A single dose is probably irrelevant for health. But I’d argue that (mental) health would suffer way more than compared to all health effects of sugar.
I’m not against legalizing cannabis, but the cannabis community downplays the risks of regular consumption a lot.
Have you seen the mental health statistics? What they all have in common in having been raised, and living on, refined sugar (and other foods unsuitable for human consumption), not cannabis.
I'm not saying cannabis is a always a good idea, but even so mainly because it's often in the context of having already frail health, and combination, oftentimes with literal poisons like alcohol.
There's a huge hypocrisy around it being a question of public health; it's not, if it were, sugar would be highly taxed and regulated (esp. not being marketed to children), alcohol would be banned, etc. It still surprises me this hasn't permeated yet, as the information is now widely available.
How do you know the cause of your acquaintance's suicide?

Of course, if we're instead making an argument about liberty, matters are different.
We've already decided alcohol is fine from a liberty perspective, so if the argument against cannabis is from a harm perspective, and cannabis is less harmful than alcohol, then cannabis should be fine too.
"dry laws" have also mostly resulted in proliferation of illegal alcohol sales and criminal groups dealing with that.
perhaps harm reduction should be dealt with in a different way than prohibition and use of force.
I'm for tolerating both alcohol and cannabis, but without mass marketing (ads, ...).
One struggle we face is the large inflow of other drugs, the resulting damage (for example from crack) currently from south America, the import of crime from there and the use of the drug business of legal cannabis business to expand their other drug business.
And youngsters who smoke weed in the streets learn to hate cops. Which may or may not be a bad thing.
