> This was not your average weed. The oil and waxes she bought from dealers were typically about 90 percent THC, the psychoactive component in marijuana.
referred to later as "THC concentrates".
BTW, the authorities have been saying for decades that level of THC in weed is much higher than it used to be, I believe as a way to convince older adults that their personal experience with cannabis is not trustworthy.
For example, "Many people who have voted for legalization thought they were talking about the marijuana of the 1960s to 1980s when the THC content was less than 2%." from https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6312155/ .
But as https://www.theatlantic.com/technology/archive/2015/03/was-m... points out, "incomplete government data encourages a pervasive pot myth." ... "it's difficult if not impossible to classify average potency in a way that can be tracked meaningfully over time. So while there's almost certainly more super-strong pot available today—if only by the fact that it's now legal to buy in multiple states—it doesn't mean that all marijuana is ultra-potent today, which is how the narrative about potency is often framed."

Likely because of the illegality of carrying out those tests.
> A recent study found that people who used marijuana had a greater likelihood of suicidal ideation, plan and attempt than those who did not use the drug at all.
As the underlying paper at https://jamanetwork.com/journals/jamanetworkopen/fullarticle... points out, "Future research is needed to examine the increase in suicidality and to determine whether it is cannabis use or overlapping risk factors that increase risks for both.".
Eg, people experiencing suicidal ideation could be self-medicating with marijuana, and w/o that option would self-medicate with alcohol and have a higher risk of suicide.
