Actually there are some case reports where people have died from cardiac arrest following large amounts of concentrate. I was trying to find the paper I read with two specific cases one patient consumed 2.1g I think they were like 38. There are noe plenty of other reports in the literature connecting cannabis, specifically THC to cardiac issuesI suppose you are correct but I don’t class it as one of the harmful ones. You can od on any drug if too much has been consumed. Though as far as I know no human being has successfully managed to consume enough cannabis to do this. Yet
Alcohol and nicotine are actually surprisingly easy to overdose with and these i class as way harder than weed
