Cannabis is neither physically addictive nor toxic in any demonstrated way, it is beneficial to health for people who have conditions that it treats, and no possibility of overdose fatality exists. It is, in short, perhaps the safest medicine known to humankind.
Those who, like myself, suffer from chronic pain, and use cannabis under a doctor’s recommendation, will use it every single day, because we benefit from having pain relief, and it does not impair our function. To the contrary, we are less functional without it because we then have untreated pain.
You cannot honestly say that it would be better to take some prescribed opiate or over-the-counter drug that causes liver damage. Cannabis does not cause organ damage.
Those who have no pain to begin with will have no need of cannabis, but those who are addicted to other drugs would be well advised to switch, were it only legal to do so. Cannabis can treat cocaine, heroin and other dependency, by helping make withdrawal less difficult. Those other drugs can kill, and have very serious withdrawal symptoms that can be dangerous, making their addictiveness truly horrific.
Cannabis is benign, it is beneficial, it is good. It is not for everyone, some will dislike it (and I dislike broccoli, so there). I would not give it to children unless a doctor thought it was appropriate to recommend. There is no real harm in adults using cannabis, except for the harms consequent to prohibition. These are points you may wish to contest, and the social consequences of cannabis are important considerations as well. I’m looking forward to having that conversation with more of you.
