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

In the world of fitness and wellness, cannabis has become increasingly popular as a supplement for enhancing performance and elevating mood. Runners, yogis, and other athletes often cite the benefits of using cannabis to improve their routines, claiming it helps with pain relief, reduces anxiety, and boosts the "runner's high." Intrigued by these claims, I decided to delve into the research and test it out for myself.

The scientific community has shown mixed results regarding the effects of cannabis on physical performance. Some studies suggest that cannabis can enhance endurance and reduce muscle soreness, while others argue that it may impair cognitive functions and slow reaction times. To understand the impact of cannabis on my own running experience, I began by reviewing the available research.

One key study published in the Journal of Sports Sciences found that cannabis users reported increased pain tolerance and improved mood during exercise. However, another study in the International Journal of Sports Physiology and Performance indicated that cannabis consumption could negatively affect cardiovascular performance and increase the risk of injury. These conflicting findings left me eager to test the effects firsthand.

I decided to conduct a personal experiment over a period of several weeks. I chose to run a consistent 5-kilometer route three times a week, both with and without cannabis consumption. On days when I used cannabis, I ensured to abide by recommended dosages and allowed sufficient time for the effects to wear off before running.

On the first day of my experiment, I consumed a small dose of cannabis an hour before my run. As I began my 5-kilometer route, I noticed an immediate sense of relaxation and reduced anxiety. My breathing felt more relaxed, and I felt a sense of euphoria that I hadn't experienced in a while. However, I also noticed that my focus seemed slightly impaired, and I struggled to maintain my usual pace.

Over the next few weeks, I continued to alternate between running with and without cannabis. On days when I used cannabis, I often felt a heightened sense of enjoyment during my runs, but I also experienced occasional dizziness and a reduced ability to concentrate. In contrast, on days when I didn't use cannabis, I maintained my usual level of focus and endurance.

Interestingly, I also noticed a difference in my post-run recovery. After runs with cannabis, I felt a sense of deep relaxation and a reduced need for stretching. However, I also experienced more severe muscle soreness the following day. Without cannabis, my recovery felt more balanced, with manageable soreness and a sense of rejuvenation.

As I analyzed my results, I realized that the effects of cannabis on my running experience were indeed mixed. While it provided a sense of relaxation and enjoyment, it also seemed to impair my cognitive performance and prolong recovery time. This personal experiment aligned with some of the research suggesting that cannabis may not be a universally beneficial tool for athletes.

However, it's important to note that individual experiences with cannabis can vary greatly. Some users may find that it enhances their performance and well-being, while others, like myself, may experience more drawbacks. It's crucial for individuals to consider their personal tolerance levels, the specific strains they consume, and the potential risks before incorporating cannabis into their fitness routines.

In conclusion, while cannabis has the potential to offer certain benefits for fitness enthusiasts, such as reduced anxiety and increased pain tolerance, it may also come with trade-offs like impaired cognitive function and prolonged recovery. As more research is conducted in this area, it will be essential for athletes and wellness seekers to make informed decisions about the role of cannabis in their lives. For now, I will continue to explore other methods for enhancing my running experience, but I remain intrigued by the diverse ways in which cannabis can impact human behavior and performance.

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
