Oh right ha. Phew.
Well I haven't smoked it for years but it's available.
People try to sell you stuff all the time, usually taxi guys but a lot of them are either marked or stooges for the police so I wouldn't advise taking the risk.
There are bars I know where they sell openly over the counter and these are ignored by and large by police, whether they are ran by mafia or just pay police subs I don't know.
But I've seen police sitting in a car waiting to nick people on the way out so again, full of risk.
Unless they know someone trustworthy I'd tell them to swerve it personally. Just go cocktails and take a bar girl home to reignite their marriage instead.
