I think prohibition is a massive failure of a policy and bullshit moral war and that everything about drugs would be safer and better if they were easily available to whoever seeks them.
However, I know from experience when you're desperate and not well that you'll reach for anything and this can often have severe, predictable collateral consequences for those around someone with maladaptive drug use.
Also people are generally dumb as fuck with drugs and we've all been there. Like, the stakes can be much higher with them involved and life is already basicaly a meat-grinder so I worry about people's abillity to learn to use responsibly and persevere or operate functionally in often deeply problematic home and work environments when its infinitely complicated by various random substances that can become lighter fuel for massive self-destruction and harm to others
