that is not true.

1 is a medicine and heals the body.
the other is a toxic poison.

1 has killed 0 and that is cannabis.
the other has killed millions.

cannabis has been shown to help people overcome addiction of all sorts, has alcohol ever shown to do the same? quite the opposite...

There is no evidence to suggest that cannabis is "bad in big and long-term doses" FOR EVERYONE. This is good news for those who have been using cannabis heavily on a daily basis for years or decades 👍so no, cannabis certainly isn't worse by a variety of metrics.
