Sigs Not Allowed To Smoke??

I recently got a sigs bid from this tall lanky wonk faced goober and we were just chilling when I asked if they like to smoke in the house at all. The guy kinda just avoided the question though and I was pretty confused. That was until my buddy in bromley with an older brother in the house said they're not even allowed to burn it's like against their by laws. For a guy that burns and mooks hella this is kinda a deal breaker for me. Can anyone confirm??
