I'm thinking about substance use in general that it might even have some benefits but with each repetition the problem use threshold is getting closer. And we have no way of knowing where the threshold is for each of us. It might be ten reps or ten thousand, but even considering the genetics, trauma, etc we cannot know whether the next rep is going to be over the threshold. In addition the threshold in most cases becomes visible after a long time it's been crossed.
