What's your poison for the night?

This caught my eye as my 19-year-old son recently died between 6:45 and 7:25 PM on Friday, March 20th, 2020 in Merced California. A wax vape pen was found by him about 8:15 PM. Wax is a concentrated thc product and obtained from mj leaves by extraction. He also used a nicotine vape, adderol (on 3 8), alcohol, and percocet (of which he was dying from over-dosing on 12 15 2019 before being saved) and elsavil (for migraines) recently. In addition he used coke, xanax, molly (ecstasy), and lean ( a purple liquid based upon codeine) in highschool. Am curious if other folks have run accross stories of people undering going heart attacks and cardiac arrest and dying suddenly on the spot in the very act of using the thc
and/or nicotine in vaping products.
