It’s not addictive...Okay, then let's look at this using the above perspective of "simply selling a product without any regard for social consequences". There are a bunch of guys on here "selling" the virtues of weed due to the simple fact they want to use it, and legalising it would make that easier. People like the person in question, with pre-existing mental issues, buys what people are pushing that it's a fantastic substance that is great for a whole assortment of reasons, particular pain / mental demons. Sounds like a great thing to use, especially by someone who appears to be struggling. Bam, there you go. Not only negative reactions to it, but addiction and the associated problem inherent, like the damage to relationships and general life. There are legit far reaching consequences.
Is it as bad as getting off your tits and trying to take on 5 cops and ending up in jail? No. But it's certainly not something you'd wish on someone, and hence the reason I do not buy in to this "it's safe" agenda that people want to push.
I do understand your point, though.
