What happened

In recent years, we’ve seen a sizeable shift in medicinal cannabis prescribing, to products containing higher levels of THC (tetrahydrocannabinol) – the component that can cause drowsiness or a high.

Why it matters

Now, our new study shows some of the harms with this shift, including from products containing far more THC than naturally found in cannabis plants.

Common ground

We found more than half of all cases of adverse events involving unapproved medicinal cannabis products reported to the Therapeutic Goods Administration (TGA) were related to products containing higher strengths of THC.

Perspective signals

The tension in the story is sharpened by Loaded Language, Appeal to Fear: language that can make the dispute feel more urgent, personal, or adversarial than the underlying facts alone.
