It frustrates me that the tech scene seems to accept such behaviours as smoking weed quite easily. Note the numerous replies to your comment clamouring to it's defence!
I've not known a single long-term user of cannabis to be a happy, healthy adult. Quite the opposite. I think the dangers of cannabis are quite understated and the current trend toward mass-legislation concerns me. It should be noted that I live in England, where we are renown for having stronger strains... This perhaps affects my outlook.
