“I Know My Limits” Is Not a Safety Plan
A San Francisco study on risk perception shows why accurate information beats both scare tactics and false confidence.

Many people partake in "risky" behavior with or without mind-altering substances, but things get much cloudier when attraction, sleep deprivation, loneliness, and a very large, hard cock enter the room. I’ve heard some messed-up stories about someone being taken past their limits, or worse, only to backtrack the blame to themselves for being under the influence or not knowing any better. Consent does not stop when you take that mind-altering substance, and unfortunately people are still blaming themselves for not speaking up when they aren't able to.
A 2025 study examined substance-use harm perceptions among help-seeking men who have sex with men and transgender women in San Francisco. Nearly all participants saw sharing needles and nonprescription opioid use as high risk. However, a significant minority—including people experiencing unstable housing or living below the federal poverty line—were far more likely to view needle sharing, opioid use, and sex while under the influence as low risk.
Harm perception matters because people don’t make decisions based solely on medical facts. We use past experiences to make decisions about future ones. Someone might think, “I’ve done this twenty times, and nothing bad happened,” which feels reassuring but doesn’t guarantee that the twenty-first time will be safe.
No matter what we are doing with our bodies, it should never be "Uncool" to assess and reassess the benefits and risks while you're having fun. Everything from condomless sex, mind-altering substances, or more advanced kink that involves impact, restraint, or other scenes that could result in harm, like sounding, comes with an amount of risk. Making a game plan on what to do when the cards aren't right isn't being a party pooper; it's saving someone's life, including your own.
I think people deserve accurate information without scare tactics. Exaggerating risk destroys trust, minimizing it can get someone hurt, and lacking insight when under the influence could get someone killed. Every risk we take is on a sliding scale (no risk to very risky), and that scale looks pretty lopsided when you load on meth, GHB, and a hard dick.
A real safety plan can include telling a trusted person where you are, carrying naloxone, avoiding using alone, checking medication interactions, setting consent boundaries before getting high, and keeping antiretroviral or PrEP doses accessible. This last one is the most important in my opinion: knowing when symptoms require emergency care.
You don’t have to become the helicopter mom of the sex party to take care of yourself and others. You just need a backup plan for the nights when everything doesn’t go according to plan.

**Research Note**
I found it quite odd that, with the majority of IV substance use among MSM and transgender women being methamphetamine, it wasn’t part of the survey questions. While opioids are still the number one killer, they aren’t the most common IV drug that people are using in our community.

The Study Didn't Even Ask About Meth
Last week I wrote about a San Francisco study that looked at how MSM and trans women perceive risk from substance use. It covered needle sharing, opioids, sex while under the influence. Solid research. But the researchers themselves flagged something I haven't been able to stop thinking about.
