"They do give it away" - my point wasn't that this doesn't happen under the present regime, but that this is very tied up with the fact of illegality.

Drug dealers do not give out currently give out free alcopops, or even tubes of Evostik, so why should we anticipate them to be any more likely to give out free joints, once the normal source of supply for cannabis is somewhere else?

Somehow there always seems to be a tendency to read into a post what we expect to find there, when what is actually there can be significantly different. And then we leap to some conclusion that can be poles removed from the truth, like Strollin'Johnny. "What a sheltered Airy-Fairy Cloud Cuckoo Land you must live in" - if only!
