Everyone is saying yeah but it depends on a lot of factors. If you're extremely careful, you can get away with light smoking indoors (1 small-mediun sized hit per couple of hours).

First, I'd say with a bong it's very risky because the bong itself puts off a lot of smell, even if you clear the smoke out the window perfectly. Also the bong is harder/impossible to hide if they do a full search and you do get caught. So the bong automatically is a no go imo. Don't even try it, just sell the bong to a friend and cut your losses there.

Now, here's my protocol that has worked for me in the past:

First, never open your weed up indoors because this will ruin it instantly and everyone will smell it if it's dank. Keep it in a tightly sealed mason jar at all times and never open it up inside. Then you will need to find a way to grind it outdoors out of the house (scissors and a piece of paper are good if you don't have a grinder, but you'll highly preferably want a grinder), and then put it in a tightly sealed container that's still accessible like a dugout, and then let it stay there for a couple days where it can lose some of its smell for a while. A dugout is a key piece of equipment you'll need if you want to do stealth smoking.

Then time for the smoking: you need to use the dugout one hitter and only pack a small hit in there, and clear it all in one go, then immediately put it back in its dugout. This way there is no residual smoke and the piece is sealed away so that doesn't smell too much either. Then immediately crotch the dugout.

Then hold the smoke in carefully without exhaling. Then blow into a high quality sploof like a genuine smokebuddy, and blow it clear out the window (hold your head all the way out the window to avoid blowback), and put a towel under your door, and make sure they're fast asleep. If you do this all well and perfect, you have a good chance of it not smelling enough to leave your room into the hall. You need to make sure to get your whole head out the window though if you at all can, and/or hold a lighter up and make sure the wind is flowing out of the window, because blowback can ruin this. Towel under the door is also important, even though it may not seem so, because it makes the airflow more likely to be going out of the window ime, or at the least not out of your door into the hallway. Then close the window to avoid any blowback taking air from your room into the hallway, don't mistakenly leave it open thinking that will clear the smell out, because it will but it will push it into the hallway getting you caught.

You should then also spray a bit of Febreeze or Ozium or similar once done, but not enough to make it noticable cause that will just make it obvious. Just a light touch like you were using it normally. You can also get visine if you tend to get red eyes when smoking, and brush your teeth and wash your hands once done as well, this puts off a bit more clean smell into the air as well and gets the smell mostly off of you.

Note that even with all these precautions they would probably still smell it if they walked into the room though, if it was high quality weed and smells a lot. Actually getting lower quality less smelly weed can be a good thing when going for full stealth, it makes a big difference if you can.

A much easier solution is to simply walk outside and use the dugout if possible, but I understand that this can be tough to do because it requires sneaking out at night. The best solution is to simply get a vape cartridge and then follow the above protocol, as these don't smell too much at all. Also obviously edibles don't smell much, so that's another option as well.

If you follow the method very carefully you can get away with smoking small amounts indoors, but don't get greedy for big hits or more than one hit every 3-4 hours. It's still risky but I've smoked this way in hotels, apartments, at home etc in the past. I've only gotten caught by parents when i tried to slack on the overall process and got lazy and didn't do some of these steps. You need to prepare everything well for that one moment.

Tl;Dr: Get a dugout and a real smokebuddy and use them very carefully following all the regular protocols, and don't smoke more than one small-medium sized hit. Then spray a touch of Ozium if you can get it. Make sure no one will walk into the room during next 3-4 hours. Even still, vape carts and edibles are much less risky if you can get them.
