“Contributing to the problem: The amount of THC in today’s marijuana has skyrocketed from approximately 4% in the 1970s to an average of 18% to 20% today, D’Souza said.

“You can now buy cannabis in dispensaries that has a THC content of 35%,” he said. “Marijuana concentrates, which are similar to nicotine concentrates, have a THC content of 80%. That’s about 20 times greater than the THC content of cannabis from the 1960s and ‘70s.”

Cannabis use is common among those with mental health conditions, and many people report using cannabis to manage mental health symptoms.

It is important for clinicians to understand the lack of clear benefits of cannabis for mental health conditions and the potential for substantial adverse effects.

📌 This Review summarizes the current evidence on the effects of cannabis on commonly encountered mental health conditions and provides clinicians with basic information about cannabis pharmacology and biology.

The CHS and pesticide theory will likely never die, BUT our recent research may help give some clarity.

Since testing products wasn't part of the study for multiple reasons, we compared the symptoms people experienced in both the prodrome and hyperemetic phases to see if symptoms were different, depending on the source of the cannabis.

Yes we even asked about scromiting.

Guess what? Symptoms did not differ between the source of the weed. Across the US and 5 continents.

As we said in the paper: "Symptom consistency across these varied sourcing categories (Fig. 6) suggests that a single contaminant or pesticide is unlikely to be the cause. Most pesticides have distinct toxicological profiles, and it is improbable that all market segments
would converge on a common exposure capable of producing an identical syndrome."

For those adamant about a contaminant, the question is what contaminant is present across the board in cannabis that would cause this specific set of symptoms in only a subset of its consumers?
