CBD worsens cannabis effects in schizophrenia patients

A study found that CBD worsened memory and psychotic symptoms in schizophrenia patients using cannabis.

Why it matters

  • CBD, often thought to protect against THC's adverse effects, may not help schizophrenia patients.
  • This challenges previous beliefs about CBD's protective role.

By the numbers

  • Study involved a double-blind, randomized, placebo-controlled, crossover trial.
  • THC doses: 20 mg, 40 mg, 60 mg.
  • CBD dose: 1000 mg oral.

The big picture

  • Schizophrenia patients may face increased risks when using cannabis, especially with CBD.
  • Findings suggest CBD may not be universally protective against cannabis-induced symptoms.

What they're saying

  • Some commenters note that the study's scope is limited to schizophrenia patients and may not apply to others.
  • One commenter questioned the use of oral CBD instead of inhaled.

Caveats

  • The study was conducted in patients with comorbid CUD, so results may not apply to those without schizophrenia.
  • Findings may not generalize to non-schizophrenia populations.

What’s next

  • Further research is needed to understand CBD's effects in different populations and administration methods.
