Dude don't smoke inside it just isn't worth it if you would get in trouble if somebody smelled it. It is ok to smoke in your garage because one time i blaze a bowl in my garage when it was shut, went inside and opened the garage door and 5 minutes later i hear my front door open and my mom is home and she didnt smell anything. But ya garage is fine just open the garage door for like 15 minutes and you will fine but I mostly enjoy sitting on my back deck while smoking so maybe try that too.
