Hoo boy, time to lay some knowledge on ya.

It makes me less prone to runaway trains of thought, sub-panic attacks I guess you might call them. I can just chill and focus on what’s in front of me. It’s also great for relieving some chronic pain I have when ibuprofen doesn’t cut it; it’s maybe a step above naproxen, and I think the pain relief is part of the general stress reduction that I perceive as anxiety relief.

If I’m making capsules, it tends to last longer (4–5 hours, peak around 3 hours), so I may only take it once or twice a day as a general relief thing; if I mix it with a beverage (fruit smoothies in my case) and drink it, it comes on stronger but doesn’t last as long (3–4 hours, peak around 1–2 hours), which is better for PRN relief, but if I do that then I might end up taking it thrice or, uh, fource a day, which feels like too much, so I try to avoid that. It’s also good to take periodic breaks to avoid building tolerance.

Typically I take larger doses (6–10g) of “down” red varieties (Maeng Da, Thai, Borneo, Bali) for anxiety, pain, and sleep; smaller doses (3–5g) of “up” green/white varieties (Jong Kong, Thai) for stimulation, as a less anxiety-inducing alternative to caffeine. The difference between “strains” is noticeable but usually not that significant in my experience; dosage is typically more important. I recommend avoiding extracts—they can be more addictive as they can be 10–50× more potent than regular leaf powder (1–2% mitragynine/7-OH-mitragynine), and I find them less pleasant anyway.

It doesn’t cause any cognitive impairment that I’ve observed. For some reason it especially makes me want to write, which is great for documenting my code and figuring out a problem, but it doesn’t provide any real cognitive boost either. Taking a low dose before class might make you more energetic and social, but overall I don’t think it’d help or harm your focus much. Personally, when taking an “up” dose, I’d rather clean or go for a walk than go to class/work. Different people react differently, of course.

If you take too much, it’ll make you woozy, sleepy, and nauseated, which as you can imagine isn’t great for getting things done. If that happens, you pretty much need to drink water, eat food, lie down, close your eyes, wait for it to pass—or barf if you need to. Most people only take too much kratom once, hah—it’s highly unpleasant.

Kratom is not a wonder-drug—all it really does in my experience is take you from “not fine” to just “fine”. If you’re just looking to get “high”, kratom is not for you. It is habit-forming and can be addictive with frequent high doses or especially when taking extracts. Side effects may include constipation, more frequent urination, irritability, and (rarely) reduced testosterone in males. Withdrawal symptoms may include sweating, runny nose, diarrhea, dilated pupils, and elevated testosterone. Most people don’t experience most of these side effects or withdrawal symptoms, though.

Finally, and most importantly, kratom is under-researched and caveat emptor. There have been no confirmed cases of kratom alone causing death, but as a precaution it should not be taken in conjunction with other drugs or medications, and should only be purchased from reputable sellers; if you’re buying it in a smoke shop, make sure it’s a known, reputable brand in properly sealed packaging. My hope is that it will remain legal and be regulated for quality and purity in the future.
