Questions around cannabis and psychosis in anorexia are particularly important because patients may already be psychologically vulnerable. THC, the psychoactive compound in cannabis, has been linked to psychosis risk in some individuals, raising concerns about its safety in eating disorder care. 

For patients with anorexia, careful evaluation of mental health history is essential before cannabis is considered.

The Link Between Cannabis and Mental Health 

Cannabis interacts with brain pathways related to perception, mood, and thought processes, which may heighten certain risks. 

Mental Health Risk 

Patients with anorexia often face elevated mental health risks, including anxiety, depression, and obsessive thinking. Adding cannabis may amplify these vulnerabilities in some cases. 

THC Effects 

High levels of THC can increase paranoia, hallucinations, or disorganised thinking. These THC effects may contribute to psychotic episodes, especially in patients with pre-existing susceptibility. 

Vulnerable Patients 

Clinicians must be cautious with vulnerable patients, particularly those with a family or personal history of psychosis. Lower THC or CBD-dominant options may be safer alternatives. 

In summary, while cannabis and psychosis in anorexia are not universally linked, risks exist, particularly with high THC use. Close medical supervision and patient screening are crucial to ensure safety.
