While it's still full steam ahead to stamp down hard on the more popular type of smoke, the other kind - that is, marijuana consumption - has never enjoyed more of a groundswell of support for its decriminalisation and/or legalisation.
In the vanguard of the movement are those who argue that it is hugely beneficial for its pain relief properties. In hideous tobacco-hating California, for example, medical marijuana has been legal for quite a while, and recent moves have attempted to bring recreational use into the same category.
So a 'highless' marijuana crop developed by a team in Israel may come as a bit of a blow to the ageing lefty hippy generation of San Fran and environs who are campaigning so vociferously to enjoy their favoured magic smoke.
In this brave new health obsessed and medicalised world, drugs are to treat illness only, and only to be made by the pharmaceutical industry. Never must they also be enjoyed. D'you see?
Whilst I agree with their cause, perhaps the health angle isn't the best way for the pro-drugs lobby to approach cannabis legalisation anymore, now science has found a way of taking the fun out of it.
I can hear the sniggers from some of you from here. Keep it down, eh?
