Some people might need to go outside because their significant other tells them to (don't like the smell), maybe they have a child in the house, and probably a handful of other reasons.
If I see a kid trying to dodge his/her parents I tell them they should respect their parents wish and get their own place if they wanna get high where they live. That's what I ended up doing personally.
This site should be 18+ IMO but on the other hand it is harm reduction to help a person switch from smoking to vaping if you can not convince them to wait to use cannabis. It might even keep them from getting busted.
I often wish I had waited until I was at least in my early-mid 20's to start experimenting though, rather than at 15. The human brain takes a good while to develop. Young people reading this should take note. Using drugs when you are under 25 or so is a bad idea, particularly on a regular basis. Your thought patterns are still developing. I guess I am a hypocrite, did it myself. But I never did it at my parents house.
Anyways that's what I have to say for those reading who are under 25 or so. You are probably okay with 21+ but I would not use it on a daily or multi daily basis until 25+. If you are high all the time while you are developing neural pathways, those pathways will solidify to a degree, shaping how you experience things even when you are not high. Using drugs changed my life for the worse for sure. But you can always change.
Even if you don't care what your parents say you should care about yourself. It's the smart thing to do, you have your whole life to experiment. It will still be a new experience.
Oh, now my parents let me vape at their house. My mom tried and did not like.
