I know people in the kinds of circles where micro-dosing is popular, in San Francisco. I can say with absolute certainty, walks in the park are still more popular.

Although, if the homeless problem gets any worse, who knows.

Yes, it's a pretty narrow group where microdosing is even on really on the radar, let alone a common occurrence. It makes good copy though, so the amount of media attention it has had is way out of proportion to it's actual impact.

I know 0 people who have mentioned microdosing, or even know what that is. Hacker News has a way of distorting reality, citing specific studies, reinforcing and arguing against them with anecdata. Creating a bubble within the Hacker News reality. Many of the studies that these people reference, in psychology, and in health, the only way to get information out of them is through meta-analysis of many studies. These fields are so contradictory within themselves, it's not even worth looking at most "individual" studies. Sometimes even the meta-analysis can be wrong as well.

the homeless aren't an impediment to walking around unless you live in the tenderloin or someplace downtown that has an especially big problem. In most of the city they are around, but not bothering anybody. Also much of the "walking in nature" that people do is hiking outside the city where the homeless problem can't have an effect.

Errr, I live in San Francisco. We do almost everything in parks. The massive Golden Gate Park is brimming with people every weekend.

Funny you mention it, you can buy mushrooms, LSD, DMT, whatever on hippie hill in Golden Gate Park at all hours of the day. Although you're right, most people there are just walking around oblivious to all the hippies tripping.

As an aside, microdosing is a placebo for people too scared to take a real trip.

Well it's not a placebo in a strict sense.

I lived in Berkeley, there was no circle in which microdosing is more popular than going to a park. Sure, people know of microdosing, but nowhere even close to a majority do it regularly.
