As long as they are under control and not doing a bunch of stupid shit then yes, I do not mind it. Being a 15 year old being raised in Australia. I can point out many, many different people who smoke marijuana. Hell, even my teachers smoke marijuana. HELL, even police officers suspend marijuana off of people to smoke it themselves!! If it actually helps someone with their struggle, e.g: Depression, Cancer, etc, then I personally think that it is fine!
