New Yale study suggests key clinical, cognitive, and brain-based differences. Key points Modern high-potency cannabis may be changing the landscape of psychotic disorders. Cannabis psychosis may be more than a temporary drug-induced condition. Continued cannabis (THC) use may triple relapse risk despite taking antipsychotics.

But a quieter, equally deadly threat has taken root in the background, one that nobody can afford to ignore any longer. Drug impaired driving now claims hundreds of lives each year across the United States, and

Therapy, Not Tablets: The Real Picture of Cannabis Addiction Treatment The most comprehensive scientific review of its kind has found that no medication works for cannabis addiction treatment, while certain talking therapies offer more meaningful promise.
