How? For an adult human, marijuana is one of the safest substances out there. Easily safer than alcohol. Don't drive or operate heavy machinery and you'll be fine.
What percentage of people end up in the hospital from it, and how?
I'm not sure I'd recommend edibles for a first-timer. The high lasts a fairly long time, so if you don't like the feeling it's kind of annoying. Having a friend is always a good idea though.
That said, there’s really few cases of cannabis use going poorly, especially in the context of other drugs (alcohol, tobacco) and their documented harm. I’m not a doctor, I’m not a lawyer, etc so do your own research, but it is most likely a safe activity at a “normal” dosage for the average person.
> If you really want to do it, try low grade edibles; do it in the presence of a friend so they can get you medical help if you need it. Only a small number of people will have a problem, but don’t take stupid chances with your body and mind, people.
I do agree with this. Edibles are good because you don’t have to smoke, but bad because the affects can take upwards of 2Hr to hit. it can be hard to dose and many people get impatient and take more and then they don’t enjoy the sensation. There’s almost no documented case of overdosing especially in the context of amounts someone might buy, so that’s not likely a concern, but just having a bad time is likely. Do it with friends - it’s also more fun that way. Most people don’t turn 21 and start drinking alone, so don’t do this alone either. Establishing a sober medical monitor type relationship for taking a small edible is a bit extreme but don’t be alone.
