High levels of THC cause psychosis. That has been scientifically proven and known for a long time.

You cited a case study. Cool beans.
Please, I can cite source after source after source. Anyone who has ever gotten too high understands this connection. Edibles are substantially stronger than smoking and are now more available than ever. This doesn't surprise me in the least and it will happen again.
Post something that actually has external validity.
What I posted is indeed valid. Controlled studies are extremely accurate. This is not new and I am baffled that you didn't already know this.
Background
People who use cannabis have an increased risk of psychosis, an effect attributed to the active ingredient Δ9-tetrahydrocannabinol (Δ9-THC). There has recently been concern over an increase in the concentration of Δ9-THC in the cannabis available in many countries.
Aims
To investigate whether people with a first episode of psychosis were particularly likely to use high-potency cannabis.
Method
We collected information on cannabis use from 280 cases presenting with a first episode of psychosis to the South London & Maudsley National Health Service (NHS) Foundation Trust, and from 174 healthy controls recruited from the local population.
Results
There was no significant difference between cases and controls in whether they had ever taken cannabis, or age at first use. However, those in the cases group were more likely to be current daily users (OR = 6.4) and to have smoked cannabis for more than 5 years (OR = 2.1). Among those who used cannabis, 78% of the cases group used high-potency cannabis (sinsemilla, ‘ skunk’) compared with 37% of the control group (OR 6.8).
Conclusions
The finding that people with a first episode of psychosis had smoked higher-potency cannabis, for longer and with greater frequency, than a healthy control group is consistent with the hypothesis that Δ9-THC is the active ingredient increasing risk of psychosis. This has important public health implications, given the increased availability and use of high-potency cannabis.

Let me ask you a question? Do you have much experience with THC?
