Please answer my question, please

So I'm actually underage and I know it will put some of you off from answering (I'm 17) but I gotta say that I'll do it anyways so not answering wouldn't really change anything lol.

So my question is - what drug is best to do at house without parents noticing. I'm looking for something that is easy to act normal on or something that lasts for short amount of time. I can't smoke weed inside and my eyes also get very red when I smoke. I live only with my mom and I have separate room for myself. The thing is she never leaves the house since she works from home and I am almost never alone. She told me she will leave tommorow and now she said she won't, I wanted to chill out and smoke some weed but I cant now and I really need an answer since I really want to do something so please answer.
