I hope to be killed by a half-ton of marijuana as well.
But for me, I would prefer to smoke (vape /eat) it, slowly, and die after finishing it, which would have to take around 50 years (my natural lifespan).
But - damn! - that is 10 kilos a year, which means almost a kilo a month. As long as I am allowed to give most of it away to friends, I will be fine.
I could probably use 4-5 grams a month and be high for much of my awake existence.
