There are plenty of threads like this, but a little tip is to make a doob tube. Just make one and you can smoke in your house if you use a bong/pipe/etc.....or use a vape. Vapes even conserve weed. Hell you could even do a vape/doob toob combo. Also smoking in the shower is a good place. Maybe use a doob toob in there too. But yeah, pretty easy not to get caught as long as you aren't clumsy, careless, or have REALLY nosey parents.
