A bit of endocannabinoids do you good ... possibly

Maybe what I need to help my brain is to 'awaken your endocannabinoid senses.'

I was a little surprised to see that on a poster in an e-cigarette shop window. Should we be awakening those senses I asked Helen, who's a nurse and knows about such things.

'Those are the good bits of cannabis,' Helen explained. 'The pain killing bits. But I don't think they're actually legal here.'

So I was probably right in the first place. People already think I'm a drinker.
