I am in favour of legalisation across the board, recreational, medicinal, whatever, but at the very least, medicinal. Too many people have listened to reefer madness nonsense over the years and have had their critical faculties blunted by this hysterical abolitionist propaganda pushed by the US alcohol lobby. Innumerable people have suffered because of this emotion-based idiocy.
No, cannabis is not harmless. Any substance has the potential to cause harm when abused. But the harm caused by criminalisation is many times worse.
I think this has been covered in earlier threads. Personally I don't use the stuff, never have and I doubt I ever will. But I will be voting Yes for pretty much these reasons.
The other reason is my offspring. I hope they never use it when they are old enough for it to be possible, and I will certainly tell them firmly that they shouldn't. But if they do, I would rather they get actual weed from a licensed and regulated seller. Not from their local gang house where they will be offered who knows what from someones backyard chemistry set and told it's weed, as well as some meth or firearms they want them. And possibly robbed and beaten up in the process.
Legalisation will be pretty much neutral for users, as weed is fairly readily and affordably available for anyone who wants it. But it will be a calamity for the gangs (who will lose a lot of their income), and also enable justice resources to be focused on things that matter far more. Thus, I'm in favour.
