> and I finish the joint I was smoking last night before bed, which is sitting on my bedside table. How should such a person set up their smoke detectors? I'm thinking: False alarms triggered by the marijuana smoke might disrupt their calm, and removing batteries and being in a perpetual cloudy-headed state could lead to batteries not getting back in. And if they're smoking from bed, they'll probably need more protection than most people, for detecting smoldering bed sheets.

Cigarette-type smoke doesn’t trigger smoke alarms.

  It really depends on the kind of smoke alarm. I'm sure most home style smoke alarms aren't set off by that, since they're usually an ionization style detector. Photoelectric detectors can be far more sensitive though. Moreso, I imagine the detection has less to do with the type of smoke, and the density of it. Directly exhaling into a smoke alarm can set off the detector, when the smoke is at its most dense.

I worried about that once too. It actually takes a lot of smoke to set those bad boys off. Less than a gram of burned leaf isn’t going to do it.

What a condescending comment. There is always such snarky comments on HN whenever smoking Cannabis is mentioned. I was under the impression that the average HN reader had above average intelligence and open mindedness, but posts like this remind me often that isnt true. EDIT: I have apologised for the tone of this post below, and come to a very amicable conclusion with OP.

  Can you help me by saying how it is condescending, so I can try to avoid that mistake in the future?

    For the record I didn’t consider your post condescending

    Don’t worry about it dude, your comment wasn’t condescending at all and is actually a good word of caution for those who like to smoke indoors!

    Certainly: > False alarms triggered by the marijuana smoke might disrupt their calm >removing batteries and being in a perpetual cloudy-headed state could lead to batteries not getting back in. > if they're smoking from bed, they'll probably need more protection than most people, for detecting smoldering bed sheets These are all very condescending points. They assume that a Cannabis smoker requires a certain level of calm and cant handle anything more, that they are unable to do something as simple as changing batteries, and that they are likely to burn themselves alive in bed. I am assuming you are insinuating that cannabis makes people 'stupid', and if I am wrong this is what your point comes across as. Perhaps next time you might not immediately make such negative statements against a large group of people, even in a sarcastic or jokey way. This is also assuming your last post was serious and you are genuinely interested in how you are putting people down unnecessarily.

      Sorry for the offense. I can see how it might be interpreted that way. It wasn't my intent to joke, but actually to care. The article talked about willingly being calm, and caring less, and I honestly don't know whether that would extend to being more prone to the (not-uncommon) practice of removing batteries from an alarm, and then neglecting to put them back in. I've also frequently heard of falling asleep while smoking as being a cause of house fires. FWIW, some of my work has involved safety. And some of my other work has involved human factors engineering, and more generally looking at how people behave in reality, and designing from there. No disrespect intended to people. If you read my comment in that light, does it seem less offensive than before? I'll be more sensitive. Including being aware that I'm not familiar with marijuana, and bound to make incorrect guesses/assumptions, which I now realize could be frustrating to people. And also now being aware that some people might be accustomed to snarky comments around the topic of marijuana, and be on guard against that.

Smoke alarms don’t react with marijuana/cigarette smoke unless you deliberately blow the smoke into it. I don’t know why but I’ve smoked in my room countless times and it never went off. It’s not a faulty detector either because it has went off before!

I've blown directly into the detector accidentally, and it's sat there quietly. It takes a lot, and I assume that's intentional. Smoldering sheets and drywall are going to produce a lot more smoke than a joint.

My mom told me she quit smoking in her 20's because of the health risk. Oh, I said, like cancer, heart disease or hypertension? No, she was in her 20's. None of that mattered. However a friend of her's set fire to the bed she was sleeping in. That made a very big impression on my Mom. She apparently liked a cigarette before bed and had no faith in her ability to just stop smoking then - so she quite entirely. For some reason it makes me laugh.
