True to an extent, but looking at it from an individual's perspective, it can be devastating. I've seen people stop to function as human beings because of this.
What I am genuinely concerned about is the scale. So far, we don't have too much insights into the long term effects of this, both on individual and on society level. Cannabis addiction can cause long term psychological issues, and it will be years before we will truly understand what this means for us.
I've seen people so addicted to it that they stopped going to work and completely ignored their family. I don't have numbers to put it into perspective, but the sheer level of addiction was beyond what I thought was realistic.
you detach it from other drugs (the regular dealer will also have other stuff for sale - not an issue if you buy officially or grow yourself).
Con:
despite what people claim, there are people that get highly addicted to cannabis. Probably similar to alcohol, you'd say? Well, in my unpopular opinion, alcohol also shouldn't be available the way it currently is (make it insanely expensive please).
most people consume it with tobacco, so there's that to deal with.
Screw whatever other people might think. It simply doesn't matter. You're happy, your wife is happy, your child will be happy. That's all that matters.
For us, it is the exact opposite - we decided we didn't want to have children. People keep asking why not, and try to convince us that children are sort of a must have in our age. But you know what? Screw them - our lifes, our decision.
Seek medical help. If drugs of any kind are a good option, a trusted medical advisor / doctor will support you on the way.
