Good question. It is a moral dilemma. Most of us went out of our way to find cannabis and made that choice to take the risk bringing it into our worlds, for our reasons, whatever they be. Now there's almost no taboo surrounding it what is the best balance of exposure going forward.
It's hard to believe that more teenagers won't be growing more weed now the climate has changed, i don't know about smoking, I started growing at 14 though and I know way more of the people I knew at that age would have done if it were legal. And there is no real guidance on what to grow or why to grow it for a young person, because they wont understand if you tried to explain daytime vs nighttime smoke. So maybe there are a few bumps in the road and lessons to be learned. Cannabis has very different effects on different people and despite what we tell ourselves it is addictive, it does fire off dopamine and through neural plasticity create a greater desire for it this is just how the brain works no matter what it is that makes you happy be it sex, alcohol, fast cars, computer games. All habits are addictive. Is it ethical to allow potentially more of this? well alcohol is the most pointless of poisons and that's always been state approved and gambling is the worst of the worst for me.
Humans should be free asap (as soon as they can) and allowed to taste and try what they like and be respected to do what they want with their time on this planet, if society is so perverse that young people start to medicate themselves out of existence and escape all day then society needs to look at why that is and hopefully fix the underlying cause of that which is largely this sick faux democratic fascist so called "capitalist" system that we are all indebted to.
The amount of extra damage caused to children and young adults by keeping this herb illegal is unconscionable and this so called "legal" way still has to better no matter what happens i think.
But yeah i'm a bit mixed on it partly because it's one state granted privilege in an ironic sea of fascism and taxation and denied rights, but it will all work itself out in the end i'm sure. Hopefully people start learning herbalism again and then the next generation can give the finger to the big oil/pharma corps and government snakes in their pockets.. just my random jumbled thoughts
