential benefits.

In conclusion, while the scientific evidence on cannabis and exercise is still emerging, my personal experience suggests that it can indeed have a profound impact on the sensory and emotional aspects of physical activity. For those who choose to explore this avenue, it is essential to do so responsibly, considering both the potential advantages and the inherent risks. Ultimately, the decision to incorporate cannabis into one's fitness routine should be based on a thorough understanding of individual tolerance, the specific goals of the activity, and the potential consequences of its use.

A simple way to get more value from metrics
A simple way to get more value from metrics
We spent one day 1 building a system that immediately found a mid 7 figure optimization (which ended up shipping). In the first year, we shipped mid 8 figures per year worth of cost savings as a result. The key feature this system introduces is the ability to query metrics data across all hosts and all services and over any period of time (since inception), so we've called it LongTermMetrics (LTM) internally since I like boring, descriptive, names. This got started when I was looking for a starter project that would both help me understand the Twitter infra stack and also have some easily quantifiable value. Andy Wilcox suggested looking at JVM survivor space utilization for some large services. If you're not familiar with what survivor space is, you can think of it as a configurable, fixed-size buffer, in the JVM (at least if you use the GC algorithm that's default at Twitter). At the time, if you looked at a random large services, you'd usually find that either: The buffer was too small, resulting in poor performance, sometimes catastrophically poor when under high load. The buffer was too large, resulting in wasted memory, i.e., wasted money. But instead of looking at random services, there's no fundamental reason that we shouldn't be able to query all services and get a list of which services have room for improvement in their configuration, sorted by performance degradation or cost savings. And if we write that query for JVM survivor space, this also
