No I'm not taking it and never have!! I've discovered that someone very close to me is growing it in their garage behind a secret wall, and then harvesting it and selling it. It's meant to be a one off thing but I'm really shocked. I had no idea as I have no sense of smell. I've told them( it's the man doing it but woman knows) how stupid they are being, and the woman isn't happy about it at but he says he's just doing it to get some money for the family. Apart from being worried sick for them it suddenly occurred to me - what on earth would happen if the police turned up whilst I was there?? Would I be arrested??
Send them an anonymous letter purporting to be one of the neighbors saying the constant smell of cannabis coming from their property is making them ill and if something isn't done about it pronto you will inform the police.
"Hopefully yes, just for leaving them to get on with it."
As the above poster said you are now a conspirator as you know about it and haven't informed the law so take my advice or you will have to make a phone call to the police.
I'm guessing the police and not your neighbors op? If so why not phone them now? For all you know the police might have a raid lined up for their properties at 4am. Unlikely but possible and you then don't want to tell the police that you "was" going to ring them but left it. You have to look after number 1 which is you.
